Plug Fitting Instructions (UK Only)
NOTE: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR
TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO
THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER
AUTHORITY TO OPERATE THE EQUIPMENT.
The cord supplied with this appliance is factory fitted with a UK mains plug
fitted with a 5 amp fuse inside. If it is necessary to change the fuse, it is
important that a 5 amp one is used. If the plug needs to be changed because
it is not suitable for your socket, or becomes damaged, it should be cut off
and an appropriate plug fitted following the wiring instructions below. The
plug must then be disposed of safely, as insertion into a mains socket is likely
to cause an electrical hazard. Should it be necessary to fit a 3-pin BS mains
plug to the power cord the wires should be fitted as shown in this diagram.
The colours of the wires in the mains lead of this appliance may not
correspond with the coloured markings identifying the terminals in your plug.
Connect them as follows:
This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation.
The wire which is coloured BLUE must be
connected to the terminal which is marked
with the letter ‘N’ or coloured BLACK.
If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or
more of the following measures:
The wire which is coloured BROWN must be
connected to the terminal which is marked
with the letter ‘L’ or coloured RED.
- Re-orient or relocate the receiving antenna.
The wire which is coloured GREEN/YELLOW
must be connected to the terminal which is
marked with the letter ‘E’ or coloured GREEN.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
If your model does not have an earth wire, then disregard this instruction.
If a standard 13 amp (BS 1363) plug is used, a 5 amp fuse must be fitted,
or if any other type of plug is used a 5 amp fuse must be fitted, either in the
plug or adaptor, or on the distribution board.
- Consult the dealer or an experienced radio/TV technician for help.

Important safety instructions
Please take a moment to read these notes before installing your 340R,
as they will enable you to get the best performance and prolong the life
of the unit. We advise you follow all instructions, heed all warnings and
keep the instructions for future reference.
Overloading
Do not overload wall outlets or extension cord as this can result in a risk
of fire or electric shock. Overloaded AC outlets, extension cords, frayed
power cords, damaged or cracked wire insulation, and broken plugs are
dangerous. They may result in a shock or fire hazard.
Ventilation
IMPORTANT - The unit will become hot when in use.
Lightning
For added protection during a thunderstorm, or when it is left
unattended and unused for long period of time, unplug the unit from the
wall outlet and disconnect the antenna or cable system. This will prevent
damage to the unit from lightning and power-line surges.
Please ensure there is ample ventilation (at least 10cm clearance all
round). Do not put any objects on top of this unit. Do not situate it on a
rug or other soft surface and do not obstruct any air inlets or outlet
grilles. Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers) that produce
heat. Do not stack multiple units on top of each other. Do not place in
an enclosed area such as a bookcase or in a cabinet without sufficient
ventilation.
Outdoor antenna grounding
If an outside antenna or cable system is connected to the product, be
sure the antenna or cable system is grounded so as to provide some
protection against voltage surges and built-up static charges. Section
810 of the National Electrical Code, ANSI/NIPA No. 70-1984 (section 54
of Canadian Electrical Code, Part 1) provides information with respect to
proper grounding of the mast and supporting structure, grounding of the
lead-in wire to an antenna-discharge unit, size of grounding conductors,
location of antenna-discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
Do not obstruct the rear heat tunnel ventilation grille. Ensure that small
objects do not fall through any ventilation grille. If this happens, switch
off immediately, disconnect from the mains supply and contact your
dealer for advice.
Positioning
Choose the installation location carefully. Avoid placing it in direct
sunlight or close to a source of heat. Also avoid locations subject to
vibration and excessive dust, cold or moisture. Do not place the unit on
an unstable surface or shelf. The unit may fall, causing serious injury to
a child or adult as well as serious damage to the product. Do not place
other equipment on top of the unit.
Cleaning
To clean the unit, wipe its case with a dry, lint-free cloth. Do not use any
cleaning fluids containing alcohol, ammonia or abrasives. Do not spray
an aerosol at or near the amplifier.
This unit must be installed on a sturdy, level surface. Do not
place in a sealed area such as a bookcase or in a cabinet. Any
space open at the back (such as a dedicated equipment rack)
is fine however. When a cart is used, use caution when moving
the cart to avoid injury from tip-over.
Attachments
Do not use attachments not recommended by your dealer as they may
cause harm to the unit. Only use the specified attachments/accessories
with this unit.
WARNING - To reduce the risk of fire or electric shock, do not expose this
unit to rain or moisture. This unit must not be used near water or
exposed to dripping or splashing water or other liquids. No objects filled
with liquid, such as vases, shall be placed on the unit. In the event,
switch off immediately, disconnect from the mains supply and contact
your dealer for advice.
Servicing
These units are not user serviceable, never attempt to repair,
disassemble or reconstruct the unit if there seems to be a problem. A
serious electric shock could result if this precautionary measure is
ignored. In the event of a problem or failure, please contact your dealer.
Contact the service department should any of these conditions occur:
- When the power-supply cord or plug is damaged.
Electronic audio components have a running in period of around a week
(if used several hours per day). This will allow the new components to
settle down, the sonic properties will improve over this time.
- If liquid has been spilled, or objects have fallen into the amp.
- If the unit has been exposed to rain or water.
Grounding and polarisation
Do not defeat the safety purpose of the polarized or grounding type plug.
A polarized plug has two blades with one wider than the other. A
grounding type plug has two blades and a third grounding prong. The
wide blade or third prong are provided for your safety. If the provided
plug does not fit your outlet, consult an electrician for replacement of
the obsolete outlet.
- If the unit does not operate normally after following the operation
instructions, adjust only those controls that are covered by the
operation instructions.
- If the unit has been dropped or damaged in any way.
- When the unit exhibits a distinct negative change in performance.
Power sources
IMPORTANT
The unit should be operated only from the type of power source
indicated on the marking label. If you are not sure of the type of power-
supply to your home, consult your product dealer or local Power
Company.
If the unit is run at a very high level, a sensor will detect a temperature
rise and show "PROTECTION OVERLOAD" on the display. The unit will
then go into Standby mode. It cannot be switched on again until the
temperature has fallen to a more normal level.
This unit has been designed to be left in Standby mode when not in use,
this will increase the life of the amplifier (this is true with all electronic
equipment). To turn the unit off completely switch off on the rear panel.
If you do not intend to use this unit for a long period of time, unplug it
from the mains socket.
Power cord protection
The unit must be installed in a manner that makes disconnection of the
mains plug from the mains socket outlet (or appliance connector from the
rear of the unit) possible. Where the mains plug is used as the disconnect
device, the disconnect device shall remain readily operable. Protect the
power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the unit.
Be sure to insert each power cord securely. To prevent hum and noise, do
not bundle the interconnect leads with the power cord or speaker leads.

