THANK YOU FOR CHOOSING NAD.  
We encourage you to take a few minutes now to read right through this  
manual. Investing a little time here at the outset might save you a good  
deal of time later, and is by far the best way to ensure that you make the  
most of your investment in the NAD T 175, and get the most from this  
powerful and flexible home-theater component.  
The T 175 AV Tuner Preamplifier is a technologically advanced and highly  
capable product — yet we have invested great effort in making it simple  
and easy to use. The T 175 delivers a range of genuinely useful options  
for surround sound and stereo listening, using powerful digital signal  
processing and superbly accurate digital-audio circuitry. However, we have  
also been careful to ensure that the T 175 is as musically transparent and  
spatially accurate as possible, incorporating much of what we’ve learned  
from a quarter century’s experience designing audio and home-theater  
components. As with all our products, NAD’sMusic Firstdesign philosophy  
guided the T 175’s design, such that it can confidently promise you both  
state-of-the-art surround home-theater and audiophile-quality music  
listening for years to come.  
One more thing: We urge you to register your T 175 ownership on the NAD  
Worldwide Web site:

INTRODUCTION  
ABOUT THE T 175  
Though the T 175 is among the most technically sophisticated Tuner  
Preamplifier, we worked hard to make it one of the most musically  
transparent home-theater components available as well; this is what we  
mean by NAD’sMusic Firstdesign philosophy. Here are just few examples:  
ZONE  
The T 175 AV Tuner Preamplifier is equipped with three configurable Zones  
that make full use of video and pre-amp level audio outputs. The ZR 4  
remote control will allow you complete access to Zone 2 applications  
including access to volume On/Off and all sources inputs. Zone 3 and Zone  
4 could be configured and managed at the appropriate Zone OSD menu  
using the front panel navigations keys as well as the corresponding keys on  
the HTRC 1 remote control.  
High-performance components used throughout the Tuner  
Preamplifier’s analog audio circuits to maximize quality from all sources,  
including multi-channel analog sources such as DVD-Audio and SACD.  
Preamp output (all channels) and main-amp input jacks make potential  
expansion as flexible as possible.  
RS 232  
Zone pre-amp and video feed with assignable 12 V DC trigger control.  
An RS-232 port for advanced zone control and software update through  
a Windows® compatible PC.  
Flexible system configuration is possible with the RS-232 interface and  
NAD’s proprietary Windows® compatible software. We are also certified  
partners with AMX and Crestron and fully support these external devices.  
Gold-surfaced connectors are employed throughout to ensure  
maximum signal integrity.  
This interface allows complete remote control of the T 175 from any remote  
location via the PC. Complete remote control functionality is available to  
the user by interface software. See your NAD audio specialist for further  
information.  
E.A.R.S. AND DIGITAL SURROUND  
A key element of the T 175’s unique musical aptitude is NAD’s proprietary  
Enhanced Ambience Recovery System (EARS). In sharp contrast to many  
“ambience-synthesismusic-surround modes, EARS exploits the T 175’s  
substantial DSP power to route the ambient content that isencryptedin  
virtually all natural-acoustic recordings to the appropriate main, center and  
surround speakers, without resorting to artificially generated reflections  
or regeneration. EARSnatural ambience yields a subtle but exceptionally  
effective surround mode that naturally enhances the spatial presentation in  
a fashion suitable for serious music listening.  
UPGRADABILITY  
The T 175 AV Tuner Preamplifier permits flexible system growth via  
individually accessible pre-out and main-in jacks for all channels. We have  
made the more likely scenario of software upgrades easy to accomplish  
via the high speed RS-232 port on the rear panel of the T 175. Owners who  
will be advised of updates. Some of these may be free of charge, and some  
may require royalty payments depending on the type of upgrade. The  
advanced user will be able to perform these upgrades by downloading files  
from our web site, via e-mail and installing them by connecting the T 175 to  
a PC. Alternatively the dealer from whom you purchased your T 175 should  
be able to assist in performing these upgrades.  
Dolby Pro Logic IIx Music and DTS Neo:6 Music modes can also create  
enjoyable experience from 2-channel sources.  
On the digital side, the T 175 combines extraordinarily high-speed DSP  
processing employing one of the most advanced high-speed DSPengines”  
available, with fully 24-bit, 192 kHz-sampling-capable D/A converters for  
all channels. A single, high-precision master clock synchronizes all digital  
circuits to eliminate the timing errors (jitter) that otherwise compromise  
sonics. The result is legitimately state-of-the-art surround decoding from  
Dolby Digital and DTS sources, and 6.1/7.1-channel reproduction, with  
genuinely superior sound quality in all modes.  
ABOUT THE HTRC 1 SYSTEM REMOTE CONTROL  
Packed with your T 175 is the NAD HTRC 1 remote control, a full-system  
remote especially designed for easy use and understanding. Be sure to read  
the sectionUsing the HTRC 1 Remote Control, to familiarize yourself with  
the remote’s layout and operations before proceeding to setup your T 175.  
You may opt to use your HTRC 1 as your primary way to command your  
entire AV system. The HTRC 1 can be employed to operate additional NAD  
or other-brand components such as a DVD/CD player, television, satellite/  
HDTV tuner, VCR, or virtually anything else that operates via standard  
infrared remote.  
EASE OF USE  
Despite the effort NAD has invested in the T 175 AV Tuner Preamplifier’s  
sonic performance, we expended no less in making it powerfully easy to  
use. Its design is uniquely simple for so sophisticated a component, and  
the HTRC 1 universal remote control is equally understandable, as are the  
T 175’s own front-panel and on-screen displays. Its simple yet powerful  
system ofpresetspermits you to fine-tune your listening setup for different  
conditions, sources, or listeners, and to recall these multiple parameters  
with a single key press.  
INTEGRATION  
The T 175 AV Tuner Preamplifier offers extensive, flexible system-integration  
options through its configurable DC trigger outputs and input, and its  
standard-protocol IR communications links. The DC trigger outputs can be  
assigned to either Local and/or Zone locations.

