AVR280
Before you start!
Introduction
The AVR280 is a high quality and high performance home cinema processor and multi-channel audio
amplifier built to Arcam’s traditional high quality design and manufacturing standards. It combines
high resolution digital processing with high performance audio and video components to bring you an
unrivalled home entertainment centre.
In addition to the built-in tuner, the AVR280 allows switching and volume control of seven analogue and
six digital sources, making it an ideal companion for both home cinema and two-channel stereo systems.
Since many of these source components are also capable of outputting high quality video signals,
the AVR280 includes broadcast quality video switching for composite, S-video, component, RGB- and
HDMI-video signals. There are inputs and outputs for both tape and VCR, as well as a digital output.
DVD-Audio or SACD can be connected via the multi-channel input. Control of the AVR280 is either by
front panel control buttons, IR remote control or an RS232 port (which also can be used to upload future
software enhancements).
As well as providing the audio and video being used in the main listening area, the AVR280 allows
the same, or a different, source to be routed to a second area (called ‘Zone 2’), such as the kitchen,
bedroom, lounge, etc. Zone 2 can have full remote control over the source selection and volume in that
area.
The customised installation of the AVR280 in a listening room is an important process which requires
care at every stage. For this reason, the installation information is very comprehensive and should be
followed carefully.
Using this handbook
Thank you for purchasing the Arcam AVR280 Surround Sound Receiver.
This handbook has been designed to give you all the information you need to install, connect, set up
and use the Arcam AVR280 Surround Sound Receiver. The remote control handset supplied with the
equipment is also described.
It may be that the AVR280 has been installed and set up as part of your Hi-Fi installation by a qualified
Arcam dealer. In this case, you may wish to skip the sections of this handbook dealing with installation
and setting up the unit and move directly to the section detailing the operation of your unit.

AVR280
Before making connections
Before connecting your equipment it is important to think about the following points, as these will affect
your choice of connections and subsequent use of the system.
Audio
English
Wherever possible, connect both analogue and digital outputs of digital sources. This enables use of
a digital input for the main zone with the corresponding analogue input used for recording onto an
analogue tape deck or VCR, or for the Zone 2 output.
Video
The AVR280 allows for conversion between different video formats. This means that the AVR280 can
convert between composite, S-video and component, if required.
For example, if you are watching a composite input from a VCR, you may view it from the S-video or
Component/RGB video outputs of the AVR280. This allows you to use a single (typically high-quality
Component/RGB) connection between the AVR280 and your display device.
However, neither the record loops nor Zone 2 work from the video converter. This means that to record
a S-video or composite signal, a S­‑video or composite signal (respectively) must be supplied; to
view video in Zone 2, a composite signal is required.
The video quality hierarchy is as follows:
<
<
<
Component/RGB – highest
S-video – middle
Composite – lowest
If all the video inputs are connected simultaneously from one device, e.g., a DVD player, the
AVR280 will select automatically the best format available.
Digital video (HDMI)
The AVR280 is fitted with two HDMI inputs and one HDMI output, allowing switching of HDMI
signals. In most cases, HDMI provides the highest quality video connection between your source
and your display. The AVR280 does not perform conversion between analogue audio/video and
HDMI.
HDMI signals cannot be routed to Zone 2. If you are using an HDMI connection and you wish to
have the same audio and video in Zone 2, then you will need additionally to provide analogue
audio and video connections (as described above).
Zone 2
A line-level signal from the stereo analogue audio together with the composite video inputs
are available for Zone 2. The analogue inputs from source components are required because
the AVR280 provides no analogue-to-digital, DSP processing or digital-to-analogue conversion;
the composite video connections are required since the AVR280 does not perform video format
conversion for Zone 2.
HDMI (High Definition
Multimedia Interface)
supports both video
and audio on a single
digital connection for
use with DVD players,
digital TV, set-top
boxes, etc. HDMI was
developed to combine
the technologies of
High-bandwidth Digital
Content Protection
(HDCP) and the Digital
Visual Interface (DVI)
in one specification,
with the addition of
transmission of digital
audio information; HDCP
is used to protect digital
content transmitted to
DVI-compliant displays.
For these reasons, we recommend that source devices that have a digital connection are also connected
to the analogue inputs. High quality YUV/RGB and S-video sources should also have their composite
outputs connected to the AVR280 for use in Zone 2.
Using the remote control
The remote control requires four ‘AAA’ batteries to operate. To insert the batteries into
the remote control, please follow the instructions in the side panel diagram:
Notes on inserting the remote control batteries
<
<
<
Incorrect use of batteries can result in hazards such as leakage and bursting.
Do not mix old and new batteries together.
Do not use different kinds of battery together—although they may look similar,
different batteries may have different voltages.
<
Ensure that the plus (+) and minus (—) ends of each battery match the
directions in the diagram on the right.
<
Remove batteries from equipment that is not going to be used for a month or
more.
<
When disposing of used batteries, please comply with government (or other)
regulations that apply in your country or area.
Reliable use
Please keep in mind the following when using the remote control:
<
Ensure that there are no obstacles between the remote control and the remote
sensor on the AVR280. The remote has a range of about 7 metres. (If the remote
sensor is obscured, the remote control input jack on the rear panel is available.
Please contact your dealer for further information.)
<
Remote operation may become unreliable if strong sunlight or fluorescent light is
shining on the remote sensor of the AVR280.
<
Replace the batteries when you notice a reduction in the operating range of the
remote control.
1. Open the battery
compartment by pressing
the button on the back of the
handset.
2. Insert four AAA batteries into
the battery compartment:
two with ‘+’ facing the top of
the handset, and two with ‘+’
facing the end cap, as in the
diagram.
3. Lower the end cap onto the
plastic locating plate in the
handset. This acts as a hinge,
and you can now push the
end cap firmly into its locked
position with a click.

