Introduction  
Functional Description  
Thank you for selecting ATI’s ATP 8500 Digital Preamplifier-Processor for your audio and video home theater.  
The ATP 8500 is the center of a high-end cinema and audio system. The ATP 8500 decodes Dolby Digital, DTS and  
Dolby Pro Logic. Naturally, the ATP 8500 can also function as a High-End stereo preamplifier, and the digital signal  
processing and conversion can be bypassed. The 7.1 channel input is provided with comprehensive volume control  
facilities. This ensures that ATP 8500 will remain compatible with new multi-channel formats to appear in the future.  
For audio, the ATP 8500 accepts up to six digital input sources, ten line level input sources, a tape loop and two  
additional record outputs. For video, it has six S-Video and composite inputs, S-Video and composite monitor outputs,  
S-Video and composite video record outputs and an S-Video monitor output without OSD (On Screen Display).  
For Component Video, the ATP 8500 offers 3 sets of inputs and one set of outputs. If you are using all three types of  
video (composite, S-VHS, and component), you need to connect each output from the ATP 8500 to the appropriate  
connectors on the rear of your TV or monitor. You then switch between video formats with your TV’s remote (or a  
“smart system” remote control).  
The ATP 8500 has two main modes of function: In the normal function mode, the ATP 8500 automatically senses the  
type of the incoming signal and selects the mode that gives optimal reproduction quality. The user can switch off the  
automatic selection and select different post-processing modes for the incoming signals. These modes are stereo, Dolby  
Pro-Logic, mono down-mixing and four Music Modes: Natural, Concert, Club and Party. If desired, the user can bypass  
the digital section of ATP 8500 and connect, for example, a stereo source to the Left and Right channels of the balanced  
XLR inputs.  
System integration options are provided by the three 12VDC trigger outputs and one trigger input to control external  
equipment and by communication with a PC or home automation system via the RS 232 serial interface (DB-9 connector).  
Software Version  
In order to verify which version software you have installed in the ATP 8500, push and hold the front panel power  
button for a few seconds and the software version number will appear under the “ATI” name on the LCD.  
Unpacking  
The ATP 8500 has been carefully inspected, tested and packed before leaving the factory. Immediately upon receiving  
your preamplifier-processor, inspect the carton for evidence of mishandling during shipment. Then, carefully unpack  
the preamplifier-processor and inspect it for damage. Please save the shipping carton and all inner packing materials  
in the event that the preamplifier-processor needs to be shipped for service or moved to a new location. Should you  
discover that the preamplifier-processor has been damaged during shipping, please contact your dealer or ATI  
immediately and request the name of the carrier so a written claim can be made.  
THE RIGHT TO A CLAIM AGAINST A PUBLIC CARRIER CAN BE FORFEITED IF THE CARRIER IS NOT NOTIFIED  
PROMPTLY IN WRITING AND IF THE SHIPPING CARTON AND PACKING MATERIALS ARE NOT AVAILABLE  
FOR INSPECTION BY THE CARRIER. SAVE ALL PACKING MATERIALS UNTIL THE CLAIM HAS BEEN SETTLED.

Safety Instructions  
NOTE FOR INSTALLATION: The ATP 8500 generates a certain amount of heat and requires ventilation. Do not place it  
on a soft surface such as a rug into which it could sink. You should also avoid a built-in installation place such as a  
bookcase or a rack unless you can provide proper ventilation for ATP 8500. Do not use this unit near water: for  
example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool. The unit  
should be situated away from heat sources such as radiators, heat registers, stoves, or other devices (including  
power amplifiers) that produce heat.  
WARNING: MOISTURE IS DANGEROUS FOR THIS DEVICE AND FORMS A HAZARD OF FIRE OR ELECTRIC  
SHOCK. IF LIQUID IS ACCIDENTALLY SPILLED ON IT, IMMEDIATELY SHUT OFF ITS POWER AT THE WALL  
OUTLET BY UNPLUGGING THE AC POWER CORD. ALLOW SUFFICIENT TIME FOR COMPLETE EVAPORATION  
BEFORE USING THE PREAMPLIFIER AGAIN. IF THE LIQUID IS ANY OTHER THAN WATER AND/OR  
ALCOHOL, DO NOT USE THE DEVICE BEFORE A QUALIFIED SERVICE TECHNICIAN HAS EXAMINED IT.  
DANGER: Do not open the cover, or try to modify or repair the preamplifier yourself. All servicing must be done by a  
qualified technician.  
IMPORTANT: USE A DAMP CLOTH TO CLEAN THE MONITOR. NEVER USE ABRASIVES OR SOLVENTS ON  
THE MONITOR. NEVER SPRAY LIQUIDS DIRECTLY ON THE MONITOR.  
Read all the safety and operating instructions before connecting or using this unit. All warnings on the unit and in this  
operating manual should be adhered to. All operating and use instructions should be followed.  
The unit should be connected to a power-supply outlet only of the voltage and frequency marked on its rear panel.  
The power-supply cord should be routed so that it is not likely to be walked on or pinched, especially near the plug,  
convenience receptacles, or where the cord exits from the unit. The power-supply cord of the unit should be unplugged  
from the wall outlet when it is to be unused for a long period of time. To prevent electric shock, do not use the polarized  
plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.  
The unit should be serviced by qualified service personnel when:  
A. The power cord or the plug has been damaged; or  
B. Objects have fallen, or liquid has been spilled, into the unit; or  
C. The unit has been exposed to rain, or liquids of any kind; or  
D. The unit does not appear to operate normally, or exhibits a marked change in performance; or  
E. The device has been dropped, or the enclosure damaged.  
Rack Mounting  
Your preamplifier-processor may be mounted in a standard 19-inch rack by using the optional Rack Mount Panel.  
CAUTION: THE RACK MOUNT PANEL CANNOT SUPPORT THE WEIGHT OF YOUR PREAMPLIFIER-  
PROCESSOR. BE SURE TO MOUNT THE UNIT ON A STRONG, WELL-SUPPORTED SHELF.