This owner’s manual.  
SAVE THE PACKAGING  
Please save the box and all of the packaging in which your T 175 arrived. Should you move or  
otherwise need to transport your T 175, this is by far the safest container in which to do so. We’ve seen  
too many otherwise perfect components damaged in transit for lack of a proper shipping carton, so  
please: Save that box!  
CHOOSING A LOCATION  
Choose a location that is well ventilated (with at least several inches to both sides and behind), and  
that will provide a clear line of sight, within 23feet/7 meters, between the T 175’s front panel and your  
primary listening/viewing position—this will ensure reliable infrared remote control communications.  
The T 175 generates a modest amount of heat, but nothing that should trouble adjacent components.  
It is especially important that sufficient ventilation be provided. If you are contemplating on locating  
the T 175 within a cabinet or other furniture, consult your NAD audio/video specialist for advice on  
providing adequate airflow.  
QUICK START  
Packed with your T 175 is a Quick Start Guide that will guide you through typical setup configurations  
in combination with your ancillary devices. The Quick Start Guide also features the contents of your

ATTENTION!  
Please make sure that the T 175 is powered off or unplugged before making any connections. It is also advisable to power-down or unplug all associated  
components while making or breaking any signal or AC power connections.  
1
7.1 CH INPUT: Connect to the corresponding analog audio outputs  
of a multichannel source component such as a DVD-Audio or  
multichannel-SACD player or external multichannel decoder (disc copy  
protected formats only allow analog signal transfer). Typically, these  
sources will produce 5.1-channel output, in which case the Surround  
Back jacks are left unconnected. The signals present at these jacks may  
be heard by selecting Source 7 (7.1 Channel Input is defaulted to this  
Source).  
4
FM, AM ANTENNA INPUT: The supplied wiredipoleFM antenna will  
connect to the FM connector using the suppliedbalunadapter. It will  
usually work best when mounted on a vertical surface such as a wall,  
with arms fully outstretched forming a horizontal“T”perpendicular to  
the origin point of the signal.  
Connect the supplied AM loop antenna to these terminals. If an external  
AM antenna is used, make connections to the AM and GND terminals  
in accordance with the instructions supplied with the antenna. See also  
section aboutLISTENING TO RADIO.  
There is no bass-management or other processing (other than master-  
volume control) available to this 7.1 Channel Input. While the multi-  
channel audio outputs of a DVD-Video player can be connected to  
these jacks, using the T 175’s own Dolby Digital and DTS decoding and  
digital-analog converters via a digital connection will usually produce  
superior results.  
5
XM MODULE INPUT (North America version only): Connect XM  
radio cable to this socket. Follow the instructions that came with your  
XM radio. With XM radio, there are more than 100 channels of music,  
news, sports, comedy, talk and entertainment. You will find that the  
coverage is continent wide. The music quality is digital with many  
commercial-free music channels.  
2
AUDIO PRE-OUT: The Audio PRE- OUT makes it possible to use the  
T 175 as a pre-amplifier to external power amplifiers for some or all  
channels. Connect FRONT L, FRONT R, CENTER, SURR R, SURR L, SURR-  
BL, SURR-BR and CENTER to the respective channel input of a power  
amplifier or an amplifier driving the corresponding applicable speakers.  
NOTES  
or by calling (at the time of printing this manual) XM’s Listener Care at  
(800) 853 9696. Be ready with your Radio ID that can be found on the  
radio by selecting Channel 0.  
Unlike the full range channels, there is no power amplifier built-into the  
T 175 for a subwoofer. Connect the SUBW 1 or SUBW 2 output or both  
to powered (“active”) subwoofers or to power amplifier channels driving  
a passive system.  
DAB MODULE INPUT (Europe version only): Plug-in the other end  
of the Mini-Din connector from the NAD DAB Adaptor DB 1 module  
output port into this socket. The T 175 is compatible only with NAD

+12 V TRIGGER OUT: There are three configurable +12V TRIGGER  
OUTPUT. Use a 3.5mm mini-jack connector to pass +12 volts at a  
maximum current of 50 milliamps to auxiliary equipment such as a  
multichannel amplifier or subwoofer. The centre conductor (hot) of the  
3.5mm jack is the control signal. The outside conductor (shield) is the  
ground return-path.  
TRIGGER IN accepts 12V Trigger output of compatible components  
such as power controllers and home automation devices.  
TRIGGER OFF/AUTO : When at AUTO position, the T 175 selects the  
12V Trigger Input to turn ON (if so assigned at theTRIGGER SETUP”  
menu) and at the same time disables the HTRC 1 and front panel’s ON/  
OFF function. When set to [OFF] position, the trigger input is disabled.  
AUDIO 6 IN is advisable to connect to dedicated analog output from  
line-level audio sources like a CD player or Stereo tuner.  
10 MONITOR (S-VIDEO, VIDEO): Connect to video input of the monitor/  
television using quality dual-RCA and/or S-Video cables designed for  
video signals. In general, the S-Video connection is superior and should  
be used if your TV/monitor provides the corresponding input.

jacks to the analog audio/video input of a recording component  
such as a cassette deck, DVD recorder or to an outboard audio/video  
processor. Connect the T 175’s AUDIO 3 IN/VIDEO 3 IN or AUDIO 4  
IN/VIDEO 4 IN jacks to the component’s corresponding output.  
the TRIGGER switch is set to “AUTO” mode, the Power button in the front  
panel as well as the corresponding ON/OFF function keys in the HTRC 1  
remote control will be disabled effectively handing this function to an  
external controller. Switch TRIGGER to “OFF” to maintain normal power  
ON/OFF function procedures.  
The signal present at these T 175 AUDIO/VIDEO OUT jacks is determined  
by the source last selected via the front panel Source keys or the  
HTRC 1’s input select keys with the exception of Source 3 or Source  
4. There will be no output when Source 3 (Audio 3 IN/Video 3 IN)  
or Source 4 (Audio 4 IN/Video 4 in) is the selected source input.  
This prevents feedback through the recording component thereby  
preventing possible damage to your speakers.