around until you get the best reception. For continued use, we strongly
recommended using a 75ohm outdoor FM aerial.
Connect to source equipment using stereo phono cables (stereo 2RCA-
2RCA). Tape/MD/CDR recorder/players require two sets of stereo
phono/RCA cables, one for recording, one for listening.

Connect each end of the single length antenna to the antenna
terminals. Place the antenna as far from the main system as possible to
prevent unwanted noise and to obtain optimum reception. If the AM loop
aerial provided does not receive sufficient reception, it may be
necessary to use an outdoor AM aerial.

HDMI connections
HDMI (High-Definition Multi-Media Interface) is an all digital connection
that can carry both audio and video in one cable. Direct digital transfer
of video and support for various types of High Definition video content
make this the best connection type for picture quality. The two HDMI
inputs can be assigned to any one of the DVD, Video 1, Video 2, CD/Aux,
Tape/MD and 5.1 Direct inputs (see the ‘Assigning HDMI sources’
section of this manual for more information).
The sources will also normally supply audio to the TV/Monitor over the
HDMI connection, this will be separate from the audio that the 340R
decodes.
In order for the 340R itself to receive audio (Including surround-sound)
from HDMI (or DVI) sources a Co-axial (SPDIF) or Optical (Toslink) digital
audio connection must be made from each source to the 340R.
DVI switching can be supported simply by using DVI to HDMI adaptors as
these two connection types are compatible. When using DVI only video will
be passed to the TV/Monitor. Again a Co-axial (SPDIF) or Optical (Toslink)
digital audio connection must be made from each source to the 340R for
it to be able to receive audio and decode surround sound etc.
The 340R routes the HDMI outputs of DVD players, set-top boxes etc to
the TV/Monitor without any internal processing. Consult both the source
and TV's manuals to find out how to set the best modes for best picture
quality. As the 340R only routes/switches HDMI it is not involved in
these settings itself.