Quick Set-Up Guide  
PLEASE NOTE: WHEN USING THE REMOTE TO CONTROL THE ATP 8500 PREAMPLIFIER-PROCESSOR,  
YOU MUST FIRST PRESS THE “AVC” BUTTON IN THE UPPER LEFT CORNER OF THE REMOTE CONTROL .  
If you just can’t wait and want to get the ATP 8500 up and running as quickly as possible, here’s the quickest way:  
Connections  
1. Connect your power amp to the outputs (gold plated RCA connectors on upper right side) of the ATP 8500.  
The RR & LR outputs are for the additional 7.1 mode. Normally, you’ll just use the first 6 outputs for 5.1 operation.  
FYI, the RCA outputs and the XLR outputs can be used at the same time because they have separate driver electronics.  
Pin 2 is hot on the XLRs.  
2. Connect the composite video output  
of your VCR (normally the yellow  
colored jack) to the composite video  
input #1 (top row, left side).  
3. Connect the stereo audio outputs  
(red & white) of the VCR to the  
analog audio inputs #1  
(bottom row, left side).  
4. Connect the composite video output  
5-CHANNEL AMPLIFIER  
of the ATP 8500 (top row, just to the  
right of the 6 video input jacks) to  
the composite video input of your TV.  
You have two choices: use the output  
labeled “Mon OSD” (On Screen  
Display) if you want to the see the  
menu and status display on your TV.  
Use the output jack labeled MON if  
you don’t want to see the menu.  
Make certain your TV is set to  
monitor composite video input.  
5. Turn on the rear panel power  
switch of the ATP 8500.  
ATP 8500  
6. Turn on the power amp.  
7. Press the front panel power switch  
of the ATP 8500.  
8. Press “play” on the VCR.  
9. Press the “Input Search” button  
VCR  
TELEVISION  
on the front panel of the ATP 8500.  
This searches for any incoming signals, and will automatically find the source.  
If your VCR or DVD is not in play mode, the input search function will not see  
it because there is no incoming program signal.  
10.TURN UP THE VOLUME!

Input Assignment  
Want to get a little more sophisticated? Then add these steps to assign your VCR to a front panel input button:  
1. Go to Menu, go to Source setup, select input title VCR 1.  
2. Go to video, select composite video 1.  
3. Go to audio, select audio 1.  
4. Back out of the Menu by scrolling to EXIT (do not press the Exit button on the front panel or the remote control),  
and press enter.  
You’ve now assigned the VCR input to front panel button VCR 1.  
Digital Audio  
The next step up in complexity is to connect a DVD player with  
digital audio output so you can get 5.1 sound:  
1. Connect the composite video output of your DVD player (normally  
the yellow colored jack) to the composite video input #1 (top row,  
left side) of the ATP 8500, as you did with the VCR in at left.  
2. Connect the Toslink optical output of your DVD player to the  
DVD PLAYER  
Optical Input #1 on the rear of the ATP 8500 (top row, slightly  
right of mid-way). If you only have an SP/DIF digital audio  
connection (RCA type jack), use Digital Audio input #1.  
Warning: some DVD players have a switch on the rear panel  
to select the analog or digital audio outputs; make certain this  
is set to digital.  
Follow steps 4-10 in the first example.  
Component Video  
Want to use the component video output of your DVD player instead?  
1. Connect the 3 component video cables from your DVD player to  
ATP 8500  
the rear of the ATP 8500 marked Component Video Input #1.  
Make certain you follow the color coding of the cables or the labels  
Pb, Pr, and Y. Sometimes these are called Cb, Cr and Y instead.  
2. Connect the Component Video outputs of the ATP 8500 to the TV.  
Once again make certain you have the cables connected to the  
correct jacks.  
3. On your TV, select the component video input.  
4. Play a DVD with a Dolby Digital or DTS soundtrack.  
5. Press Input Search. If the component video in is not detected, you  
may need to go to the Menu system and tell the ATP 8500 to turn  
TELEVISION  
“on” these inputs. Go to Menu, go to Source Setup, select component video “on”. Now press Input Search again.  
Want to set the DVD to a front panel input? Follow the same steps as you did for the VCR assignment, except use the  
front panel button “DVD” and select the video source (composite/component/S-VHS) and the digital audio source.  
Remember to “back out” of the Menu by scrolling to the Exit selection.  
Now you’ve really got to read the manual to get any further. We suggest using an experienced installer to work with  
things like the trigger inputs and default settings.

Rear Panel Connections  
Power Connections  
(1) POWER INLET  
Before making any connections, check that the mains (AC) voltage or range of voltages printed on the rear panel is the  
same as your local mains supply voltage. Plug the female (socket) end of the power cord into the power inlet on the  
rear of the preamplifier. Plug the male (plug) end of the cord into a wall socket or an extension power cord.  
NOTE: CONNECT THE ATP 8500 ONLY TO A GROUNDED WALL SOCKET.  
(2) POWER SWITCH (REAR PANEL)  
Press the rocker switch to the “ I” position to turn the preamplifier ON and the “O” position to turn it OFF. In the OFF  
position, all power is disconnected from the preamplifier. In the OFF position, the ATP 8500 cannot be powered up from  
the front panel or the remote control. In the ON position (provided the device receives power from the wall outlet) the  
ATP 8500 will power up in standby mode (see FRONT PANEL CONTROLS, STANDBY). If you are not going to be using  
the ATP 8500 for an extended period of time, you should turn the rear panel "POWER" switch OFF.  
NOTE: ALWAYS SWITCH THE ATP 5800 TO “STANDBY”  
MODE (FRONT PANEL SWITCH OFF) BEFORE SWITCHING  
THE REAR PANEL POWER SWITCH OFF.