USING THE T 175 – MAIN MENU  
PRO LOGIC  
Two-channel recordings, whether stereo or surround-encoded, are reproduced with Dolby Pro  
Logic surround processing, yielding output to front left/right, center and discrete left/right surround  
channels (assuming these are present in the currentSpeaker Configuration”). The surround channel is  
monophonic, but it is reproduced in both surround speakers.  
PRO LOGIC PLII  
Dolby Pro Logic II is a more recent evolution of the original Dolby Pro Logic surround processing that  
yields more stable imaging and full bandwidth sound to the rear channels in Movie mode, offering  
sound that is more similar to Dolby Digital decoding.  
PRO LOGIC IIx  
Dolby Pro Logic IIx processes both stereo and 5.1 signals into a 6.1 or 7.1 channel output. At Dolby  
Pro Logic IIx, you can choose PLIIx Movie or PLIIx Music modes to tailor your listening experience  
to the source material. Dolby Pro Logic IIx surround processing yields more stable imaging and  
full bandwidth sound to the rear channels in Movie mode offering sound that is more similar to  
Dolby Digital decoding. For two channel signals, Dolby Pro Logic IIx Music mode also features three  
additional user controls - Dimension, Center Width, and Panorama. See also section aboutADJUSTING

NEO:6  
Two-channel recordings, whether stereo or surround-encoded, are reproduced with Neo:6 surround  
with output to front left/right, center and discrete left/right surround channels plus subwoofer  
(assuming these are present in the currentSpeaker Configuration”). The T 175 provides two DTS Neo:6  
variations - CINEMA and MUSIC. See also section aboutADJUSTING LISTENING MODESbelow.  
EARS  
Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NAD  
surround processing with signals output to the front left/right, center and discrete left/right surround  
channels, plus subwoofer (assuming these are present in the currentSpeaker Configuration”). EARS  
does not employ the surround back speakers (if any).  
EARS extracts the natural ambience present in nearly all well-produced stereo recordings. It does not  
synthesize any ambience or other sonic elements and thus remains truer to the sound of the original  
musical performance than most other music-surround options.  
Select EARS for listening to stereo music recordings and broadcasts. EARS produces a subtle but highly  
natural and believable ambience from nearly allnatural-acousticstereo recordings. Typically, these  
include classical, jazz, and folk genres as well as numerous examples from others. Its virtues include  
realistic, stablefront-stagesonic imaging and spacious but unexaggerated ambientvirtual acoustics”  
that remain faithful to the original recording.  
ENHANCED STEREO  
All recordings reproduced in stereo via the maximum speaker complement configured in the current  
“Speaker Configuration. Enhanced stereo can be useful for maximum volume from all channels or for  
multi-speaker background music (cocktail party) listening. For this mode, Front, Center, Surround and  
Back speakers can be turned ON/OFF as desired.

ABOUT VIDEO FORMATS  
For many years, there was only one type of video format used. Composite video signals include the  
Luminance (black & White) and Chroma (color) signals combined on one wire. S-Video uses separate  
wires in a single cable for Luminance and Chroma signals. Component Video goes a step further  
with separate cables for Luminance and the two elements of Chroma. For NTSC (America, Japan)  
as well as PAL signals(Europe, Asia) these are labeled Y, Cr, Cb. Television studios use the Component  
Video format to keep these signals separate in order to maintain the best quality. As consumer video  
equipment has improved this higher quality format has been included.  
VIDEO FORMAT CONVERSION  
The T 175 is equipped with a Video Format Converter. This allows for a simplified video connection  
between the T 175 and your TV Monitor when using multiple video formats such as Composite (CVBS),  
S-Video, and Component (YUV). This format change is accomplished by encoding the analog video  
signal into a digital signal using a very high quality digital encoder to maintain the best possible  
picture quality. Once in a digital format, it can be decoded into any of the three standard analog video  
formats. These analog outputs are also up-converted to HDMI output. Video output availability will  
depend on the resolution capability of your TV/Monitor.  
It is suggested that you select the highest quality video format available on your TV Monitor and utilize this  
for your Monitor OUT connection from the T 175 to the TV Monitor. In most cases this will be Component  
Video or HDMI (where possible), but on some older TV’s S-Video may be the best quality connection.  
A/V PRESET  
A particular Source can be assigned a stored Preset. The parameters set up in the selected Preset  
number will be adopted into the particular Source it is assigned (Please refer to the separate section on  
“A/V PRESETSfor further understanding of Preset settings).

SPEAKER SETUP  
After connecting all ancillary sources and other combinations, the Speaker Setup menu will guide  
you on how to manage and setup your speakers in order to achieve optimum sound acoustics in your  
listening environment.  
The following are the Speaker Setup Menu sections.  
IMPORTANT NOTICE  
The T 175 is a Tuner Preamplifier only and therefore has no Speakers. The mention of “Speaker(s)” in  
this manual refers to your external amplifier’s speakers as interfaced with the T 175.  
AUDYSSEY AUTO CALIBRATION  
It has been shown that many, if not most, surround sound systems are not accurately setup and  
calibrated. To be done properly, calibration requires special knowledge and instrumentation that the  
average person probably doesn’t possess.  
The Audyssey Auto Calibration featured in T 175 uses a microphone, along with sophisticated digital  
electronics built into your T 175, to automatically setup and calibrate the T 175 to the exact speakers  
and speaker placement of your own unique Home Theatre.  
The following measurements are performed:  
Detection: Speaker configuration is detected including number of surround speakers and  
whether a subwoofer and center channel is connected.  
Size: T 175 crossover is set based on each channel’s signal handling capability and the subwoofer  
crossover is automatically set.  
Level: SPL of each speaker is matched within 1dB at the microphone position.  
Distance: is accurately set to within 1 foot (30 centimeters) of the microphone for each speaker  
position.  
Polarity: the setup program will detect and notify the user if any speakers are connected  
improperly. Incorrect polarity can ruin the illusion of realism offered by surround sound.  
This is a one-time set up, unless speakers are moved or changed, in which case the calibration should  
be performed again.  
AUDYSSEY MultEQ XT ROOM ACOUSTICS CORRECTION  
Sound reflecting from room boundaries can disturb the spatial illusion of surround sound, and can also  
distort the tonal balance of the system. Professional Acoustical Engineers often add wall treatments  
and even move walls and relocate speakers to improve system performance, but for the average Home  
Theatre, this is either too expensive or just not a practical solution.  
Audyssey MultEQ XT, using multiple measurements from the actual listening positions, and processing  
this information using very sophisticated digital signal processing, is able topreconditionthe signal to  
effectively make the walls disappear. This creates afamily sizesweet spot where the sound and spatial  
cues are very accurately reproduced.  
MultEQ XT is designed to tame room acoustics without changing the sonic character of your  
loudspeakers. While it will make the most of whatever loudspeakers you have, it will not make poor  
speakers sound like good ones!  
Connect the Audyssey microphone jack into the front panel’s MP/MIC input and the Audyssey Auto  
Calibration wizard will guide you through a simple step-by-step configuration. Once setup and  
calibrated, the next greatest improvement in performance is obtained by eliminating the acoustic  
interference caused by room boundaries interacting with your speakers.