The AVR280 rear panel
Positioning the unit
<
<
<
<
Place the receiver on a level, firm surface.
Avoid placing the unit in direct sunlight or near sources of heat or damp.
Do not place the unit on top of a power amplifier or other source of heat.
Ensure adequate ventilation. Do not place the unit in an enclosed space such as a bookcase
or closed cabinet unless there is good provision for ventilation. The receiver is designed to run
warm during normal operation.
<
Make sure the IR receiver in the centre of the front panel display is unobstructed, otherwise
this will impair the use of the remote control. If line-of-sight is impractical, an infrared remote
repeater can be used with the rear panel IR connector.
<
Do not place your record deck on top of this unit or any other unit which is mains supplied.
Record decks are very sensitive to the noise generated by mains power supplies which will be
heard as ‘hum’ if the record deck is too close.
IMPORTANT: Do not place any other component or item on top of the AVR280 as this may obstruct
the ventilation holes, causing the AVR280 to run hot. (The unit placed on top of the AVR280 would
become hot, too.)
Notes on installing the AVR280
The inputs are named to make it easier to reference when connecting source components to the AVR280
(e.g., a DVD or VCR), but all inputs have the same circuitry. This means that there is no reason why you
should not connect a different device from that labelled to any of the inputs. For example, if you had two
DVD players and the AV input was not being used, then the second DVD player could be connected to
the AV input.
Cables
We recommend the use of high quality screened analogue, digital and video cables, since inferior
quality cables will degrade the overall quality of your system. Use only cables that are designed for the
particular application as other cables will have different impedance characteristics that will degrade
the performance of your system (for example, do not use cabling intended for audio use to carry video
signals). All cables should be kept as short as is practically possible.
Video and digital connections must be made with cables that are designed for this purpose, i.e., coaxial
cable with a 75Ω impedance. If substandard cables are used you may suffer from poor picture quality
such as ghost images and/or grainy picture quality (snow).
Speaker cables should be kept short to ensure efficient power transmission and avoid audible distortion.
It is good practice when connecting your equipment to ensure that the mains power supply cabling is
kept as far away as possible from your audio and video cables, as this will provide the best sound and
picture quality. Failure to do so may result in unwanted noise in the audio and video signals.

Connect the left and right outputs of your source equipment to the left and right inputs.
Connection of record decks:
The AVR280 is not fitted with a phono pre-amplifier. If you wish to connect a record deck
to the AVR280, then you will need an external pre-amplifier. Please contact your dealer for
further information and recommendations on the best option for your system.

8 RIGHT, 9 LEFT, bk RIGHT SURROUND, bl LEFT SURROUND,
bo CENTRE, bp SUB.
Connect the audio outputs of your DVD-Audio or SACD player to these input sockets.
bm RS BACK, and bn LS BACK.
These are available for formats requiring eight channels. Currently no formats are available
requiring these connections, which are provided for future compatibility.
The multi-channel input is intended for use with sources that decode the surround channels
internally, such as DVD-A or SACD players.
The AVR280 switches these analogue inputs directly to the analogue outputs via its own volume
control circuit. This direct path maintains the best possible sound quality for DVD-A and SACD
sources; it has the side-effect that there is no bass-management for DVD-A or SACD players. In this
case, the bass-management functionality of the player itself should be used.

Connect the digital ouputs of your available source equipment to these inputs.
If required, each of these six digital inputs can be allocated to a different audio input from that
indicated by the input label, through the ‘Digital Settings’ page of the Set-up menu. This means that,
for example, if you wish to use an optical connection for your DVD player, the optical connection for
the SAT, AUX, or TAPE can be used and the audio from that digital input assigned to the DVD button.
Outputs
bt ck Digital OUT.
Two digital output connections are available: optical and coaxial. The two connections carry the same
information at all times and both may be used simultaneously. Connect the digital outputs to your
digital recording devices such as a CD-R, digital VCR or MiniDisc player.

When a digital source is selected, the digital output will send an exact copy of the incoming digital
signal. For example, for a 5.1 digital source, the digital output will also be in 5.1 format.
When an analogue source is selected, the digital output will be muted. These outputs are also muted
if a source is selected where the only connection for that source is HDMI. The digital audio from the
HDMI link (if any) is not routed to these outputs.

AVR280
Video connections
The AVR280 allows for conversion between different video
formats. This means that the AVR280 can convert between
composite, S-video and component, if required. For example, if
you are watching a composite input from a VCR, you may view
it from the S-video or Component/RGB video outputs of the
AVR280. This allows you to use a single (typically high-quality
Component/RGB) connection between the AVR280 and your
display device.
The record loops do not work from the video converter.
This means that to record a S-video or composite signal,
a S­‑video or composite signal (respectively) must be
supplied.
The following video conversions are possible:
To:
Composite
S-video
Component/
RGB
Composite
Yes

Note that conversion between RGB and Component video
(or vice-versa) is not supported by the AVR280.
Composite/S‑video video connections
�� �� ��
dm dn MONITOR OUT.
Two video output connectors are provided, one for S­‑Video and one for composite video. The outputs
carry the same information at all times (and both may be used simultaneously, if required).
Connect one of these outputs to the video input of your display device.
�����
�����
���
���
���
dq VCR IN, ds AUX IN, dt AV, ek SAT, el DVD.
Connect the composite video outputs of your source equipment to these inputs. The choice of
connection to use (S‑video or composite) depends on where the signal is to be routed to: if the
signal is to be used in Zone 2, then a composite connection is required; if the signal is to be used
for recording (routed to a VCR, for example), then the connection type must match the connection
to the recording device (i.e., if the recording device requires a S‑video signal, then a S‑video
connection from the source equipment must be used).
If both connections are made, the signal from the S‑video input will be used for the main zone if no
Component/RGB signal is supplied.

Connect one of the S‑video or composite video outputs to the video input of your VCR or AUX. The
connection used must match the video type of the source you wish to record (as described above).
For example: if you wish to record a S‑video signal from your satellite receiver on your VCR, the
connection to the VCR must also use S‑video.

High quality (Component) video connections
These inputs are suitable for connection to component (YUV/YCrCb) or RGB outputs. These
signals are usually available from a DVD player, set-top box or games console and offer the
best possible picture quality.
��
Note that the high-quality component video connections operate independently of the
composite/S-video connections.
Generally, the component video standard is used in North America/NTSC regions, while RGB
is used in Europe.