Audio Connections  
(3) ANALOG INPUTS 1 THROUGH 10  
Connect the output cables of the analog audio devices to these sockets. Always connect these inputs, even when you are  
going to listen only via digital inputs (such sources as DVD or CD players). This ensures that there is always a signal at  
the record outputs.  
The signal coming from the ANALOG audio inputs goes through an A/D converter that turns the analog signal into  
digital form (A/D=Analog to Digital. The signal is now ready for Dolby Pro Logic decoding or post-processing with  
Music Modes. Then the signal is fed to D/A converters and to 7.1 Channel outputs (D/A=Digital to Analog). The signal  
you have selected is also fed to the three ANALOG outputs. Note: the balanced stereo input (XLR connectors) can be  
routed via the menu system to bypass the A to D conversion and operate completely in the analog domain.

(4) TAPE INPUT/OUTPUT  
These connectors are for all types of tape recorders, including 3-head types, which allow you to monitor the signal from  
the tape at the same time it is being recorded. Connect a stereo cable pair from the TAPE REC output sockets of the preamp  
to the LINE IN or RECORD IN sockets of your tape recorder. Connect a second pair of stereo cables from the TAPE PLAY  
input sockets to the LINE OUT or PLAY OUT sockets of your tape recorder.Using the TAPE loop you can monitor the  
level and quality of the recording at the same time as the recording takes place. You can also use it for connecting  
external devices (such as an equalizer) to the signal path. Note: do not use an equalizer across the Tape Loop. Any ANALOG  
stereo source you have selected on the ATP 8500 will be automatically fed to the TAPE REC output sockets for recording.  
You cannot make a recording from a source that is connected ONLY to the digital inputs or the 7.1 channel inputs.  
(5) RECORD OUTPUTS 1 & 2  
The REC outputs carry the signal from the currently selected ANALOG stereo source device (except the source connected  
to the TAPE PLAY input or the 7.1 CHANNEL INPUT). You can connect these outputs to the inputs of any recording  
device. The signal can also be used in a multi-room set-up to feed power amplifiers in other rooms.  
(6) ZONE AUDIO OUTPUT  
This is an additional stereo output that is routed separately from the primary signal. In other words, you can watch  
one video/audio program in the living room, and send a different video/audio signal to the bedroom. Zone 2 sends a  
different source from the ATP 8500 to a power amplifier and a pair of loudspeakers that are located in another room.  
Note: the video signal follows this Zone 2 audio.  
(7) 7.1 CHANNEL INPUTS (LEFT FRONT, CENTER, RIGHT FRONT, LEFT SURROUND, RIGHT SURROUND,  
LEFT REAR, RIGHT REAR AND SUBWOOFER)  
Connect the audio inline outputs from any multi-channel analog source such as a Super Audio CD (SACD) player or a  
DVD-Audio player to these inputs by using up to eight interconnect cables (or four stereo cable pairs). The 7.1 CHANNEL  
inputs may be used with stereo, mono, 5.1 channel or 7.1 channel sources.  
You can also use these inputs as an “Analog Direct” input if you want to bypass the digital section of ATP 8500.  
Note: In this case you cannot use the record outputs.  
(8) 7.1 CHANNEL OUTPUTS (LEFT FRONT, CENTER, RIGHT FRONT, LEFT SURROUND, RIGHT SURROUND,  
LEFT REAR, RIGHT REAR AND SUBWOOFER)  
Connect these outputs to the line inputs of your power amplifiers. The SUB output is normally fed to the low-level Line  
Input of an active subwoofer. Alternatively it may feed a passive subwoofer with a separate power amplifier. These 7.1  
outputs are available at two different types of connectors:  
The deluxe RCA style phono jacks on the upper right of the rear panel.  
The balanced XLR connectors running across the center of the rear panel.  
Both connectors can be used at the same time because they have two completely separate drive amplifier sections.  
In fact, the balanced audio output circuitry of the ATP 8500 is superior to products costing 2-3 times more than the  
ATP 8500. As per professional audio standards, pin 2 of the output connector is “hot”. This is also true of the balanced  
XLR input connectors.  
The LEFT REAR (LR) and RIGHT REAR (RR) outputs are reserved for future surround formats. These outputs carry the  
analog signal that is fed to the LEFT REAR and RIGHT REAR 7.1 CHANNEL INPUTS<None> so that ATP 8500 can be  
used with an external 7.1 channel analog source connected to the 7.1 channel inputs. In the future it will be possible to  
fit the ATP 8500 with hardware/software capable of decoding 7.1 channel digital sources.