OPERATION  
USING THE T 175 –SETUP MENU  
MEASUREMENT IS THE FIRST STEP.  
The sound at each listening position (up to 8 positions) is calibrated using the same microphone used  
during the setup phase.  
A special test tone is sent to each speaker and the data is memorized by the T 175. The duration of  
calibration may take some time depending on the number of speakers as well as the number of  
measuring points. After all positions are measured, the DSP calculates the ideal system response for  
your particular room and speaker setup.  
If some inconsistencies or discrepancies are detected during the Audyssey calibration, the process  
maybe interrupted or the problem is shown in the particular setup window. A notice screen is  
correspondingly displayed. After following and undertaking the displayed instructions, re-start the  
Audyssey calibration again. When the measurements are finalized, Audyssey calculates the ideal  
system response for your particular room and speaker setup.  
NOTE  
The test tone emitted during measurement is loud. This maybe bothersome for you and may affect  
as well your other household members and even your neighbor.  
NEXT A TARGET CURVE MUST BE CHOSEN.  
Because loudspeaker designers assume that their products will be used in typical domestic rooms,  
they arevoicedto work in this environment. It is assumed that the room will add some bass  
reinforcement and will absorb some treble energy. Thus if we effectivelyremovethe walls with room  
correction, and set the speakers for flat response, you may find this sounds too bright in the treble and  
too weak in the bass region.  
NAD engineers have done extensive research in this area of room acoustics, and along with Audyssey  
engineers developed what we believe is the idealin roomresponse curve. We include this NAD EQ,  
along with an Audyssey developed EQ as the two best choices. The response curves shown below  
typify NAD EQ room correction process.  
Room Response measured by Audyssey microphone  
Inverse Correction Filter calculated by NAD T 175  
Corrected Room Response  
Flat EQ is a third option, but not one that we recommend for listening (it is useful for verifying system  
performance when using external instrumentation).  
Select the Target Curve you find to be most satisfactory by pressing the Audyssey key of the remote.  
The MultEQ XT corrected response can also be bypassed if you wish.  
It is recommended that you take full advantage of the T 175’s Audyssey Auto Calibration feature for  
your speaker setup. However, if you desire to setup your speakers manually or if you already had run  
Audyssey Auto Calibration but would like to make adjustments, the following sections on Speaker  
Configuration, Speaker Levels and Speaker Distance can also be followed and implemented.  
NOTE  
During manual setting of your speakers, previously calibrated Audyssey settings could be retrieved  
by re-adjusting back the altered configurations as highlighted by an asterisk.

due to acoustic cancellation effects, the bass response may be uneven when using this setting.  
You can set Subwoofer toOneven withLargefront speakers, in which case bass content from any

signal will pass only to the sub. In most subwoofer-equipped systems, setting front speakers toSmall”  
is usually the better option.  
All the speakerslow frequency content can be directly adjusted within the range 40Hz to 200Hz.  
NOTE  
The configurations set forth at “Speaker Setup” are carried over whenever it is enabled during A/V  
Preset setting. Please see also the section “A/V PRESETS” for reference.  
SPEAKER LEVELS  
Adjusting the relative balance of your system’s loudspeakers ensures that surround-sound recordings,  
whether music or film, will present the balance of effects, music, and dialog that the artists intended.  
Additionally, if your system incorporates a subwoofer it establishes a correct relationship between the  
volume of the subwoofer and the other speakers, and thus of low-frequencies (bass) to other sonic  
elements.  
USING AN SPL METER  
It is quite practical to perform the T 175 level setup routinesby ear,and careful work will produce  
acceptably accurate results. However, the use of an inexpensive sound-pressure level (SPL) meter,  
such as Radio Shack part number 33-2050, makes this task easier, more accurate and more repeatable.  
Ownership of such a meter could prove a valuable audio tool. Your NAD audio specialist may be able  
to help you with temporary use of a meter.  
The SPL meter should be placed at the primary listening position, at approximately the height of  
the seated listener’s head. A tripod is helpful but with a little duct tape almost anything — a pole  
lamp, music-stand, or ladder-backed chair, for example — can do as well. Just be sure that no large  
acoustically reflective surfaces obstruct or are near the microphone element.  
Orient the meter with its microphone (usually at one end) pointing straight up toward the ceiling (not  
toward the speakers) and ensure thatCweighting scale is selected. Set the meter to display 75 dB  
SPL. On Radio Shack meters, this necessitates either setting the meter to its 80 dB range and taking  
your readings at the -5 point or selecting the 70 dB range and reading at the +5 point.  
SETTING SPEAKER LEVELS AT TEST MODE  
While atSpeaker Levelsmenu, press the HTRC 1 remote’sTestkey activating the T 175’s Speaker  
Levels balancing test signal . You will hear asurfsound as you step through your speakers (“test”  
appears to the right side of the current speaker), beginning with the Front Left. If you do not hear the  
test signal, check your speaker connections or yourSpeaker Setupmenu settings.  
Use the remote’s [  
] keys to adjust the loudness of the noise output from the currently playing  
channel to the required level (it’s usually simplest to begin with the Front Left). As you cycle the test  
signal around the speakers, the OSD will highlight the currently playing channel. Thelevel offset”  
reading on the right will change by 1 dB increments; 12 dB adjustment is available. PressENTERto  
adjust the next speaker.  
NOTE  
If you are balancing levels “by ear, choose one speaker—usually the center— as a reference and  
adjust each of the others in turn to “sound as loud” as the reference. Be sure that you remain in the  
primary listening position while balancing all channels.

SPEAKER DISTANCE  
Your system’s speaker distance settings are a subtle but important refinement of your setup. Informing  
the T 175 of the loudspeaker-to-listener dimensions of each speaker automatically imposes the correct  
delays, optimizing imaging, intelligibility and surround-sound ambience. Enter your dimensions with  
precision within about 1 foot (30 cm).

Since recordings vary considerably in overall average level, there is no imperative to listen at any  
particular master-volume setting. A setting of -20 may soundas loudfrom one CD or DVD as -10 does  
from another.  
The T 175 will power-up from Standby mode at whatever master volume setting was last used;  
however, if the prior setting was greater than –20 dB, the T 175 will power up at –20 dB. This prevents  
inadvertently beginning a session at excessive volume.  
MUTING THE SOUND  
Use the HTRC 1’sMutekey to silence all channels completely. Muting is always available regardless of  
the source or listening mode selections.