Important notes about HQ-video inputs and outputs
< In the ‘Video Settings’ set-up menu, each of these three high-quality component video
inputs can be allocated individually to any of the other inputs, e.g., the input labelled
‘DVD’ does not have to be used for DVD, but can be used for something else. See page
14 for further details.
< You cannot mix component and RGB sources. Selection of component or RGB can be
made in the Set-up menu ‘General Settings’ page (see page 10).
< The high-quality component video inputs have sufficient bandwidth for line-doubled
NTSC (525/60) or PAL (625/50) video (‘progressive scan’) and also US HDTV video
signals. However, when used with such signals the OSD is not overlaid on the picture
but is output at standard interlaced NTSC or PAL (525 or 625 line) rate on a solid
background.
When you connect
your devices to these
connectors, take care to
follow the letter/colour
coding for each input.
No damage will occur if
connected incorrectly,
but unusually coloured
or unstable pictures will
result.
< When using the HQ-video inputs, the composite and S-video outputs will be muted. This
is because the processing for the on-screen display would create invalid video signals on
these outputs.
SCART RGB 4-wire connection
(SCART refers to the multipole A/V connector used commonly on European A/V equipment.)
Some video projectors and most European TV sets require the use of a 4-wire RGB connection, where
the ‘sync’ signal is separate from RGB. In this case, you need to use the composite video MONITOR
OUT dn for the sync information. A cable is available from your dealer to make this 4-wire RGB
connection (refer to the table of SCART connections at the back of the manual). Note that use of this
feature requires (in addition to the RGB connections) a composite video connection between the source
and the AVR280, in order to supply the additional synchronisation signal.
Note that most SCART TV inputs will require the SCART RGB status line to be controlled before the RGB
signal will be displayed. The RGB trigger output will control this signal when connected to the SCART
socket using a cable of the type given on page 32. These cables are available from your dealer.
The AVR280 does not support either 5-wire RGB HV or 3-wire RGB sync-on-green connections.
AVR280
HDMI
An HDMI connection between a source and your display device offers the best possible picture quality.
This connection type is, however, the most limiting in terms of routing, advised cable length and
conversion.
���
�������
���
��������
English
The AVR280 provides two HDMI inputs; these are labelled ‘DVD’ and ‘SAT’ in anticipation of the most
common use for these connectors, but they may be used for any HDMI source. These inputs may be
configured to be associated with any of the other sources, so that selecting that source (‘AUX’, for
example), selects one of the HDMI inputs instead of the usual input associated with that source.
It is important to realise that analogue video sources cannot be routed by the AVR280 to the HDMI
output, nor can either of the HDMI inputs be converted to analogue video (of any sort). The AVR280 acts
simply as a switching device, selecting one of the inputs and routing it to the output.
Keeping the above in mind, it will be necessary (as with the high-quality analogue video connections),
to provide a composite video feed, in addition to the HDMI connection, if the video is to be routed to
Zone 2.
Connecting loudspeakers
The red and black terminals on the back of the AVR280 are used to make the connections to the
loudspeakers. The speakers should be connected to the loudspeaker terminals, refering to the
labels on the rear-panel.
When connecting the speaker terminals of the amplifier with the terminals on the speakers
make sure that like polarities are matched (i.e., match ‘+’ with ‘+’ (usually red) and ‘–’ with ‘–’
(usually black)). Mismatching of polarities will result in a weak central sound, unclear orientation
of the instruments and the sense of direction of the stereo being impaired.
There are two options for connecting the speaker cable to the amplifier:
Using bare wire ended leads:
1. Strip back the insulation on the wire to reveal about 2cm of conductor (the metal inside
the cable).
The speaker connectors
on the rear-panel are
labelled as follows:
FL - Front Left
FR - Front Right
CEN - Centre
RS - Right Surround
LS - Left Surround
RSB - Right Surround Back
LSB - Left Surround Back
2. If the conductor is stranded, twist the strands together tightly to avoid loose strands making
contact with the adjacent terminals or the back panel.
3. Loosen the terminal by turning it anti-clockwise
4. Insert the twisted wire through the hole in the terminal.
5. Tighten by turning clockwise.
When making connections with stranded bare ended wires, take great care that no individual strands of
wire come into contact with the adjacent terminals or with the back panel. If this should happen, it will
cause a short circuit on the output of the amplifier and could damage the amplifier.
Using spade terminals:
1. Loosen the terminal by turning it anti-clockwise
2. Insert the spade connector under the terminal.
3. Tighten by turning clockwise.
AVR280
Zone 2 connections
The AVR280 allows independent routing and control of analogue audio and composite
video to a second room such as a kitchen, bedroom or lounge. This second room is known
as ‘Zone 2’.
����
�
For Zone 2, the AVR280 outputs a line-level audio signal taken from the stereo analogue
audio, and a composite video signal taken from the composite video input (for a given
source). The analogue inputs are required because there is no analogue-to-digital, DSP
processing or digital-to-analogue conversion available for Zone 2 signals. As the AVR280
does not convert video formats for Zone 2, a composite video signal must also be
connected from the source.
For these reasons, we recommend that source devices that have a digital connection are
also connected via the analogue inputs. High quality YUV/RGB and S-video sources should
also have their composite video outputs connected to the AVR280 for use in Zone 2.
NOTE: As a composite input is required for Zone 2, it may not be
possible to run your DVD player in progressive scan mode and to use
Zone 2 at the same time, unless your DVD player can output both
progressive scan and composite signals simutaneously.

Connecting the AM and FM antennas
FM antenna
An FM antenna is required to receive VHF radio signals.
Although a FM ribbon antenna is supplied as an accessory to the AVR280, for optimal FM radio
reception a roof- or loft-mounted aerial is advised as this will give superior reception. (It is
recommended that any roof-top antenna is fitted by an experienced contractor as a contractor
will be able to align your antenna to the nearest FM transmitter.)
In some areas cable radio may be available or, in an apartment building, a distributed antenna
system may be installed. In either of these cases you should have sockets in your home marked
FM or VHF (do not use those marked TV), which should be connected to the FM in socket fr of
the AVR280.
Connecting the plug
to the FM ribbon cable:
1) loosen the two screws
on the plug;
2) insert the spade
connectors of the ribbon
cable under the screws;
3) re-tighten the screws
onto the connectors.
If you wish to use the supplied FM ribbon cable, mount this as high up as possible on a wall with
the ‘T’-elements positioned horizontally. Try each usable wall of the room to see which gives best
reception and use tacks or adhesive tape to secure the aerial in a T shape (note that no tacks
should come into contact with the internal wire of the aerial). When assembled (see box, right), the plug
on the ribbon cable should be connected to the FM in socket fr of the AVR280.
AM antenna
��
��
���
An AM antenna is required to receive AM/medium wave radio signals.
An AM loop antenna is supplied as an accessory with the AVR280. This should be attached to the AM
antenna inputs fq with one end connected to AM and the other to Ground (it does not matter which way
round this antenna is fitted). Rotate the antenna to discover which position gives the best reception.
In areas of weak reception, or when the AVR280 is in use inside a steel framed building (such as an
apartment building), you can use a wire between 3 and 5 metres long to strengthen reception. Mount
this high up outside the building (if possible) and connect one end of this wire to the AM antenna input
in addition to the loop aerial supplied (do not disconnect the AM loop antenna).
AM step size
The AM tuning ‘step size’ needs to be set according to your location. This is done using the switch on the
rear panel fs: set it to 10kHz if you are in North America or 9kHz anywhere else. Note that this should
be set correctly even if you do not intend to use AM reception as it also alters some FM tuner settings for
use in North America.