Video Connections  
(9) COMPOSITE VIDEO INPUTS 1 THROUGH 6  
These are the default video inputs. Connect the composite video output cables coming from your video sources to these  
inputs. Note: Take care to use inputs with the same name for the composite video, S-Video and analog audio cables  
from a single source. E.g. cables from a VCR (VideoCassette Recorder) should go to the VCR-VIDEO, VCR COMPOSITE  
VIDEO and VCR ANALOG inputs. The composite video signal is selected from these signals, and the signal is fed out  
from the COMPOSITE VIDEO record (REC) and monitor (MON) outputs. On Screen Display information is added to the  
MON output.  
(10) COMPOSITE VIDEO RECORD AND MONITOR OUTPUTS  
Connect the Composite Video input of your VCR to the COMPOSITE VIDEO REC output. Connect the Composite Video  
input of your display device (TV) to the COMPOSITE VIDEO MON output. The On Screen Display (OSD) information is  
present at this output. You can also use the COMPOSITE VIDEO MON output even if there is no composite video source  
connected. The S-Video signal you have selected is down-mixed to this output and you can use it for monitoring. Even  
on OSD video outputs, the OSD info can be turned off by going to the MENU function and selecting DISPLAY, then  
selecting OFF.  
(11) COMPOSITE VIDEO ZONE AND MONITOR OUTPUTS (MONITOR WITHOUT OSD)  
This is an additional Composite Video and Monitor output. You can use it for example to give a different signal to a TV  
located in another room called zone 2. On this Monitor output the On Screen Display (OSD) is not displayed.  
(12) S-VIDEO INPUTS 1 THROUGH 6  
Connect the S-Video output cables from your video sources to these inputs. Note: Take care to use inputs with the same  
name for the Composite Video, S-Video and analog audio cables from a single source. S-Video signals are of higher  
quality than Composite Video signals. So if you have a source device with S-Video outputs, we recommend you to use  
them, together with the S-Video inputs on your display. S-Video inputs are also automatically down-mixed to feed the  
Composite Video MON OSD output for displays that are without S-Video inputs.  
(13) S-VIDEO MONITOR OUTPUT (WITHOUT OSD)  
On this S-Video Monitor output, the On Screen Display (OSD) is not displayed.  
(14) S-VIDEO MONITOR OUTPUT (WITH OSD)  
On this S-Video Monitor output, the On Screen Display (OSD) is displayed, but you can switch it off by using the menu.  
(15) S-VIDEO RECORD OUTPUT  
Connect the S-Video input of your VCR to the S-VIDEO REC output. Connect the S-Video input of your display device  
(TV) to one of the two S-VIDEO MONITOR outputs (see items 13 and 14).  
(23) COMPONENT VIDEO INPUTS AND OUTPUTS  
Connect the three component video cables from your DVD player, HDTV tuner or HD Satellite Receiver to any of the  
three sets of Component Video Inputs. Make certain you follow the color coding of the jacks and cables or the labels  
Pb, Pr, and Y. Sometimes these are called Cb, Cr and Y instead. Connect the Component Video outputs of the ATP 8500  
to the Component Video inputs on your TV.

Connect the coaxial digital output cables from your source devices to these inputs. You can freely associate the digital  
inputs to any source (see menu option for further reference).  
(18) OPTICAL DIGITAL AUDIO INPUTS 1 & 2  
These connections require optical cables and connectors. You can freely associate the optical inputs to any audio source  
(see menu option for further reference).  
(16) OPTICAL DIGITAL AUDIO OUTPUT  
Connect the optical input of your digital recorder to the DIGITAL output. The selected primary digital source is fed to  
this output in optical format.  
Other Connections  
(19) BALANCED AUDIO INPUT  
This connection requires an XLR cable and  
connectors Pin 2 is “hot.”  
(20) RS 232 CONTROL INTERFACE  
Via this interface, you can connect the ATP 8500 to a home automation system. Contact your dealer for details.  
(21) IR INPUT/OUTPUT  
These connections are for an additional InfraRed remote controller.  
(22) REMOTE TRIGGER OUTPUTS 1 THROUGH 3  
You can connect the DC trigger inputs of any audio or other device to the TRIGGER outputs. The TRIGGER output may  
be activated when the ATP 8500 is switched out of STANDBY and immediately turned off again when the ATP 8500 is  
switched into STANDBY again. You can also program the TRIGGER outputs to be activated under other conditions (see  
menu section). The TRIGGER outputs deliver 12 VDC at a maximum total current (for the three outputs) of 200 mA.  
CAUTION: CONNECT OR DISCONNECT THE TRIGGERS ONLY WHEN THE POWER SWITCH IS OFF,  
OR THE UNIT IS DISCONNECTED FROM MAINS POWER!

Front Panel Controls  
POWER (STANDBY) SWITCH ON FRONT PANEL  
When you plug the ATP 8500 into a “live” mains power wall socket and turn the rear panel POWER switch ON, it will  
power up in “standby” mode. In this mode the internal circuit of the ATP 8500 is powered but inactive.  
When you press the front panel power button (which effectively functions as a “standby” switch), the ATP 8500  
circuitry is activated and the INPUT last used, the MODE last used, and the volume level (unless it was too loud) are  
automatically selected. The LINE outputs will be muted for a few seconds. If the volume is turned down and you are  
next to the ATP 8500, you may hear some slight “clicking” noises. This is normal, and the clicking noises you hear are  
from the switching relays. When you press the front panel power button again the device will return to standby mode  
and the LED above the power button will glow red again.  
NOTE: Always switch the ATP 8500 to STANDBY before switching the POWER OFF at the rear panel.  
DANGER: In the STANDBY mode, the internal circuitry is still “live”.  
Therefore, follow all safety precautions to prevent electric shock or fire!  
PREVIEW ON/OFF  
When you press this key once, the status of the ATP 8500 will be displayed on the OSD. The status display shows  
selected source, audio and video signal type, audio output type and volume information. The status display disappears  
after ten seconds or when you press the same key again. Note: There will be no status information if you have selected  
“Temp.Display-Off” from the OSD setup menu.