340R setup
The setup of the 340R is a 5 stage process as follows:
1. Speaker configuration.
2. Speaker delay
To setup your speaker configuration, press the OSD button on the
remote to activate the On-Screen Display (OSD). Note: You must be
connected to a TV/Monitor by Composite or S-Video connections first.
Highlight the ‘Speaker Configuration’ menu by using the Volume
Up/Down buttons on the remote and press the Enter button:

‘Large’ or ‘Small’ are used to describe each speaker in terms of bass
response, they do not necessarily reflect the actual physical size of the
speaker.
Large = Speakers with an extended low frequency response of
approximately 20-40Hz to 16-20kHz (floorstanders or high quality larger
stand-mounted speakers).
1
Front Left and Right speakers
For stereo and multi-channel sound.
Small = Speakers with a less extended low frequency response of
approximately 80-100Hz to 16-20kHz (small stand-mounted, bookshelf
or satellite speakers).
2
Centre speaker
For dialogue and centre sounds. Ideally position at a similar height to the
front left and right speakers (above or below the TV/monitor). Using a
centre speaker from the same manufacturer/range as used for the front
left and right speakers is advisable. This ‘timbre matching’ allows
surround effects to flow more naturally from left to right without obvious
transitions between the speakers.
Setting each speaker allows the 340R to perform what is called Bass
Management and to direct low frequency bass from music and the Low
Frequency Effects channel of surround sound material to those
speakers best able to reproduce it. If you do not wish to use any of the
speakers change it’s setting to ‘None’.
3
Surround Left and Right speakers
The Subwoofer output can also be set to ‘Yes’ or ‘No’. If no sub is being
used make sure this setting is set to ‘No’ to allow the 340R to re-direct
the bass information in this channel to other speakers.
For ambient and multi-channel sound. Floorstanding speakers should be
angled towards the listening position. Bookshelf/standmount speakers
should be wall mounted or used with dedicated speaker stands,
positioned at or above ear height.
Note: The 340R will force some speakers to certain settings in some of
the following circumstances!
4
Subwoofer
The Front Left and Right speakers may be ‘Large’ or ‘Small’ but never
‘None’ as they are always required for any type of music/movie
reproduction.
For improving the bass in your system, as well as reproducing dedicated
LFE cinema effects when playing Dolby Digital or DTS encoded discs.
Your subwoofer can often be placed almost anywhere in the room as
bass is less directional, but experimentation with positioning is
recommended.
Bass must always be reproduced by either the Front Left and Right or
Subwoofer channel (or both). The 340R will thus not allow a
combination of ‘Small’ front speakers and no subwoofer.
If the Front Left and Right cannot reproduce low frequency bass a
Subwoofer must be used i.e. If the Front Left and Right are set as ‘Small’
the Sub must be Set to ‘Yes’.
The 5.1 relates to the maximum number of speakers that can be used,
as the Centre, Sub and Surround speakers can all be deleted if required
(although of course performance is reduced). For example, if you choose
not to use a Centre Channel speaker you can set this to ‘None’ in the
settings as shown later and the 340R will automatically redirect the
centre channel audio information into the Left and Right Front channels,
creating what is known as a ‘Phantom Centre’.
Also, setting the Front Left and Right as ‘Small’ will always set the other
speakers as ‘Small’ (and the Sub to ‘Yes’). This is because LFE/ bass
information should not be redirected to the surround channels.
To store the setting simply come back out of the OSD (pressing the OSD
button always moves back one menu item, and then exits and stores
from the main menu screen).
Similarly, you might decide not to use a subwoofer if your main Left and
Right speakers are capable of reproducing enough bass for a satisfying
music/movie experience. The 340R will then automatically re-direct the
bass from the Subwoofer/Low Frequency Effect channel to the Left and
Right Front Speakers.