Configuring the AVR280
The AVR280 ‘Set-up Menu’ has six ‘Basic’ and five ‘Advanced’ menu screens that take you through
the configuration process. The ‘Basic’ menus enable you to match your AVR280 to your speakers; the
‘Advanced’ menus allow you to optimise the operation of your system. Screen shots of these menus are
shown in shaded boxes on the following pages.
The best way to set up the AVR280 is using the on-screen display (OSD). To view the OSD for the initial
set up, use the composite video output to connect to your TV. This is because the high quality video
output has several display modes and may be incompatible with your high quality display device in its
default configuration. Note that no on-screen display is available over the HDMI connection.
Set-up mode
To enter the Set-up menus press and hold the Menu button on the remote control or on the front panel,
for at least two seconds. The ‘Set-up Menu Index’ is displayed on your display device.
Set-up Menu Index
The Set-up menu index page is the first page that is displayed when the Set-up menu is
entered. This page allows you access to the six ‘Basic’ and five ‘Advanced’ menus.
Navigating the Set-up menu
… by using the remote control
The Set-up menu can be navigated by using the cursor (arrow) keys on the remote
control. This is by far the easiest method.
1. To enter the Set-up menu, press and hold the Menu button (which is located
immediately under the navigation buttons) for at least two seconds, until the
Index page appears. (Pressing the menu button for just a short time will take
you to ‘Main Menu Screen 1’. If this happens, the Main Menu can be closed by pressing menu for
a second time.)
2. When the menu heading is highlighted, using the D and E keys will navigate between menu
pages. Using this method to navigate between pages the first time the unit is being configured
will help to ensure that no pages are missed out.
3. Use the
B and C keys to navigate up and down the menu lines.
4. To change the setting for a particular menu item, highlight the item then use the
cycle through the options for that item.
D E keys to
5. Once you have set all the menu items on a page to have values that are appropriate for your
system, move the menu highlight to the top of the screen (the menu heading) and press E to
move to the next menu page.
6. At any time, press the Menu button to return to the main Set-up menu index screen.
7. To save the changes you have made, return to the Set-up menu index page and highlight the
‘Save Set-up’ item at the bottom of the screen. Press the OK button to save the settings. Press
OK again to exit the Set-up menu.
In addition to the above method of moving from page to page using the D E keys, each menu page
can be accessed directly from the Set-up menu index page. This is achieved by using the cursor keys to
move the menu highlight to the desired page on the Index page, then pressing OK.
… by using the buttons on the front panel of the AVR280
The AVR280 front panel controls can be used to configure the options. Follow the instructions given for
using the remote control, in this case using the effect/6 button for ‘down’, the mode/5 button for ‘up’
and the volume control for left and right.

The ‘Basic’ Set-up Menus
1 – General Settings:
Max Volume: This limits the maximum volume setting the system can be turned
up to. This is a useful feature to prevent accidental overdriving of low powerhandling speakers, for example.
English
Max On Volume: Limits the maximum volume the system operates at when it is
first switched on. The system comes on at the ‘Max On Volume’ if the last used
(possibly very loud) volume exceeds this value.
Delay units: Controls whether the delay settings for the speakers in surround
modes are specified in Imperial or Metric measurements from the listening
position, or in terms of time. Either enter the time delay to each channel if
calculating the delay in milliseconds, or select between Imperial or Metric
measurements and allow the AVR280 to calculate the time delay automatically.
Imperial is measured in feet and Metric is measured more precisely in 0.1m
(10cm) increments (1 foot is approximately 0.3 metres).
Note that changing the units resets all distances/times to zero. It is therefore
important to choose the units (Time, Imperial or Metric) before set up.
OSD Mode: Controls how the on-screen display is viewed.
<
<
Mixed: the OSD will appear on top of the existing video picture
Full Page: the OSD is displayed in white on a full screen black background.
On video signals that have a sync rate of greater than the normal interlaced rate (i.e.,
progressive scan, frame-scaled video, HDTV) the OSD will automatically go into Full Page mode
(black background) so that the control menu can be accessed. Any pop-up displays (such as the
volume bar, source selection information, etc) will be switched off.
Note that no on-screen display is available over the HDMI connection.
Video Status: The video status control is intended for use with SCART connections, but may find
use for other purposes. It is possible to use a SCART connection between the AVR280 and your
television even though the AVR280 does not have a SCART socket; a pin-out for a SCART lead
suitable for this purpose is given on page 32. We suggest the ‘SQART’ cables manufactured by
QED (www.qed.co.uk); please ask your dealer for details.
This setting controls the two video triggers fl fm on the rear panel and is used to inform the
AVR280 which type of video connection is present between it and your TV, in order that the
AVR280 can set the control lines correctly for SCART connections. Note that if you do not wish to
use the video triggers or a SCART connection, then it does not matter which value this item has.
This item has four settings: Composite, S-video, RGB and Scrn Ctrl.
Composite: This mode is used to
indicate to your TV that composite
video is being sent. It uses the trigger
labelled 1/RGB fl (which should be
connected to the RGB SCART input on
your TV), as shown. Select this option
if you are using the composite video
output of the AVR280.
The 2/S-video trigger is not active in
this mode.
S-Video: This mode is used to
indicate to your TV that S-video is
being sent. It uses the trigger labelled
2/S-video fm, as shown. Select this
option if you are using the S‑video
output of the AVR280.
Note that, if this option is selected,
the connection labelled ‘S-video
SCART’ (or similar) must be used on
the TV, as not all SCART connectors
are wired for S-video.
The 1/RGB trigger is not active in this
mode.
RGB: This mode is used to indicate to
your TV that RGB video is being sent.
It uses the trigger labelled 1/RGB, as
shown. Select this option if you are
using the RGB output of the AVR280.
If this option is selected, the
connection labelled ‘RGB SCART’ (or
similar) must be used on the TV, as
not all SCART connectors are wired
for RGB.
The 2/S-video trigger is not active in
this mode.

HQ Video: Choose between RGB or YUV; if you have a YUV display, set this item to YUV, otherwise
set it to RGB. Note that this setting has no effect on the HDMI output.
This setting controls the routing of the HQ-video within the AVR280, either as 3-wire YUV or 4wire RGB signals (with the synchronisation signal on composite for RGB). In addition, it controls
the operation of the S-video/composite-to-HQ video converter.
When set to YUV, incoming composite and S-video signals are converted to YUV; in RGB mode,
the iincoming signals are converted to RGB, with the synchronisation signal on the composite
output.