SOURCE SELECT ꢀꢀAND ꢀꢀ(UP AND DOWN)  
With these buttons you can browse up or down through the inputs to select the source (audio or audio-video) that is  
fed to the main outputs. The signal you have selected will also be fed to the TAPE REC output sockets for recording.  
The display shows the input you have selected. The SOURCE ꢀꢀand ꢀ buttons browse through all the sources except  
TAPE. You can select the 7.1 CHANNEL and TAPE inputs by the TAPE MONITOR and 7.1 CHANNEL input buttons. When  
you select an input, the ATP 8500 will automatically switch to the operating MODE last used with that input, or to the  
correct digital decoding if an active digital source is assigned to the input.  
DISPLAY  
To operate the display, use the “Preview” button on the front panel, or press “Guide” on the remote control.  
This function toggles on/off. The front panel video display has a number of modes:  
(1) When switching to a new input source, the display will show all major information about the selected input.  
For example, if you select DVD, the assigned video input will be listed in addition to the audio input, and surround  
sound mode.  
(2) When setting up the ATP 8500, use the display and the buttons on each side of the display to assign inputs and  
adjust the system parameters.  
(3) When adjusting the volume, the display will show the volume level for a short time, then automatically disappear.  
(4) The video display can be set to “off,” or only show the input video signal, or the display can be set to superimpose  
the parameters over the video source.  
(5) The style and color of the information on the display can be changed in the set-up menu. We suggest using modes  
1, 2, or 3 for general purposes.  
(6) The brightness of the display can be changed using the remote control. Each time you press the display button  
marked “Bright,” the brightness level changes.  
EXIT  
This key exits the setup mode without saving the new settings. Use it if you have adjusted the setup menu by accident.  
ENTER  
This is the enter key in setup mode. You can us it to access sub-menus or to activate special menu items.  
MENU  
When you press this key, the ATP 8500 goes to setup mode. Use the up/down/left/right keys to navigate the menus.  
The ATP 8500 escapes from setup mode when you either select EXIT from the OSD or press the MENU key again.  
VOLUME CONTROL  
With the volume control (the large, round knob in the upper right quadrant of the front panel), you can adjust the  
sound level of the signals that are fed to the LINE inputs. Note: The volume control does not affect the signals that are  
fed to the TAPE REC sockets, so you can adjust the listening volume level at the same time as recording takes place.  
The volume setting indication is situated in the bottom right of the LCD display, for example “vol: -15”. The display  
shows the preamplifier gain in dB (decibels). If you set the volume below –20, the ATP 8500 will remember this level  
when you switch it into STANDBY mode and will re-instate this same level when you switch the ATP 8500 on again.  
Note: If you switch the ATP 8500 into STANDBY mode with a volume setting higher than –20 dB, for example –10 dB,  
the ATP 8500 will automatically reset it to –20 dB when you switch it on again. This is to protect your ears and the  
loudspeakers from sudden excessive sound levels.

HEADPHONE VOLUME DOWN/UP AND HEADPHONE INPUT  
The up and down buttons control the headphone volume independently of the main volume. When adjusting the  
headphone volume, the OSD shows the relative difference (volume offset) compared to the main volume. It does not  
show the absolute level. All speakers will be turned off when a set of headphones are plugged in.  
SOURCE SELECT BUTTONS  
The buttons labeled DVD, Laserdisc, VCR 1, VCR 2, Satellite, Video 1, CD, Audio 2, Audio 3–AM/FM and Audio 4 can be used  
to directly access the audio and video sources. You can access all sources directly from these keys. For example, when  
you press the DVD key, DVD audio and video signals are selected and they are then processed and fed to the appropriate  
outputs for listening/viewing. Each of these inputs can be assigned to access whatever sources are connected.  
INPUT SEARCH  
Pressing this button searches all the inputs and stops on the first active input it sees. This is useful if you don’t know  
what sources are currently “on.”  
AUDIO MONITOR 1  
By pressing the AUDIO MONITOR 1 button, you can hear the output signal coming from a recorder connected to the  
TAPE PLAY sockets on the rear panel. The switch is of toggle type: When you press it once, it will engage and when you  
press it again, it will disengage. The TAPE MONITOR input also disengages if you select a new source from the front  
panel or from the remote handset. The AUDIO MONITOR 1 button has no effect on the other select buttons. The signal  
source you have selected with the SOURCE ꢀꢀand ꢀ buttons will be fed to the TAPE REC output sockets; whether the  
TAPE button is engaged or disengaged has no effect. If you have a three-head tape recorder that permits off-tape  
monitoring, you can use the TAPE button to compare the source signal to the off-tape signal. Thus you can check the  
level and the quality of the recording while the recording takes place. If you press the AUDIO MONITOR 1 button, it  
does not have any effect on the operating mode of the ATP 8500. The mode remains as currently selected. Note: If you  
engage the AUDIO MONITOR 1 button with no signal source connected to the TAPE PLAY, or with no tape running,  
you will hear only silence.  
ZONE 2  
Press the ZONE 2 button. Quickly, while the Zone 2 LED on the front panel is on, press a source button (DVD for  
example), then adjust the volume level. Now don’t touch anything until the Zone 2 LED goes off. You’ve now set a  
different source (or the same source if you prefer) AND volume level for a second zone.  
7.1 CHANNEL INPUT  
The 7.1 CHANNEL INPUT is intended for future multi-channel formats. When you press this button, it will access the  
7.1 CHANNEL INPUT. You may deselect it by changing the source using the SOURCE SELECTION buttons or by pressing  
the 7.1 CHANNEL INPUT button. In the latter case, the ATP 8500 will return to the input that was previously selected  
before the 7.1 CHANNEL button was pressed. In both cases, the similarly named buttons on the remote control handset  
function in exactly the same way (SRC+ , SRC– and 7.1 CH).  
MUTE  
When you press the MUTE key, it will engage mute mode and the ATP 8500’s line outputs will be muted. MUTE is a  
toggle function, so when you press the key again it will disengage the mute mode. Mute mode is also disengaged when  
you increase the volume setting by using the VOL ꢀ key on the remote handset.