azur 340R
2. Speaker delay
3. Level calibration
Because the speakers in a surround sound system are usually different
distances from the listener the 340R incorporates the ability to apply a
variable digital delay to each of the channels so that the sound from
each arrives at the same time at the listening position for best surround-
sound effect. Each pair of speakers (i.e. Front Left and Right or Surround
Left and Right) are subject to the same delay and so must be situated
equidistant from the listener.
The 340R allows level calibration to match the acoustic level between
different types/sizes or even manufacturers of speaker that may be
being used for each channel. This is achieved by adjusting the relative
level of each speaker through the ‘Level Calibration’ menu in the OSD.
The basic process is to listen to or measure with an SPL meter (more
accurate and recommended but not essential) the level of sound
produced by each speaker and set relative levels for each speaker so
that they all sound the same loudness at the normal listening position.
The 340R incorporates a Test Signal Generator (broad-band white noise)
to facilitate this.
To set the delay times simply measure the distances from the listening
position to each speaker as shown in the following diagram:
1
Set the unit to a normal listening level or half maximum volume
approximately. Press the OSD button on the remote control then select
the ‘Level Calibration’ menu. Now turn on the test signal by highlighting
this item and pressing the Left or Right arrows:

Return To Menu
: [OSD]
Note: No delay setting for the subwoofer is necessary.
Set the distances in the OSD Speaker Delay menu to the nearest value
in metres (1 foot = 0.3 metres). The speed of sound is approx 340
metres per second, the 340R thus introduces approx 3mS of delay per
metre of distance set.
A “rushing” or “hissy” sound should be heard, initially through the Front
Left Speaker.
You can now move up and down the channels using Volume Up/Down
on the remote. Each time a new channel is selected the test signal will
be heard to move to that channel. Compare the loudness of all channels
as heard at the listening position.
Go to the ‘Speaker Delay Menu’ and highlight each speaker in turn. Set
the distance to the nearest value to that which you measured by using
the Left and Right arrows (the values do not need to be exact):

Return To Menu
: [OSD]
Press the OSD button to exit the menu.
Note: In addition to the delays as set above Dolby Pro Logic II playback
also requires an extra 15 milliseconds delay to the surround channels
only. This extra delay is part of the Dolby Pro Logic II specification and
ensures that sound from the surrounds arrives just after sound from the
front reducing the audibility of sound leakage from the front to the
surround speakers. Because the relationship between the Dolby Digital
and Dolby Pro Logic II two delays is fixed (15mS extra to the surround
channels), it is only necessary to set the delay by measuring the
distances as we have described. The 340R will automatically provide the
appropriate extra delay whenever you switch to a Pro Logic Mode.
Now adjust the channels so they all sound the same (in terms of
loudness only, channels of different frequency responses can sound
different in terms of the “tone” of the sound i.e. more or less hissy).
Pick the channel that sounds most different and select it to listen to the
test signal. Now adjust the relative level in dB (using Arrow left/right on
the remote) and continue comparing it to other channels until it is of
equal loudness. The level can be adjusted up to + or - 10dB in 1dB
steps. Repeat the process with the next loudest channel etc. Once all
channels sound the same in terms of loudness, press the OSD button
again to save the settings and exit the menu.

4. Source setup
5. Assigning video sources
The next step is to select each source input in turn on the 340R and tell
the unit the type of audio connection you want to use for that source
(Analog or Digital input).
All of the 340R’s rear panel video inputs (S-Video/Composite,
Component and HDMI) are freely assignable to the DVD, Video 1, Video
2, Tape/MD, CD/Aux and 5.1 Direct sources for maximum flexibility.
The 340R remembers this setting individually for every source input and
automatically recalls it as and when you change source input.
Select the ‘Input Assign’ menu. Highlight each Video input in turn and
select a source to assign it to:

Note: The 340R prevents you from setting two sources to the same
video input, as this would cause problems, but doesn’t prevent you from
setting the same source to different video inputs.
Return To Menu
: [OSD]
Analog inputs will require a stereo phono/RCA to phono/RCA cable
connection to the 340R. Digital inputs will require either a 75ohm digital
type phono/RCA to phono/RCA co-axial cable (SPDIF) or an optical fibre
cable (TOSLINK). The 340R will automatically use whichever is
connected. Do not make connections to both the Optical and Co-axial
inputs for a source.
The 340R has two HMDI (High Definition Multi-Media Interface) inputs
and one HDMI output. HDMI is a fully digital audio/video system that
passes the picture and audio to the screen in digital format for best
possible picture quality. DVI (Digital Video Interface) is a subset of HDMI
that uses different connectors and only passes digital video to the
TV/Monitor (no audio). The 340R is fully compatible with DVI in that
simple passive DVI-HDMI adaptors are available which allow the
conversion of the DVI connector to an HDMI format connector (and back
again if required) for routing via the 340R. The 340R can switch both
types of signal.
Note: Video 3, Tuner, Tape and 5.1 Direct only have analog connections
and so are not selectable in this menu.
Once you have set the audio types exit the OSD to save.
This setting can also be changed at any time without using the OSD by
pressing the Input Mode button on the front panel (or Audio Type button
on the remote). This will then cycle between analog or digital input types
for the currently selected source; as usual they will then be remembered
the next time you return to that source.
The 340R performs HDMI switching, not processing, it routes the HDMI
signals from the source equipment to the TV/Monitor without any
processing, so as far as the 340R is concerned there is no setup
involved other than to assign the three inputs to a desired source. The
340R does not receive audio or video over the HDMI, so for surround-
sound decoding etc, an audio connection must also be made from your
HDMI source to the 340R. As with other sources this can be analog or
digital audio. A digital audio SPDIF/Toslink connection is preferred and
will be required if it is desired to decode surround-sound for the HDMI
sources.
Press the OSD button to exit the menu.
HDMI Pre-Emphasis
The HDMI interface is generally specified for transmission over cable
lengths up to 5m. Longer cable runs can sometimes be accommodated
if very high quality HDMI cables are used. The 340R is able to apply
some pre-emphasis to the HDMI signals to allow for cable losses in such
situations. For cable runs less than 5m HDMI Pre Emphasis should
generally be ‘Off’. For runs greater than 5m HDMI Pre Emphasis should
be ‘On’.
Note: The maximum cable length possible depends on cable quality and
to some extent on the resolution of the video being transmitted (i.e.
higher bit rate signals are harder to transmit over long distances). Use
only good quality HDMI cables. Poor quality cables can have problems
with HDMI at only 5m and only very high quality cables will work at
distances over 5m.
Select the ‘Output Setup’ menu, highlight ‘HDMI PRE’ and select either
‘Off’ or ‘On’:

azur 340R
Surround sound modes
The 340R has several music and home-cinema listening modes
available. Before we describe how to operate the 340R, below is a brief
guide to surround sound formats:
Dolby Digital
Known also as DD (3/2) or DD 5.1, provides (up to) 5.1 output from
suitable encoded Dolby Digital material, with 5 main channels (Front
Left, Front Right, Centre, Surround Left, Surround Right) and a Low
Frequency Effects Channel for the subwoofer, all discretely encoded.
Decoding Dolby Digital requires a Dolby Digital encoded DVD disc and a
digital connection from the source equipment (Such as a DVD player) to
the 340R.
Note: Dolby Digital and DTS formats can sometimes carry less channels
than their maximum such as Dolby Digital (2/0) which means a Dolby
Digital encoded signal which is actually only carrying a two channel
stereo signal (other channels inactive).
DTS
Known also as DTS (3/2) or DTS 5.1, DTS provides (up to) 5.1 output
from suitable encoded DTS material, with 5 main channels (Front Left,
Front Right, Centre, Surround Left, Surround Right) and a Low Frequency
Effects Channel for the subwoofer, all discretely encoded. Decoding DTS
requires a suitably encoded DTS disc and a digital connection from the
source equipment to the 340R.
Pro Logic II
The replacement for original Pro Logic, Pro Logic II is a technology where
5 channels (Front Left, Front Right, Centre, Surround Left, Surround
Right) are encoded into a Stereo mix by an analog matrix process. Dolby
Pro Logic II material can be played back by normal Stereo equipment (as
Stereo) or decoded into 5 channel surround-sound.
Dolby Pro Logic II is compatible with the earlier 4 channel (Left, Centre,
Right and mono Surround) Dolby Pro Logic system (which was the
decoding counterpart to Dolby Surround encoding) as used widely on
Video tapes, TV broadcasts and earlier films.
Note: Pro Logic does not include a Low Frequency Effects channel for
the Subwoofer, but the 340R can create a Subwoofer output (for 5.1) via
Bass management. Refer to the ‘Advanced bass management’ section
in the ‘Operating instructions’ part of this manual.
Dolby Digital EX
Known also as DD (3/3) or DD 6.1, an enhanced form of Dolby Digital.
On top of the normal discretely encoded 5.1 channels DD EX provides an
extra 6th channel (Surround Back) matrix encoded into the rear
surrounds. As DD EX 6.1 is backwards compatible with DD 5.1 the 340R
can play back DD EX material as 5.1. The 6th Surround Back signal is
then present in both Left and Right Rear Surrounds forming a phantom
rear centre.
DTS-ES 6.1 Matrix, DTS-ES 6.1 Discrete
Enhanced forms of DTS which also encode an extra 6th channel
(Surround Back) into the rear surrounds. Both DTS EX Matrix and DTS EX
Discrete are backwards compatible with DTS 5.1 so the 340R can play
back DTS ES Matrix or Discrete material as 5.1, the 6th Surround Back
signal being present in both Left and Right Rear Surrounds as a
phantom rear centre.
DSP modes
These modes allow a realistic surround-sound experience from source
material that has no encoding at all. The surround sound effect is
achieved by Digital Signal Processing of the Analog or Digital stereo
source used. Five modes are possible: Movie, Music, Room, Theatre and
Hall.