The Custom setting allows you to choose any combination of speakers to suit your system. Note that
the centre and rear speakers cannot be set to ‘large’ if the front speakers are set to ‘small’.
5.1 Rears defines how the speakers in a full ‘7.1’ installation handle 5.1 decoded sources.
< Surr L/R redirects 5.1 surround signal to the surround left and right speakers. No signal will be
directed to the surround back left or right speakers.
< Surr Back L/R redirects 5.1 surround signal to the surround back left and right speakers. No
signal will be directed to the surround left or right speakers.
< Both redirects the 5.1 surround signal to both pairs of speakers with the signal to each set
reduced by 3dB.
A note on speaker sizes:
A Large speaker is one that is capable of handling a full range signal (i.e., 20Hz–20kHz).
A Small speaker is one that is not capable of reproducing a deep bass signal (i.e., below 100Hz),
for example a satellite speaker.
None indicates that there is no speaker connected to that channel.
3 – Subwoofer Settings
If no subwoofer was selected in the previous speaker menus then some of the items on
this page will not be adjustable.
Cross-over Freq.: This setting defines the frequency at which bass redirection begins.
Frequencies below this level are redirected from ‘small’ speakers to the Fronts or to
the subwoofer; frequencies above this level are not redirected. The value for this
setting depends on your speakers, environment and taste, and is best determined by
experimentation.
The adjustment can be made in increments of 10Hz between 40Hz and 130Hz.
Stereo Mode: Select between Large, Large+Sub or Sat+Sub.
If you have configured your system to have a subwoofer, then you have the flexibility to
choose how bass information is distributed between the front left/right speakers and the
subwoofer when listening to stereo sources. Choose the option which gives you the most
solid even sounding bass (for best results test with a set-up disc or live program material).
<
Large: Pure stereo information – all audio is sent to the front left and right speakers. Use this
setting if you have large front speakers.
Note that this option will override the setting configured on the ‘Speaker Sizes’ menu page.
<
Large+Sub: Pure stereo is fed to left and right and extracted bass is sent to the subwoofer. In
this case the low frequency information is, effectively, duplicated.
<
Sat+Sub: Use this setting if you have ‘Small’ satellite left and right speakers. Full bass
management is used in analogue stereo so that analogue sources are fed to the DSP where the
bass is filtered off left and right and redirected to the subwoofer.
Note that the above three Stereo Mode settings pass the audio through the DSP, which may degrade
the sound quality slightly. This can be avoided for the ‘Large’ setting by pressing the Direct button to
bypass the DSP processing.
DTS LFE Gain: DTS soundtracks typically have the LFE track recorded 10dB lower than the main audio
tracks. It is, therefore, necessary to compensate for this by raising the LFE output level by 10dB, and
setting the DTS LFE gain to ‘Normal’ activates this compensation. Some DTS soundtracks have been
recorded with the LFE signal at the same levels as the main audio, however, and therefore require no
gain compensation. For these disks set the DTS LFE gain to -10dB.
<
<
AVR280
14
Normal: This increases the LFE signal by 10dB and is the recommended setting for the AVR280.
-10dB: This allows the LFE to pass directly to the output with no gain adjustment.
Unfortunately, there is no rule for determining which discs are recorded using which method. As a
general guide, however, it is only early DTS music discs that require the -10dB setting.
Sub Stereo: This setting allows the volume level of the subwoofer to be adjusted for when the
subwoofer is being used with 2-channel (stereo) sources. The subwoofer level for stereo music often
needs to be set at a lower level than that for cinema use; use this trim setting, with a stereo source, to
reduce the subwoofer output in stereo playback to an acceptable level. The level required depends on
various factors such as speakers, the types and styles of music to be played and personal taste.
DVD-A Sub Level: This setting allows compensation for subwoofer level gain from external decoders or
sources (such as DVD-A players).
<
Normal: No gain compensation. This allows the DVD-A sub level to pass directly to the output
with no gain adjustment.
<
+10dB: This increases the DVD-A (multi-channel input) sub level by 10dB
English
When decoding digital inputs, the AVR280 follows the convention for products of this type and sets the
subwoofer level 10dB higher than that of the other channels. Source products such as DVD-audio players
do not follow this pattern, however, setting the subwoofer level to be the same as the other channels.
This means that switching from material that has been decoded by the AVR280 to that decoded
externally may mean that the subwoofer sounds very quiet. This setting provides for the removal of that
difference by allowing the subwoofer level of the DVD-A (multi-channel) input to be raised by 10dB.
If you are using the AVR280 in combination with the multi-channel analogue outputs of an Arcam DVD‑A
player, then this item should be set to ‘+10dB’.
4 – Speaker Delay Settings
�����
����
The relative positioning of speakers within a room may mean that sound from some
speakers arrives at the listener later
than sound from others. By altering the
delay settings for the different speakers,
���������
������
this difference in arrival time can be
�����
reduced or eliminated.
�����
�������
�����
��������

�������
������
�������
�����
��������
�����
The speaker distance control can be
used to set automatically the appropriate time delays
required for all the speakers in your system. To use this,
measure from the usual listening position to the front
of each individual speaker in the system and enter this
value in the appropriate place. The measurements can
be entered either in feet or metres, as selected from the
‘General Settings’ menu page.
An alternative to using the speaker distance control is to
enter the delays manually in milliseconds.

channels to the primary listening position.
No measurement can be entered for a speaker that is
not selected in the previous ‘Speaker Sizes’ menu.
NOTE: Only enter these delay settings once you have specified which delay units (i.e., Time, Imperial
or Metric) you will be using. The delay settings will be lost if the units are changed.
If the delay units are set to Time, then enter the delay in milliseconds for each channel.