Remote Control Handset Operations  
The remote control is preprogrammed to operate the ATP 8500 Digital Preamplifier-Processor in the AVC mode. It also  
has 7 other Device modes (accessed via the top two rows of buttons) including CD (CD player), DVD (DVD Player),  
AUX (auxillary), SAT (satellite), TV (television), VCR (videocassette recorder) and CBL (cable box) for learning functions  
from remote controls of other equipment from other manufacturers. A red backlight appears under the Device buttons  
when functions for that device are selected on the remote. The red light under the Device button is also used during  
programming and setting up the remote control. For instructions on learning new commands, turn to page 19.  
NOTE: The top left pushbutton on the remote labeled “AVC” must  
be selected before using the remote to operate the ATP 8500.  
POWER  
This key operates the same way as the STANDBY button on the front panel. It sends the command to switch the  
ATP 8500 into or out of standby mode.  
VOLUME ꢀꢀAND ꢀꢀ(UP AND DOWN)  
When you press the ꢀ key, you will increase volume setting, and when you press the ꢀ key, you will decrease volume  
setting. These keys work exactly the same way as the rotating volume control on the front panel. If the ATP 8500 is in  
the mute mode (after you have pressed the MUTE key on the handset), and you then press the VOLUME ꢀ key, the  
ATP 8500 will automatically disengage the mute mode and re-connect the signal to the power amplifier and the  
loudspeakers. This prevents an excessively high volume level from being set by mistake.  
CHANNEL ꢀꢀAND ꢀꢀ(UP AND DOWN)  
When in AVC mode (the top left button on the remote), these buttons scroll up and down the input selection.  
MUTE  
When you press the MUTE key on the remote handset, it will engage mute mode and the ATP 8500’s line outputs will  
be muted. MUTE is a toggle function, so when you press the key again it will disengage the mute mode. Mute mode is  
also disengaged when you increase the volume setting by using the VOL ꢀ key on the remote handset.  
GUIDE (same as PREVIEW on the front panel)  
When you press this key once, the status of the ATP 8500 will be displayed on the OSD. The status display shows  
selected source, audio and video signal type, audio output type and volume information. The status display disappears  
after ten seconds or when you press the same key again. Note: There will be no status information if you have selected  
“Temp.Display-Off” from the OSD setup menu.  
MENU  
When you press this key, the ATP 8500 goes to setup mode. Use the up/down/left/right keys to navigate the menus.  
The ATP 8500 escapes from setup mode when you either select EXIT from the OSD or press the MENU key again.  
EXIT  
This key exits the setup mode without saving the new settings. Use it if you have adjusted the setup menu by accident.  
SELECT/PLAY  
This is the enter key in setup mode. You can us it to access sub-menus or to activate special menu items.  
Page 16

ꢀ,ꢀ,ꢀ,ꢀ (UP, DOWN, LEFT, RIGHT KEYS)  
You can use these keys to navigate in the menu. The up and down keys are for  
selecting the parameter to be adjusted. The left and right keys are for adjusting  
the parameter you have selected with the up and down keys. The selected  
parameter is shown in the OSD with a different color and in the bottom row  
of the front panel display, or by an arrow in the beginning of the line.  
DIRECT ACCESS KEYS  
There are up to 16 direct access keys in the remote control handset. You can  
access all sources directly from these keys. For example, when you press the  
DVD key, DVD audio and video signals are selected and they are then  
processed and fed to the appropriate outputs for listening/viewing.  
TAPE MONITOR  
When you press the TAPE MON key, you can hear the output signal from a  
recorder connected to the TAPE PLAY sockets on the rear panel. This is a  
toggle function key: press it once to engage and again to disengage. The TAPE  
MONITOR input also disengages if you select a new source either from the  
remote control handset or from the front panel. When you press the TAPE  
MON key, it has no effect on the other source select keys.  
7.1 CH  
The 7.1 key operates in the same way as the 7.1 button on the front panel. It  
gives you instant access to select the 7.1 CHANNEL INPUT, which is deselected  
when the source is changed by using either the remote control handset or the  
front panel SOURCE SELECT buttons or by pressing the 7.1 CH key again.  
B-BASS (BASS MIX)  
This key switches on and off the Bass Mix mode. In this mode, the bass signals  
are sent both to the “Large” loudspeakers and to the subwoofer channel. This  
allows more bass volume, provided full range main loudspeakers are  
employed.  
COMP  
This key activates the Dolby Late Night function that compresses a Dolby  
Digital soundtrack so that all details are audible, even at low listening levels,  
but loud sounds are reduced in volume. Note: This function works only with  
Dolby Digital sources.

NOISE  
This key switches on the Noise Test signal, after the LEVEL key has been pressed or the level setup entered from the  
setup menu. A broadband noise is sent first to the Left Front Channel for a few seconds, the to the Center Channel and  
so on through the other channels. You can also use the level TRIM keys to adjust the level of any channel during this  
cycle (see below). While the level is being trimmed, the noise signal remains directed to that channel and it will only  
move to the next channel after the trimming has been completed.  
MODE+ AND MODE–  
These keys function in the same way as the MODE button on the front panel, but allow selection up and down through  
the available modes. You can use the MODE button to cycle through the Music Modes that are available when you select  
a 2-channel digital or analog source. The Modes are as follows: STEREO, MONO, PRO LOGIC and MUSIC and they are  
described in the table below. If you select a multi-channel digital source, the ATP 8500 will automatically use the most  
appropriate multi-channel processing format.  
SW+ AND SW–  
These keys function as the Subwoofer volume adjustment. If you have pressed LEVEL (or DELAY), then these keys are  
for trimming speaker levels of the LEVEL mode or speaker delays in the DELAY mode. First press LEVEL (or DELAY)  
and then trim by using these keys.  
CTR+ AND CTR–  
These keys adjust the level of the center channel speaker.  
SURR+ AND SURR–  
These keys adjust the volume of the surround speakers.  
BRIGHT  
This toggles between 3 levels of brightness of the front panel video display.  
LOCK  
Pressing this button locks the front panel of the ATP 8500 from use (the front panel controls won’t work). Pressing  
again unlocks the front panel controls. If you lose the remote, but have locked the front panel controls, simply turn off  
the ATP 8500 using the REAR panel power switch, and turn it back on again. The front panel controls will now operate.  
ZONE (same as ZONE 2 on the front panel)  
Press the ZONE button. Quickly, while the Zone 2 LED on the front panel is on, press a source button (DVD for  
example), then adjust the volume level. Now don’t touch anything until the Zone 2 LED goes off. You’ve now set a  
different source (or the same source if you prefer) AND volume level for a second zone.