ADJUSTING CHANNEL LEVELS “ON THE FLY”  
You can make changes to the relative levels of center, surround and subwoofer outputs without  
having to go into theSpeaker Levelsmenu. This is very convenient in circumstances like increasing  
(or tone down) a film’s dialog level by rising (lowering) the center channel or reducing excessive deep  
bass (or enhance deep bass) by lowering (rising) the subwoofer level.  
Use the HTRC 1’s [SURR], [CENT] and [SUB] keys for direct-access level adjustment of these channels  
over a range of 6 dB.  
The surround back channels (if any) adjust in lockstep with the surround channels.  
NOTE  
Level settings adjusted “on the fly” are added or subtracted to the setup levels established at the  
T 175 level-calibration routine as invoked by the HTRC 1 “Test” key. However, selecting any Preset  
will revert the channel levels to those stored in the preset. It will also take T 175 off the levels set via  
Audyssey Auto Calibration.  
ZONE SETUP  
The Zone feature allows one to simultaneously experience in different zones of the house multiple  
sound and applicable video sources from all enabled Sources as well as from Front Input, Media Player  
and Tuner.  
The T 175 has three configurable Zones – Zone 2, Zone 3 and Zone 4. Use a combination of [ ] or  
[ENTER] and [  
] keys to navigate through the Zone Setup menu parameters.  
VOLUME  
Zone 2 have Fixed and Variable volume control. When set toVariable, the Zone 2 Volume is directly  
adjustable using [ ] cursor keys of the HTRC 1 or [Volume ] keys of ZR 4.  
On the other hand, if Volume is set toFixed, the Zone 2 Volume is set to a preset dB level and thereafter  
the zone’s volume can be varied via the volume control of the separate amplifier it is fed into.  
MODE  
Zone 3 and Zone 4 can be configured into two modes – Record Out and Zone (Audio Only). If the  
selected mode is Record Out, the audio and applicable video signal of the assigned Source are directly  
sent out to the applicable Audio/Video Output (See Item 11. AUDIO 3 OUT/VIDEO 3 OUT, AUDIO 4  
OUT/VIDEO 4 OUT of REAR PANEL discussion.) When Zone 3 or Zone 4 is set toRecord Outmode,  
they will not be available at theZone Controlssection of the Setup Menu window.  
“Record Outsetting is ideal for making recordings with a VCR or other similar devices. This setting is also

TRIGGER OUT  
Triggers are low voltage signals used to turn on/off other compliant devices. The T 175’s three +12V DC  
Trigger Outputs (Trigger 1 Out, Trigger 2 Out and Trigger 3 Out) are dependent on which mode they  
are associated with. There are six choices where +12V DC output can be assigned and these are – Main,  
Zone 2, Zone 3, Zone 4, Zone 2+3+4 and Source Setup.  
Main: +12V DC is available at the assigned Trigger Out when the T 175 is at powered state.  
Zone 2, Zone 3, Zone 4, Zone 2+3+4: When the applicable Zone is at powered state, +1 2V DC  
is available at the assigned Trigger Out.  
Source Setup: If Trigger Output is linked toSource Setup, +12V DC is available at Trigger Out  
whenever the particularly assigned Source is selected. Please see also separate discussion about  
“TRIGGER OUTunder theSource Setup (Normal View)section.  
DELAY  
The availability of +12V DC at Trigger OUT can be regulated. If it is desired that +12V DC is available  
without delay the moment Trigger OUT is linked to its assigned setting, set Delay to 0s. Otherwise, one  
can select through a delay time of 1s to 15s.  
AUTO TRIGGER IN  
Auto Trigger IN allows external system controllers to toggle the associated section of the T 175 from  
“StandbytoOnand vice versa. When the TRIGGER switch at the rear panel is set to ON, a +12V DC  
input at Trigger IN will power ON the section where Trigger IN is assigned,  
Main: From standby mode, the T 175 is powered ON when +12V DC is applied at Trigger IN.  
Zone 2, Zone 3, Zone 4: Applicable Zone is turned ON whenever +1 2V DC is present at Trigger IN.  
All: Main, Zone 2, Zone 3 and Zone 4 as described above will all be activated given a +12V DC input at  
Trigger IN.  
WARNING  
If Auto Trigger IN at Trigger Setup menu is assigned to “Main” or “All” and the TRIGGER switch is set  
to “AUTO” mode, the Power button in the front panel as well as the corresponding ON/OFF function  
keys in the HTRC 1 remote control will be disabled effectively handing this function to an external

LISTENING MODE SETUP  
The T 175 has various listening mode options and is mostly configurable. These are provided to  
reproduce a variety of sound effects depending upon the content of the source to be played. Use a  
combination of [ ] or [ENTER] and [  
] keys to configure the following settings.  
LISTENING MODES  
The audio format as detected by the selected Source can be automatically configured and processed  
through the following options:  
DOLBY DIGITAL  
Dolby Digital is the multi-channel digital signal format developed in the Dolby laboratories. Discs  
bearing the double-D symbol were recorded with up to 5.1 channels of digital signals, reproducing a  
much better sound quality, with dynamic and spatial sound sensations that are much better than in  
the previous Dolby Surround.  
A Dolby Digital audio input can be configured relative to its format.  
2 Channel: If the detected audio is a 2 Channel Dolby Digital signal, you can default it to one of  
the following settings – Pro Logic, PLIIx Movie, PLIIx Music or None.  
Surround: If the detected audio is a Surround Dolby Digital signal, you can default it to one of the  
following settings –Surround EX, PLIIx Movie, and PLIIx Music, Stereo Downmix or None.  
None: IfNoneis selected, the Dolby Digital format will follow theDigitalsetting set forth at