5 – Level settings
The relative sensitivity of different speakers can lead to some speakers sounding
disproportionately loud or quiet, relative to others in the system. The level settings of
your AVR280 can help to address this inbalance.
It is important to calibrate the speakers correctly to achieve an accurately centred sound
stage. If possible, we recommend you use a sound pressure level meter (SPL meter)
to perform this part of the set-up as it is difficult to judge the levels accurately by ear
alone.
Test Tone Cycle
<
Manual is best for setting up with a SPL meter as the test tone will not change
to the next speaker until instructed by you. Pink noise is emitted by the
highlighted speaker; when you wish to measure a different speaker, move the
highlight to the new speaker.
<
Auto is best for setting up by ear. In this state, the test tone changes automatically between
speakers after a two second burst of sound.
On first installation, watch the OSD display as you cycle through the available speakers with the test
tone. Check that the speaker generating the sound corresponds to that indicated on the OSD. If there is
a discrepancy then check and correct the system cabling before proceeding further.
To calibrate the speakers with a SPL meter, place the meter at ear level with the microphone pointing
towards the ceiling, when seated in the usual listening position. (You will need to set the meter to ‘C’‚
setting with a ‘slow’‚ response and to read 75dB SPL at the centre of the scale.) If you do not have a SPL
meter, simply set the front left speaker to 0dB on the menu and then match all the other speakers to
this level.
Each speaker can be fine-tuned by 1dB increments to ±10dB. The output from each speaker needs to be
adjusted to the 75dB SPL sound level. No adjustments can be made for a speaker that is not selected in
the previous ‘Speaker Sizes’ menu.
Note that inserting headphones into the front panel of the AVR280 will cause all test-tones to be muted
(including the headphone output).
NOTE: If you are using a 6.1 speaker configuration (a single surround back speaker), we recommend
connecting the surround back speaker to the surround back left channel of the AVR280.
In this case, the level of the connected surround back channel should be increased by 3dB (i.e., the
SPL meter should show a response of 78dB for this channel).
6 – EX Settings
Surr. EX: This can either be set to Auto or Manual and is applicable only when playing
‘Surround EX’-encoded material.
< Auto DD EX: The AVR280 will switch automatically to ‘Surround EX’ decoding
when suitably encoded material is detected (this can be temporarily overridden
by pressing the MODE button on the remote control).
< Auto PLIIx: The AVR280 will switch automatically to ‘Pro Logic IIx Movie’
decoding when suitably encoded material is detected (this can be temporarily
overridden by pressing the MODE button on the remote control).
< Manual: The AVR280 will not select Surround EX automatically. It can however
be selected manually by pressing the MODE button.
Use Channels 6+7 for
Choose one from:
< Dolby Surr EX: ‘Dolby Surround EX’ provides two additional rear channels from 5.1 channel
EX-encoded material. This is intended to give better effects steering. In this mode, amplifier
channels 6 and 7 are used to drive the EX speakers.
< Zone 2: In this mode, amplifier channels 6 and 7 are used to provide speaker level output for
use in Zone 2.
< BiAmp L+R: The amplifier channel 6 and 7 are used to provide a second amplified output of the
left and right channels. This allows you to bi-amplify your front speakers, which should give an
improvement in the sound quality of these channels.
If you would like to do this, please refer to page 26 for further information.
NOTE: Changing this setting will require you to change the configuration of the cables connected your
speakers.

The ‘Advanced’ Set-up Menus
ADV 1 – Speaker Eq.
English
This allows fine adjustment of bass and treble in 1dB steps (up to ±6dB) for each of the
speakers in the system. Use these adjustments sparingly to compensate for speaker
response problems caused by positioning, adjacent surface textures, or mixed brands of
loudspeakers.
Work with one speaker on at a time and, as an example, use the bass control to reduce
boom problems for speakers placed in corners, and the treble control for speakers
placed near reflective surfaces. We recommend trying to obtain a good speaker
response by speaker placement first, then apply speaker equalisation last.
The tone control nominal corner frequencies are at 100Hz and 8kHz, shelf type.
Auto Stereo Tone Bypass: Set this item to yes if, when a stereo input signal is
detected (analogue or digital), the tone adjustments set on this page are to be bypassed. (Note that this does not switch the AVR280 into ‘Direct’ mode, it simply sets the
tone controls to zero.)
ADV 2 – Video Settings
This menu allows advanced adjustment of the video settings for your AVR280.
Zone 1 OSD: Selects whether the main zone OSD is on or off.
<
When set to On‚ all user adjustments that are made during the general use of
the AVR280 are displayed on the screen. This includes the adjustment of the
volume control, the inputs selected and the set-up menus.
<
When set to Off‚ there will be no display of the general user adjustments – only
the set-up menus and the main menus are displayed.
It is recommended you keep the OSD turned On‚ since if you cannot see the front panel
of the AVR280 you will have no idea if any adjustments you have made to the processor
are correct or to your liking.
Video Inputs: Composite and S-video inputs for DVD, Sat, AV, VCR and AUX have their
audio and video assigned to track each other by default. The five ‘Video Input’ lines for Tape, CD, FM,
AM and DVD-A allow assignment of a video source to these normally audio-only sources. If desired, it is
possible to allocate the same video source to more than one audio input. This facility allows you to listen
to an audio source and view a separate video source at the same time – for example, you can listen to
radio while watching TV for a sports simulcast.
HQ Video DVD, AV and SAT: Allocate the high quality component or RGB video inputs to any source
buttons. For example, to assign the Component/RGB video from the ‘HQ Video DVD’ input to the DVD
button, set the ‘HQ Video DVD’ item in this menu to ‘DVD’.
If HQ-video is set to RGB (as described on page 13) and an HQ-video input is assigned to a button,
the AVR280 assumes that RGB signals are present for that input if a composite signal is found on the
corresponding composite input. If this assignment is made but no RGB signals are supplied, the
display will be blank for the assigned source.
ADV 3 – Digital Settings
Coaxial inputs and Optical inputs. Each of the digital inputs can be assigned to any
of the seven stereo source buttons (CD, Tape, DVD, Sat, AV, VCR and AUX), or can be
assigned No button.
This menu page lists the physical inputs, as per the back panel, on the left hand side of
the screen, with the buttons used to select the inputs listed on the right hand side.
Each digital input can be allocated only to one source button. For example, if you choose
the ‘Coaxial DVD input’ to be assigned to the DVD button, then the choices for the other
digital inputs are: CD, Tape, Sat, AV, VCR, AUX and No button. If you wish to reallocate the DVD input to a different button, ‘Coaxial DVD input’ must be assigned to a
different button (or No button) before you can re-assign the DVD input.
AVR280