• Setting the delay time on the center channel  
speaker helps align the sound of actor’s voices  
with the visual cues of their lips. For example,  
if the center speaker is located behind or in  
front of the video monitor, then the arrival  
of the sound will not match the movements  
on the screen.  
Exit  
AN EXAMPLE OF THE DELAY SETUP MENU  
You can calculate the delay times by first measuring the distance from the listening position to each speaker. At sea  
level, 1 foot equals approximately 1 millisecond (20 feet equals 20 milliseconds). Enter then these measurements in  
the table below. Place the Left and Right speakers at an equal distance from the listening position. Write the Left/Right  
Front speaker distance down three times, in each of the boxes in the top row.  
If you get the delay settings correct, the spatial perspective of the audio will be very good to excellent. If you get these  
wrong (especially the center channel), then the audio perspective will be inferior. One complication . . . humans have  
difficulty perceiving delays shorter than about 25-30 milliseconds. You may find that exaggerating the delay time  
makes the audio sound better to YOUR ears; or maybe not. Once you set the delay times by measurement, you might  
want to experiment with the time settings.  
The following example illustrates the calculation of correct delays. The Left and Right Front speakers are at 10 feet,  
the Center speaker is at 7 feet, the Left Surround and Right Surround speakers are at 13 feet from the listener.

for all the sources and provides a column to enter new names you have programmed.  
• When you select Digital, you may use the LEFT and RIGHT keys to select which of the six digital sources is assigned  
to the analog source being set up. You may assign a digital source to more than one analog source, if you so desire.  
• When you select “Analog sens.”, you may adjust the input gain of the Analog to Digital converter. You can set the gain  
to –6 dB, –3dB, 0dB or +3 dB. For CD players and other sources with a similar signal level we recommend either  
–6 dB or –3 dB. This is to ensure an adequate overload margin (typically 3 Vrms with –3 dB and 4 Vrms with –6 dB).  
Note: If the input has a lower level, you may set the input to be higher 0dB or +3 dB. This will result in a properly  
reduced level of background noise. If you hear distortion on loud signals with an analog source, re-select  
“Analog sens.” to a lower level.  
• “Preset” means one of the 5 tone control (EQ) presets. This can also be set to none. You can have different tone  
control presets for every input source.  
• EXIT returns to the main menu.

AN EXAMPLE OF THE TRIGGER SETUP MENU  
• “Polar” sets the polarity of the trigger output. “Posit.” gives a +12V DC output when trigger is active and +0V when  
inactive. “Negat.” gives +0V DC output when the trigger is active and +12V DC when the trigger is inactive.  
• “Delay” sets a delay between the “sense” signal and the trigger output voltage change. You may set the delay to last  
from 1 second to 3 minutes or to “No” position that gives zero delay.  
• “Durat" sets the period (duration) when the trigger output is active. You may set the trigger duration last from 10 ms  
(milliseconds) to 3 minutes, or to “Infin.” that keeps the trigger active while the “sense” condition prevails.  
• EXIT returns to the main menu.

Frequently Asked Questions  
How do I switch the on screen display (OSD) off?  
Go to Menu, go to Display Setup, go to OSD Output, select Off. Remember to exit by using the menu select buttons to  
exit, otherwise your changes will not register. Or use a different video output on the rear panel (not marked “OSD”)  
either S-Video or composite) if you never want the menu system to be seen on your TV.  
How do I get the OSD to superimpose the video?  
Go to Menu, go to Display Setup, go to Superimpose, select On. Remember to exit by using the menu select buttons to  
exit, otherwise your changes will not register.  
How do I change the color of the OSD?  
Go to Menu, go to Display Setup, go to OSD Style, select a number: 1-8.  
How do I route the balanced audio inputs to bypass the A/D converters?  
Go to Menu, go to Source Setup, go to Audio, select bypass. The bypass function only works with the stereo balanced  
inputs (XLR connectors).  
How do I see the video in the front panel LCD display?  
Press Preview button on the front panel.  
Why don’t the changes I make get memorized or stored?  
To save any changes you make in the menu system, you must “back out” of the menu system by scrolling to the “Exit”  
selection at the bottom of the menu display. Pressing “Exit” on the front panel or the remote will cancel any and all  
changes you've made.  
How do I assign an input signal to one of the front panel input selections?  
Go to Menu, go to Source Setup, go to Source and select the input for audio and video with the jog wheel on the front  
panel or the left/right buttons on the remote.  
When I press the “THX” button on the front panel (or other functions), nothing happens except for  
the words “future option” display at the bottom right of the screen.  
You probably have an earlier version of the hardware/software. Contact ATI to purchase upgrades, if available.  
How do I set the crossover frequency and what are your recommendations?  
Go to Menu, go to Speaker Setup, got to Sub Freq, and select one of the following:  
1–12” bass speaker = 60Hz 1–10” bass speaker = 70 Hz 1–6.5” bass driver = 80Hz  
1–5.25” bass driver = 120Hz  
Please consider this just a guide and experiment with the settings for the best sound in your room. You can also try  
selecting “Large” or “Small” speakers to affect the low frequency output.  
Why doesn’t the remote control power button turn on the ATP 8500?  
First, check batteries. Second, make certain the rear panel power switch on the ATP 8500 is turned on. Third, you must  
push the “AVC” button on the top row of the remote. This sets the remote to address the ATP 8500. The other buttons  
on the top row are for controlling your other equipment (DVD player, CD players, etc.). Then press the “power” button  
on the remote.