OPERATION  
USING THE T 175 –SETUP MENU  
DOLBY DIGITAL EX  
Using a Matrix decoder, this method creates the back channel (sometimes also called thesurround  
center”) by means of signals on the left and right surround channels recorded in Dolby Digital 5.1,  
reproduction being provided in Surround 6.1. This method should be selected with sources bearing  
the (double-D symbol)-EX, recorded in Dolby Digital Surround EX.  
With this additional channel you will experience improved dynamics and a better sensation of  
movement within the sound field. If media sources recorded in Dolby Digital EX are decoded with a  
Digital EX decoder, the format is detected automatically, and the Dolby Digital EX mode is selected.  
However, some media sources recorded in Dolby Digital EX can be detected as simple Dolby Digital  
media sources. In this case Dolby Digital EX should be selected manually.  
NOTE  
Please refer to the section “LISTENING MODE” at the Main Menu discussions for a description of Pro  
Logic, PLIIx Movie, PLIIx Music and Stereo Downmix modes.  
DTS  
The Digital Theater System Digital Surround (simply called DTS) is a multi-channel digital signal format  
that can process higher data rates than with Dolby Digital. Although both Dolby Digital and DTS are  
5.1 channel media formats, discs bearing theDTSsymbol are thought to provide better sound quality  
due to the lower audio compression required. It also offers a broader dynamic, producing magnificent  
sound quality.  
A DTS input can be defaulted to one of the following options: - Neo:6 Music, Stereo Downmix or None.  
IfNoneis selected, the DTS signal will follow theDigitalsetting set forth atOtheroption under this  
menu section. See discussion below aboutOther.  
NOTE  
Please refer to the section “LISTENING MODE” at the Main Menu discussions for a description of  
Stereo Downmix and DTS Neo:6 surround modes.  
OTHER  
IfNoneis selected above for any of the Dolby Digital 2 Channel, Dolby Digital Surround and DTS  
options or if the audio input is an analog signal, thisOthersection will manage the default audio  
format as per theDigitalorAnalogsettings.  
Digital: The detected digital input can be configured by way of one of the following options  
- Pro Logic, PLIIx Movie, PLIIx Music, Neo:6 Cinema, Neo:6 Music, EARS, Enhanced Stereo, Stereo  
Downmix and None.  
Analog: If the audio input is an analog signal, the following are the surround modes the input  
can be defaulted - Pro Logic, PLIIx Movie, PLIIx Music, Neo:6 Cinema, Neo:6 Music, EARS, Enhanced  
Stereo, Analog Bypass and None.  
NOTE  
All these Listening Modes for “Dolby Digital, DTS” and “Other” can be directly changed by pressing  
the “LISTENING MODE” button on the front panel or through the “Listening Mode” option at the  
Main Menu window. The chosen audio format will be reflected back to the appropriate setting at  
the “Listening Mode Setup.  
DOLBY SETUP  
Under this menu, the Dolby Digital’s Dynamic Range Control can be adjusted as well as the settings for  
Dolby Digital Pro Logic IIx Music.  
Dynamic Range Control: You can select the effective dynamic range (subjective range from soft  
to loud) for playback of Dolby Digital soundtracks. For fully cinematic effect, always select 100%,  
the default. Settings of 75%, 50%, and 25% progressively reduce dynamic range, making soft  
sounds comparatively louder while limiting the peak loudness of loud ones.  
The 25% setting will yield the least dynamic range and is best for late-night sessions or other times  
when you wish to retain maximum dialog intelligibility while minimizing overall volume levels.

under theLISTENING MODEof the Main Menu discussions.  
DTS SURROUND MODES  
The following are further descriptions about the DTS surround modes.  
DTS - ES EXPANDED SURROUND ™ (DTS ES)  
This is a new multi-channel digital format which greatly improves the 360° spatial sensation of the  
Surround impression thanks to the greater space expansion of the surround signals, providing high  
compatibility with the conventional DTS format.  
In addition to the 5.1 channels, the expanded DTS-ES Surround also offers the back surround (also  
sometimes called thesurround centre”) in reproduction, providing a total of 6.1 channels. The  
expanded DTS-ES Surround includes two formats, with two different methods of surround signal  
recording, as follows:  
DTS-ES™ DISCRETE 6.1  
Since the signals of the 6.1 Surround channels (including the back channel) are completely  
independent, it is possible to achieve the sensation that the acoustic image is moving about freely  
among the background sounds, 360 degrees surrounding the listener.  
Although maximum quality is achieved with sound tracks recorded using this system and reproduced  
using the DTS-ES decoder, when played with a conventional DTS decoder, the back surround channel  
is automatically downmixed in the surround right and surround left channels of the surround system,  
in such a way that none of the signal components are lost.  
DTS - ES™ MATRIX 6.1  
In this format, the additional signals of the back channel receive a matrix encoding and are inputted  
into the right and left surround channels. During reproduction they are decoded to the right, left and  
back surround channels.  
Since this bit-stream format is 100% compatible with conventional DTS signals, the DTS-ES Matrix 6.1  
format effect can also be achieved from sources with DTS-ES 5.1 signals.  
Naturally, it is also possible to reproduce from a DTS 5.1 channel decoder, signals recorded in  
DTS–ES 6.1.  
When a DTS-ES decoder processes a discrete DTS-ES 6.1 or in Matrix 6.1, these formats are  
automatically detected and the Optimum Surround mode is selected. However, some DTS-ES Matrix  
6.1 sources may be detected as DTS. In this case the DTS-ES Matrix mode should be selected manually  
in order to reproduce them.  
DTS NEO:6™ SURROUND  
This mode applies the conventional 2-channel signals such as digital PCM or analog stereo signals to  
the high precision digital matrix decoder used for DTS-ES Matrix 6.1 to achieve 6.1-channel surround  
playback. DTS Neo:6 surround includes two modes for selecting the optimum decoding of the signal  
sources:  
DTS NEO:6 CINEMA : This method is ideal for the reproduction of movies. The decoding takes  
place by emphasizing the separation in order to achieve the same atmosphere with 2-channel, as  
with 6.1-channel sources.  
DTS NEO:6 MUSIC : Mainly recommended for music reproduction. The right and left front  
channels do not pass through the decoder and are reproduced directly so there is no loss in sound  
quality, and the effects of the right surround, left surround, central and back surround channels add  
a natural sensation of expansion of the sound field.

USING THE T 175 – AM/FM/DB/iPod  
LISTENING TO RADIO  
The T 175’s internal AM/FM tuner offers very high quality sound from radio broadcasts. The reception  
and sound quality will always be dependent to a degree however on the type of antenna(s) used as  
well as proximity to the broadcast origin, geography and weather conditions.  
ABOUT ANTENNAS  
The supplied ribbon-wire FM antenna can be connected to the rear-panel FM-antenna input using the  
includedbalunadapter and should be fully extended to form a“T. This folded-dipole antenna will usually  
work best when oriented vertically, with the arms of its“T”fully outstretched and arranged perpendicular  
to the origin of the desired broadcast. There are no rules however, and experimenting freely with antenna  
placement and orientation may yield the clearest sound and lowest background noise.  
In areas of poor FM reception, an exterior FM antenna can improve performance dramatically. If  
radio listening is important to you, consider consulting an antenna installation professional to  
optimize your system.  
The supplied AMloopantenna will usually provide adequate reception. However, an exterior AM  
antenna can be used to improve reception. Consult an antenna professional for more information.