ADV 4 – Zone 2 Settings
Zone2 vol: Sets the volume for Zone 2.
Max Vol 20–83: Limits the maximum volume setting for Zone 2. This is a useful
feature to prevent accidental overdriving of low power-handling speakers, for example.
Fix Vol: This selects between fixed and variable audio output to Zone 2. If No is
selected, the output level can be controlled from Zone 2 or the main system. If you wish
to fix the volume level, first set the Zone 2 volume to the desired level, then select Yes.
Max On Vol: Limits the maximum volume Zone 2 operates at when it is first switched
on. Zone 2 comes on at this volume if the last used volume exceeds this value.
Stand-by: This allows zone 1 (the main zone) to be put into stand-by, either locally
only or by Zone 2 as well.
< Local Only: Only the main zone will be switched into stand-by from the main
zone.
< All Off: Both the main zone and Zone 2 will be switched into stand-by from the main zone.
Access: This acts as a ‘parental control’ device to disable or enable access to sources for Zone 2.
Press the unwanted source button on the remote control handset or front panel to disable it for Zone 2.
Press again to enable the source.
Enabled sources are listed on the ‘Access:’ line of the menu page.
ADV 5 – Analogue Settings
Input trims: Allows the adjustment of the input sensitivity of the analogue inputs (in
Volts rms) so that each one achieves the optimum dynamic range and sounds similar in
loudness to the others.
Available level settings are: Low 0.5V, Medium 1V, Reference 2V, High 4V. The
reference level of 2V should be appropriate for most inputs.
If a source is very quiet compared with the other sources you can increase its loudness
by selecting the Medium 1V or Low 0.5V settings.
ADV 6 – HDMI Settings
The AVR280 provides two HDMI inputs; these are labelled ‘DVD’ and ‘SAT’ in anticipation
of the most common use for these connectors, but they may be used for any HDMI
source. These inputs may be configured to be associated with any of the other sources,
so that selecting that source (‘AUX’, for example), selects one of the HDMI inputs
instead of the usual input associated with that source.
NOTE: If the DVD button is assigned to an HDMI input, you will also be able to view the
HDMI signal from the DVD player if the MCH (DVD-A multi-channel) button is selected.
Saving Settings and Exit Set-up
You can either save the settings now or exit without saving the changes.
Save Set-up
1. Press Menu to go to the ‘Set-up Menu Index’ at the ‘Save Set-up’ point.
2. Press OK to save.
3. Press OK to select ‘Exit Set-up’ and exit system configuration.
Exit without saving
If you choose to ‘Exit Set-up’ without first saving the changes, then the new settings will be lost.
1. Press Menu to go to the ‘Set-up Menu Index’ at the ‘Save Set-up’ point.
2. Press
E to select ‘Exit Set-up’.
3. Press OK when ‘Exit Set-up’ is selected to exit system configuration.

For information display we recommend you use the OSD on your TV/screen whenever possible. However,
all key information is also duplicated one line at a time on the front panel display of the AVR280.
Switching on/off
Press the power button in. After approximately two seconds, the power LED will turn green and the
current input and volume level will be shown; after a further 10 seconds, the AVR280 is ready for use.
Please wait until the unit has finished initialising before attempting to operate the AVR280. It is
recommended that if the unit is switched off, you should wait at least 10 seconds before switching the
unit back on.
Stand-by
The AVR280 has a stand-by mode which can be entered by pressing the green stand-by button on the
remote control. When in stand-by mode the display is blank and the power LED glows red. If you do not
wish to put Zone 2 into stand-by at the same time as the main zone, press and hold the stand-by button
on the remote control for about 3 seconds. After this time, the front-panel of the AVR280 will display the
text ‘Main Off’, before going into stand-by; the LED for Zone 2 will be illuminated to show that Zone 2 is
still operating.
When not being used, the AVR280 may be left in stand-by mode, as power consumption is low. If you
are not using your AVR280 for several days, however, we recommend you switch the unit off completely
using the front panel power button.
To switch on from stand-by, press one of the source buttons on the front panel or on the remote control,
or use the stand-by button on the remote control.
Volume control
To adjust the volume level of the loudspeakers, pre-amp outputs and headphones use the volume
control knob. The volume level is shown on the display. Note that different sources may require different
settings of the volume control to achieve the same perceived volume level.
It is important to realise that the value indicated for the volume level is not an accurate indication of
the power delivered to your loudspeakers. The AVR280 may deliver its full output power long before the
volume control reaches its maximum position, particularly when listening to heavily recorded music.
In comparison, some movie sountracks can appear to be very quiet, as many directors like to keep the
maximum levels in reserve for special effect sequences.
The volume can be controlled over a range of 100dB in 1dB steps.
Muting the volume
Pressing the mute button will mute the output of the AVR280 to the speakers and from the ‘pre-amp
out’ connectors (the output to the record loops remains unaffected). ‘MUTE’ will be shown on the display
while in this state.
Press mute for a second time (or adjust the volume) to exit the mute state.
Front panel display
In normal operation, the display shows the current volume setting; smaller illuminated areas indicate the
audio input type (digital or analogue) and the digital stream type (if applicable). If the processing mode
changes (for example, from Dolby Pro Logic decoding to Dolby Digital 5.1), then this will be displayed ‘in
large letters’ for about 2 seconds.
Changing the display brightness (the
display
button)
It is possible to select the illumination level of the front panel display. Press DISPLAY on the front panel
or DIS on the remote to cycle through the three illumination levels (Off/Dim/Bright).
AVR280
21
Input selection
To select a particular source, press the corresponding button on the front panel or on the remote control.
There are eight inputs available: DVD, Sat, AV, AUX, VCR, Tape, CD and MCH (DVD-A multi-channel). In
addition, AM and FM radio reception can be selected from the built-in tuner. Any picture signal associated
with the selected input is switched to the monitor output.
On selecting a source, the AVR280 will attempt to use the digital input in preference to an analogue
input, assuming a digital signal is detected for the source. If you want to override the digital input and
select the analogue input instead, however, this can be achieved by pressing and holding the button for
the selected source for at least two seconds.
The processing mode and ‘Stereo Direct’ functions are remembered and recalled for each input. The
digital input and high quality video input associated with each source may be configured in the device
menus.
The DVD-A input is intended for direct analogue pass-through of DVD Audio or SACD surround sources.
Apart from volume control and level trim, no processing is performed on this input.
Tape operation
The TAPE button selects the audio from a cassette deck connected to the TAPE IN phono sockets of the
AVR280.
Pressing the tape button will select audio from the tape input; the tape LED will illuminate, together
with the LED of the previously selected input. Illuminating the tape and source LEDs indicates that the
tape loop is active and indicates the source that will be recorded.
Example:
If you want to record from the CD input:
<
<
Select the CD input;
Press the tape button – you can now listen to the sound returned from the recording device. In
the case of a three-head cassette deck, this will be the audio as recorded onto the tape.
Note that selecting a different source from CD will cause the recording to change to this new source.
VCR/AUX Operation
The AVR280 has VCR and AUX record loops for audio and video (Composite and S-video only). These
carry the audio and video (if any) from the currently-selected source. The VCR output is muted if VCR is
the selected source; the AUX output is muted if AUX is the selected source.
Example:
If you want to record the SAT input:
<
<
<
Select the SAT input.
Press the button labeled ‘record’ (or similar) on your VCR/AUX to begin recording.
Note that, if you select a different source from SAT, the recording changes to this new source.
Stereo Direct
To listen to a pure analogue stereo input, press the Direct button. The Direct mode bypasses
automatically all processing and any surround functions. In Direct mode, digital processing is shut down
to improve the sound quality by reducing the digital noise within the AVR280 to an absolute minimum.
The LED above the DIRECT button on the front panel will illuminate to indicate this mode.
Important: When ‘stereo direct’ mode is enabled, bass management is disabled. For this reason,
‘stereo direct’ mode is not recommended in systems comprising small ‘satelite’ speakers, as the fullfrequency information that would be directed to these units may cause damage to the speaker.
Zone 2
Pressing the Zone 2 button allows both the volume and the source being viewed in Zone 2 to be changed
from the main zone. While in this ‘Zone 2’ mode, the LED above the Zone 2 button is illuminated.
When first pressed, the text ZONE2 SRC is displayed on the front panel (where ‘SRC’ indicates the source
being viewed in Zone 2). Pressing the source buttons on the front panel while in this state changes the
source routed to Zone 2; moving the volume knob adjusts the Zone 2 volume.
To exit this state, press Zone 2 a second time.
Headphones
To use headphones with the AVR280, plug the headphones into the socket on the left hand side of the
front panel.
When headphones are plugged into the headphones socket the main output is muted.