How do I hook up a DVD player?  
For component video, use the 3 wire video cables to connect the component video outputs of the DVD player to the #1  
component video input of the ATP 8500. Important: to view the component video input DVD signal from the ATP 8500,  
you must use the component video output of the ATP 8500 to the component video input of the TV or monitor. If your  
TV or monitor doesn’t have a component video input, then you must connect the DVD player to the S-Video or  
composite video inputs of the ATP 8500, not the component video outputs. Then use the composite video or S-Video  
outputs from the ATP 8500 to the same inputs on your TV or monitor. For digital audio, you need to connect the  
Toslink plastic optical cable from the DVD player to the ATP 8500 Toslink input #1. Otherwise, you won’t get Dolby  
Digital or DTS. If your DVD player has a BNC connector for the digital output or RCA-SP/DIF, then connect those to the  
same connector(s) on the rear of the ATP 8500. The Dolby Digital or DTS indicator LEDs will light automatically if they  
see the correct signal.  
I can’t see the video output of the ATP 8500 on my TV or monitor; what’s wrong?  
You need to make certain the video input used for the ATP 8500 is also the same video output, and it needs to be  
connected to the same input on your TV. For example, if you use the component video outputs of your DVD player to  
the ATP 8500, you must use the component video output of the ATP 8500 to the component video input of your TV, and  
you must use your TV remote (or master remote) to switch to the component video input.  
How do I change the title of a source?  
With the remote control, go to Menu, go to Source. When you select a source you may use the LEFT and RIGHT keys to  
select which one of the sources is to be set up. When you select a Title, you may edit the source Title, if you so desire.  
Press SEL and use the LEFT and RIGHT keys to choose the character you want to change, and the jog wheel (volume  
control knob) to change the character. When the editing is complete, press SEL to store the new name. FYI, the source  
number refers to the input the source is plugged into on the rear panel of the ATP 8500. But any source can be  
assigned an input name that shows up on the OSD. For example, input source 4 can be set with a title of “My VCR.”  
What’s the difference between Status screen and Preview mode?  
Status shows the input source, the volume level, and other info. Menu is used to change settings.  
Does the Status display always have to be visible?  
No way. You have two choices: no status display, or temporary display (displays status screen for about 10 seconds,  
then turns off). Go to Menu, Go to Display, select the mode you want. You can also set the Status to show only the input  
selected and the volume level.  
Is the OSD output available at the Component video outputs?  
No, just the S-Video and composite video outs. The character generator for the Menu and Status displays would reduce  
the resolution of the component video signal.  
How do I use the remote trigger from another room?  
You can get a repeater from a number of different manufacturers.  
How do I set up Zone 2?  
Press Zone 2 on the front panel. Quickly, while the Zone 2 LED is on, press a source button (VCR for example), then  
adjust the volume level. Now don’t touch anything until the Zone 2 LED goes off. You’ve now set a different source  
(or the same source if you prefer) AND volume level for a second zone. FYI, the record outputs to your VCR or tape deck  
only provide the source from Zone 1 or the primary source.

Trouble Shooting Guide  
CAUTION: If you detect a fault, switch the preamplifier OFF immediately before you check the device  
or change cables or connections.  
The remote control doesn’t work.  
• Check batteries  
• Make certain the rear panel power switch on the ATP 8500 is turned on.  
• You must push the “AVC” button on the top row of the remote. This sets the remote to address the ATP 8500.  
The other buttons on the top row are for controlling your other equipment (DVD player, CD players, etc.).  
Then press the “power” button on the remote.  
There is no sound.  
• The power cord is disconnected or you have turned the power OFF. Check whether the LED in the STANDBY button  
is illuminated.  
• You have selected an input with no source connected. Press the “Input Search” button on the front panel to  
automatically search for input signals.  
• You have selected an input that has no signal (e.g. tuner is not on, or there is no disc in the CD player or the tape  
recorder has no tape running).  
• The fuse is blown.  
• The Tape Monitor function is ON.  
• No 5.1 surround audio (video works, however) because you don’t have the digital audio output from the DVD player  
connected to one of the digital audio inputs (you probably just have the analog audio connected).  
The sound is missing in one or more channels.  
• There is a defective interconnect cable or cables.  
• If you’re using the XLR balanced inputs and/or outputs, make certain pin 2 is wired “hot.” Some products built in  
Asia (and even some built in the USA) use pin 3 as “hot.” Also, if you’re using #2 wire adapters to the 3 wire XLR,  
make certain pin 2 is wired correctly and pins 1 & 3 are tied together.  
• The interconnect cable is making poor contact or not connected at all. Check and if necessary unplug and replug the  
cable or cables.  
• You might be listening to stereo, not surround sound.  
I am hearing a buzz or hum.  
• The interconnect cable is defective.  
• The interconnect cable is partially out of its socket.  
There is hum during tape playback.  
• The tape deck is too close to the power amplifier.  
• Plugs are making poor contact with sockets.  
Some functions are not working.  
• The control processor is latched. Switch POWER off (rear panel power switch) and wait for about a minute. Switch  
POWER on. The ATP 8500 should now operate normally.