ABOUT DAB RADIO  
The bars show the progress of the sequence. When scanning is  
completed, the last number shown on the right side of the VFD  
corresponds to the total number of DAB broadcast stations found. Then,  
the first station is tuned in (SeeALPHANUMERICsection below to  
understand the order or arrangement of stations).  
Until now, analogue radio signals such as FM or AM have been subject to  
numerous kinds of interference on their way from the transmitter to your  
radio. These problems were caused by mountains, high-rise buildings  
and weather conditions. With Digital Audio Broadcast (DAB), you can now  
receive CD-like quality radio programs without any annoying interference  
and signal distortion. DAB broadcasts use digital signals rather than  
traditional analogue transmissions, thus providing clear high quality  
reception. You get far more robust reception and virtually hiss or crackle  
free sound with DAB as long as you are within a good coverage area.  
4
The strength of the incoming signal can be shown on the VFD by  
pressing the [ENTER] button. The more segments visible in the lower  
display line, the stronger the signal. By changing the position of the  
antenna, you can increase the signal strength. You can also opt for an  
external antenna. Consult an antenna professional for more information.  
With DAB, the listener can scroll through a list of available stations - then  
instantly tune to the station of his choice. There is no need either to  
remember channel frequencies. All broadcasts are selected by simply  
selecting the service name.  
The T 175 makes it possible for you to enjoy listening to DAB broadcasts.  
The T 175 has a Digital Audio Broadcast (DAB) module socket on the rear  
panel for adding a separately sold and NAD-specified outboard DAB  
module – the NAD DAB Adaptor DB 1. All the control software for this  
format is included; just plug-in the module and start enjoying the CD-like  
quality sound and expansive content selection available with DAB.  
NOTES  
“No Service List” will also be shown in the VFD when no stations are

OPERATION  
USING THE HTRC 1 REMOTE CONTROL  
IDENTIFICATION OF CONTROLS  
Top section features ON/OFF buttons and back-light LCD display.  
Upper section has eight DEVICE SELECTOR keys including one programmable CUSTOM DEVICE  
SELECTOR key and an additional MACRO button function key.  
The upper middle section with channel, volume, MUTE, and surround mode buttons.  
Middle section has DVD, CD, TUNER and OSD navigation buttons.  
Lower middle section has number buttons 0 to 9, A/V PSET, SPEAKER and CD functions, DVD

Bottom section with CHANNEL VOLUME trimming buttons.  
INTRODUCTION  
The HTRC 1 is like having eight virtual remote controls in one. The eight DEVICE SELECTOR keys can be  
used to switch between the different virtual remote controls or devices.  
When the HTRC 1 is idle, the name of the currently selected device will be shown on the first line  
of the LCD display. Whenever a function key is pressed, the name of that function will be shown on  
the second line of the LCD display. The second line will be cleared again shortly after releasing the  
function key.  
HIGHLIGHTS  
Controls up to 8 Devices.  
2-line LCD display indicates selected Device (DVD) and sent Command (PLAY) (for example).  
Preprogrammed with all NAD remote commands including Zone 2.  
Learning function - learns up to 360 commands from other remotes.  
Macro operations - program up to 52 Macros with as many as 64 commands each to automate  
commonly used command sequences.  
Punch Though Operations permit easy access to commonly used functions without reselecting a  
device.  
Full illumination with light sensor and adjustable time out for easy operation in low light  
conditions.  
Can generate IR signals with a carrier frequency up to 500 kHz (B&O® compatible).  
Mini USB PC Interface allows programming from a Personal Computer.  
The HTRC 1 is already preprogrammed with a full complement of NAD commands on its AMP DEVICE  
SELECTOR page, and with library commands to operate most NAD DVD, CD and TUNER components  
on the corresponding DEVICE SELECTOR keys. These default commands are permanent: Even if you  
teach the HTRC 1 new commands to take their place, the underlying library commands remain in  
place and can easily be recalled should you add an NAD component to your system later.  
GETTING FAMILIAR WITH THE HTRC 1  
The HTRC 1 is divided into three main sections. The LCD display section at the top of the handset, the  
DEVICE SELECTOR, and the remaining 44 Control keys.  
Eight DEVICE SELECTOR keys at the top; AMP, TV, CUSTOM, CD, DVD, VCR, TUNER, and CABLE/SAT  
determine which component the remaining 44 control keys will operate. A DEVICE SELECTOR key  
determines what component the HTRC 1 will command; with factory defaults, it does not perform any  
function on the T 175. The DEVICE SELECTOR keys are organized into three vertical rows of 3 buttons  
each; the row on the left are all Audio devices, the row in the center are all Video devices.  
Both the DEVICE SELECTOR and function keys canlearncontrol codes from virtually any infrared  
remote controller, allowing you to teach the codes of your equipment, regardless of brand, to the  
HTRC 1. All of the function keys on the AMP DEVICE SELECTOR are preprogrammed to control NAD  
amplifiers, preamplifiers, and receivers. (The HTRC 1 can also command many other NAD components,  
from its DVD, CD, TUNER and TV pages.)  
Since HTRC 1 Control keys can perform different functions, depending on the selected DEVICE  
SELECTOR key, the HTRC 1 uses color coding to indicate the function of the function keys when  
different device keys are chosen. Thus, the colour of the DEVICE SELECTOR key-labeling corresponds to  
the labeling of the function keys (similar to a calculator).

OPERATION  
USING THE HTRC 1 REMOTE CONTROL  
For example, the grey AMP DEVICE SELECTOR key label corresponds to the  
grey input-select labeling adjacent to the numeric keys: When the HTRC  
1’s AMP DEVICE SELECTOR page is active, these keys select the amplifier  
or receiver inputs. Similarly, the red DVD DEVICE SELECTOR key label  
corresponds to several red labels, the green TV DEVICE SELECTOR key to  
green labels, and so on.