If no button is pressed for 4 or 5 seconds the 340R returns to normal
operation without changing mode.
Stereo Modes - Selects 2 channel Stereo operation for stereo material,
pressing again selects Stereo + Sub mode.
This is a digitally processed mode that allows bass and treble controls,
and sub generation if required. The input can be either analog (in which
case it will be turned into digital by 24 bit A/D conversion) or natively
digital.
Digital inputs can be connected to the SPDIF outputs from Tuner's or CD
Players etc (LPCM) or the digital outputs of DVD players (set to
Bitstream/Raw) playing 2-channel Dolby Digital (2/0) or DTS (2/0)
material.
Pro Logic II - Selects Pro Logic II decoding for use with appropriate matrix
encoded material.
Dolby Digital / DTS Modes - Selects a range of digital surround modes
with the appropriately digitally encoded material (only). These modes
are for use with the digital outputs (set to Bitstream/Raw) from DVD
players or satellite receivers etc. In order for the 340R to allow selection
of these modes a valid input digital bitstream must be present. This is
because the 340R needs to read the incoming flags in order to
determine the type of decoding which can be used and present any
options that might be possible.
If no bitstream is present, pressing this button will result in the 340R
displaying ‘MODE UNAVAILABLE’.
Incoming Dolby Digital/DTS streams are always shown on the front
panel display as Dolby Digital (x/x) or DTS (x/x), where the bracketed
numbers indicate the active channels in the source material. Active
output channels are shown by the icons on the right hand side of the
front panel display. Possible incoming DD/DTS types are:

Dynamic Range Control
This setting controls the dynamic range of Dolby Digital or DTS movie
soundtracks by compressing the dynamics in four stages to limit the
difference in level between loud and quiet passages in the movie.
Radio Data Systems (RDS)
RDS is a method for the transmission of additional information from
local radio stations. It is only available in FM mode. RDS will only work if
the local broadcasting stations have RDS transmission and the signal is
strong enough.
This can be a useful feature when watching movies late at night for
instance. Four settings are possible:
Press the Display button on the remote and go through the displayed
functions. There are functions for PS, PTY, CT and RT:
DRC=0/4 No Compression (normal full dynamic range playback)
PS (Station Name) - current station name will be shown
DRC=1/4
PTY (Program Type) - current name type of the program will be shown
CT (Clock/Time) - current time from Radio Station will be displayed.
DRC=2/4
DRC=3/4
Note: Clock/Time will be only transmitted from local radio station once
a minute. If the Clock - Time is not available the message ‘NO CT’ will
appear briefly on the display.
DRC=4/4 Greatest Compression (reduced dynamic range playback)
DRC can be accessed by the DRC button on the remote, DRC=0/4 etc is
displayed, pressing the button again moves to the next setting. When
finished make no adjustment for a few seconds and the 340R will save
the settings and exit the menu.