NAVIGATION OF THE HTRC 1 CONTROLS  
DEVICE SELECTOR KEYS  
Simply pressing a DEVICE SELECTOR key will change the active device on  
the HTRC 1. At this time, no IR commands will be transmitted. The name of  
the selected device will be shown on the first line of the LCD display.  
For options which can be changed, the Right and Left keys are used to  
cycle through the available options. Left and Right arrows will be shown  
on the display to indicate when an option can be changed.  
Press ENTER to select a menu option or confirm a value.  
While a setup menu page is being executed, the corresponding first  
letter of the selected setup feature (i.e. “LwhenLibraryis the selected  
SETUP) is shown in the upper right corner of the display.  
NOTE  
Any IR command can be associated with a DEVICE SELECTOR key during  
“Copy” and “Learn” modes. Once the associated function is assigned to  
the DEVICE SELECTOR key, pressing and holding the DEVICE SELECTOR  
key for more than two seconds will send the associated command in  
addition to the HTRC 1 switching its active device.  
The following are the SETUP menu parameters.  
BATTERY  
Instead of waiting until theLow Battwarning is displayed, you can check  
the current battery level using this option. This option will show a bar graph  
representing the current battery level. When the batteries are new, the bar  
graph will show 8 bars. Once the bar graph reaches close to zero, theLow  
Battwarning will start to show.  
MACRO KEYS  
A macro can be associated with every key on the HTRC 1 except for the  
MACRO button itself. A total of 52 macros can be stored. To execute a macro:  
Press the MACRO key. The first line of the LCD display will showMACRO.”  
Within five seconds, press the key the macro is associated with.  
While the macro is executing a small "M" will be shown in the top right  
of the LCD display.  
Refer also to theMACROitem below of theHTRC 1 SETUP MENUsection  
for information on how to setup macros.  
LOW BATTERY WARNING  
If the HTRC 1 senses the batteries are low, it will showLow Batton the  
second line of the LCD display whenever the remote is idle. When this  
occurs the batteries should be replaced with new ones immediately.  
FUNCTION KEYS  
There are 44 dedicated function keys on the HTRC 1. When you press a  
function key, the name of the function will be shown on the second line of  
the LCD display while the command is being transmitted.  
BACK LIGHT SENSITIVITY (B LIGHT)  
The HTRC 1 is equipped with a backlight to increase visibility of the HTRC 1  
in low light conditions. The HTRC 1 also includes a light sensor. By default, if  
you press any key on the remote and it senses a low light condition, the back  
light will turn on. It will then turn off again five seconds after no key has been  
pressed. The behavior and timeout for the backlight can be adjusted.  
A/V PSET KEY  
In the default configuration of the HTRC 1, the A/V PSET key acts as a shift  
function when the AMP device is selected. Pressing the A/V PSET key  
once will causePresetto be displayed on the first line of the LCD display.  
If within five seconds you then press a digit (0 – 9), the function for the  
corresponding A/V Preset will be transmitted.  
NOTE  
The HTRC 1 is a universal-type remote control; some NAD receivers may  
not have more than 5 AV presets.  
TIMEOUT: The backlight timeout can be set from 0 - 20 seconds. This is the  
length of time the backlight stays ON after releasing the last key.  
SOFTWARE VERSION NUMBER

MACRO  
Amacrocommand is a series of two or more remote codes issued  
automatically from a single keypress. You might use a macro to automate  
a simple command sequence, such as, “Turn on the DVD player and then  
pressplay.Or you might compose an elaborate macro to power up  
an entire system, select a source, choose a Listening Mode, and begin  
playback—again, all from a single keypress. The HTRC 1 can store one  
macro to all its function keys except MACRO.  
Press [SURR MODE] button.  
Macros will be executed with the same timing as they were recorded. The  
length of time each command is sent will also correspond to the same  
length of time the key will be held down while recording.  
Use [  
] to select betweenNo(desired function key will not be  
deleted) andYes(desired function key is deleted and process is  
completed).  
Example: Record a Macro to the [0] key to turn ON the NAD T 175, Select  
[Input 1], turn ON the NAD T515 DVD Player, and commence disc playback  
of the connected Input 1 device (as in the NAD T515 DVD player):

OPERATION  
USING THE HTRC 1 REMOTE CONTROL  
BATTERY INSTALLATION  
SLEEP MODE  
The Sleep Mode timer will switch the T 175 to Standby mode automatically  
after a preset number of minutes. Pressing the HTRC 1’s SLEEP button once  
will display the setting of the sleep time increment. Pressing the HTRC 1’s  
SLEEP button a second time within a 3-second period will change the  
sleep time increment in 15-minute intervals, after which time the T 175 will  
automatically switch into Standby mode.  
To adjust the sleep delay, press the HTRC 1’s SLEEP button twice; first  
to display the sleep time increment, and a second time to change the  
sleep time increment. The sleep time increment and aSLEEPicon will  
continuously display on the T 175’s front panel Vacuum Fluorescent Display  
(VFD). Each consecutive press increases the sleep time in 15-minute  
increments from 15 to 90 minutes. To cancel the sleep mode, continue  
pressing the HTRC 1’s SLEEP button untilSLEEP OFFdisplays on the VFD.  
Switching the T 175 to standby from either the HTRC 1’s OFF or the T 175’s  
POWER button will also cancel the sleep mode

USING THE ZR 4 REMOTE CONTROL  
The ZR 4 remote control is a discrete compact remote for controlling the  
T 175 from various rooms other than the main room. The ZR 4 remote  
allows full separate control of the source selection irrespective to the main  
room. This means the zone input may be completely different, audio and  
video, from the main input and thus corresponding volume levels as well.  
If one wishes to enjoy the same source, as the main room the ZR 4 remote  
has a [LOCAL] button to allow simultaneous listening, but with full separate  
volume levels.  
Place batteries into opening. Ensure the correct polarity is observed  
To mute the Zone Volume level, press [MUTE] on the ZR 4. If theZone  
ControlsOSD menu is ON, the ZoneVolumelevel section will displayMute.  
The T 175’s front florescent display will show activity of the zone control  
so that main room occupants are aware of the zone remote activity.  
Furthermore if there is no main room activity, only the zone indicator will  
be active in the T 175’s fluorescent display.  
NOTE  
The ZR 4 remote control will only control Zone 2 applications. Zone 3  
and Zone 4 could be configured and managed at the appropriate  
Zone OSD menu using the front panel navigations keys as well as  
the corresponding keys on the HTRC 1 remote control. The HTRC 1’s  
“CUSTOM” device is also defaulted to Zone 2 remote control codes.