Audio split mode
The 340R is able to allow the user to listen to one source whilst viewing
another. For instance this can be useful if it is desired to watch a sports
channel from say a set-top/satellite video source whilst getting audio
commentary from the Radio Tuner. Another example might be to listen
to a CD whilst watching a video channel, perhaps waiting for a TV
programme to start.
Note: These adjustments work in the digitally processed Stereo and
Surround modes but not in 5.1 Direct mode.
The Sub/LFE channel (for DD / DTS material) can also be trimmed by up
to -10dB in 1dB steps useful for late night listening or other situations
where it might be desired to reduce the low frequency effect level
perhaps temporarily.
First select the Video channel you wish to watch in the normal way. Now
press and hold down the button for the channel you wish to listen to.
After 4 seconds approx ‘Audio Split’ will scroll across the display and you
will now be listening to the other source.
LFE Trim adjustments can also be made from the remote without the
OSD by pressing the LFE Trim button and using the Vol Up/Down
buttons.
To cancel audio split mode simply select a new source and normal
operation will be resumed.
Advanced bass management
The 340R also features an advanced bass management system which
when turned on allows the user to set different crossover frequencies for
different modes of operation, plus a special Bass Augment function.

Off
In normal operation (Bass Augment Off) if the Front speakers are set to
‘Small’ (in the ‘Speaker Config’ menu) their bass is re-directed by high-
pass filtering the Fronts and sending that bass to the Sub channel (i.e.
bass is removed from the Fronts and sent to the Sub). If they are set to
‘Large’ no filtering takes place and no bass is sent from them to the Sub
channel.
Return To Menu
: [OSD]
The crossover adjustment in the Sub Setup menu is used to determine
the point as which this transition is made. In other words it sets the
frequency below which bass is routed away from any ‘Small’ speakers
and into the Subwoofer channel. It should be understood that bass sent
to the subwoofer by bass management is different to bass encoded into
the surround-sound material as a dedicated Low Frequency Effects
channel. The crossover point can be adjusted from 40Hz to 150Hz in
10Hz steps.
However with the Bass Augment function On and the Front speakers set
to ‘Large’, bass from the Front Left and Right is now sent to the Sub
channel without any filtering of the Front Left and Right taking place (i.e.
these channels remain full range). In other words, the bass in the Sub
channel is augmented by extra bass from the Front Left and Right
channels. If the Front Left and Right are set ‘Small’, Bass Augment has
no effect and operation is the same as for Bass Augment Off.
Bass Augment can be On or Off separately for DD/DTS or PLII operation.
If the source material contains a separate LFE channel (ie DD or DTS
material) this is always routed to the subwoofer (if it is On) and is not
affected by the crossover setting. Note: Pro Logic II does not actually
have a LFE channel.
There is no Sub Augment function for Stereo + Sub mode because in
this mode if the Front speakers are set to ‘Large’ they will actually always
be unfiltered.

Advanced bass management continued
Custom installation (C.I.) use
IR Emitter
Bass Augment can be a useful function with PLII material because this
encoding type does not include an LFE Channel. This would normally
mean that if all the speakers in your setup were set to ‘Large’, the
subwoofer would in fact be inactive (as no bass has been re-directed
plus there is no LFE channel). If it is desired to have the subwoofer
running with all Large Speakers and PLII encoding, enable Bass
Augment for PLII and then set the Crossover point and level by ear. A Sub
channel will now be created from the Front Left and Right channels
without filtering them. As with all adjustments it is a good idea to
experiment to determine what works best with your particular setup.
The 340R features an IR Emitter input that allows
modulated IR remote control commands to be received
In
electrically by the unit. These control commands are
typically generated by custom installation (multi-room)
systems or remote IR receiver systems. An RS232 port is
also featured which allows the 340R to be controlled by C.I.
systems.
RS232C
In addition the 340R features ‘direct’ IR/Control codes as well as toggle
codes for many of their features to simplify programming custom
installation systems. Special direct On/Off commands can be accessed
on the supplied remote control for teaching into C.I. systems as follows:
Note: In Advanced Sub On mode, the Subwoofer level control in the ‘Level
Calibration’ menu will be inactive. This is because this setting is
overwritten by the three appropriate Sub Trim settings from the ‘Advanced
Sub’ menu.
1. Press and hold the Standby/On button on the remote control. The
remote first generates it's standby (toggle) command. Keep the
button held down, after 12 seconds an AV receiver ‘On’ command will
be generated. If the button is kept held down for a further 12
seconds, an AV receiver ‘Off’ command is generated.
Repeat this procedure with the Mute, Sub On/Off, Stereo Mono and
Tuner FM/AM buttons to send On/Off commands. The Tuner FM/AM
button also provides unique FM and AM commands to allow switching to
a specific band.