Mode
When a selected digital input carries a Dolby Digital or DTS signal,
the AVR280 detects it automatically and processes the signal
accordingly.
For an analogue input or when no Dolby Digital or DTS signal is
detected, pressing the MODE button cycles through the available
surround sound modes; for Dolby Digital or DTS signals, the mode button cycles through the processing
modes available for these types of signal. All of the available modes are detailed later in this handbook,
starting on page 26.
The selected mode is displayed in the main section of the display for three seconds, before reverting to
show the current volume. The surround mode continues to be shown on the display.
Treble/Bass
These allow you to alter temporarily the bass and treble controls for all currently active speakers. In the
case of Stereo, this would only apply to the front left and right speakers. In Effects, Pro Logic IIx Music,
Dolby Digital and DTS modes (for example), this would apply to all present speakers.
You can adjust the bass and treble by up to ±6dB. These adjustments are in addition to those made in
‘Speaker Eq’ in the Set-up Menu. However, the maximum overall tone control range for each speaker
using this screen plus the settings in ‘Speaker Eq’ is still ±6dB (not ±12dB).
To select the speaker to be adjusted, press the Treble/Bass button repeatedly until the desired speaker is
shown on the front-panel display. Then use the volume control knob to adjust the setting up or down.
Note that bass and treble alterations are not available in Stereo mode when Auto Stereo Tone BypasS
is set to Yes, or in Stereo Direct mode.
Remote control buttons
In addition to the buttons detailed above, the following remote control buttons are also relevant.
SUB
This button on the remote allows adjustment of the Subwoofer volume. Press SUB, then adjust using the
D E buttons on the navigation pad.
INFO
This button has the same effect as the RDS button on the front panel. See below for details of its
operation.
SYN
Delays may be introduced into the video signal by external video processing equipment which causes
a mismatch between the audio and video timing. You will notice this by speech sound being out of
synchronisation with the lip movements in the video.
To compensate for this you can adjust the lip sync audio delay. Press SYN and use the
buttons to change the delay.
D E navigation
See page 22 for a full explanation of this feature.
TRM
This allows temporary adjustment of the speaker levels. Press TRM to access the OSD ‘Speaker Trims’
menu, using the navigation buttons to adjust the levels required. Press again to exit the trim function.

Using the tuner
The AVR280’s radio tuner can be controlled from the upper row of front panel buttons (see diagram,
below) or from the remote control handset. Note that the tuner behaviour can be seen only via the frontpanel display, as there is no on-screen display for the tuner.
Tuning to a station
Pressing the PRESET/TUNE button (or TM on the remote) toggles between the two tuning modes of the
unit – ‘Tune’ or ‘Preset’. The selected mode is shown briefly on the display. When in frequency display
mode, the frequency will be followed by a ‘T’ in tune mode, and ‘P’ in preset mode.

Tune mode
In Tune mode:
<
Press the 3 and 4 buttons on the front panel (or P– or P+ on the remote control handset) for
longer than two seconds to engage automatic tuning. The tuner searches for a radio station
signal of sufficient strength and stops. To skip to the next station, press one of the buttons
again. Automatic tuning is available for both the FM and AM bands.
<
Tapping the 3 and 4 buttons engages manual tuning. This can be used for tuning to a specific
frequency. It is also useful if you are trying to select a station that is too weak for the autosearch mode.
Regardless of the mode used to tune your AVR280, when it is accurately tuned to a station ‘TUNED’
lights up in the display.
Preset mode
When one or more presets have been defined, ‘Preset’ mode can be used. In Preset mode, use the 3
and 4 buttons on the front panel (or P– or P+ on the remote control handset) to cycle up and down the
preset stations.
See below for instructions on storing and deleting presets.
Storing a preset
To store a preset, tune to the radio station you wish to store. Press the STORE button (or DYN on the
remote control): the station frequency is shown on the display, followed by a preset number. Select the
preset number you wish to assign to the station using the 3 and 4 buttons on the front panel (or P– or
P+ on the remote control handset), then press the STORE button again.
Once the preset is stored, the display reverts to show the station name (if RDS information is
transmitted) or its frequency.
To quit the memory function without storing a preset, leave the tuner controls untouched for five
seconds. It is also possible to overwrite a stored station by saving another in its place. There are thirty
presets available for FM use and ten for AM use.
Deleting a preset
Press the STORE button, then select the preset number you want to delete using the 3 and 4 buttons
(or P– or P+ on the remote control handset), followed by the FM MUTE/MONO button (1/Status on the
remote control).
The display briefly shows ‘DELETE’ and ‘– –’ is shown in place of the preset number. You can reactivate a
deleted preset number by storing a station in the normal way.
RDS: Radio Data System
The Arcam AVR280 supports RDS Programme Service and RDS Radio Text on FM broadcasts.
When a station carrying RDS information is selected ‘RDS’ lights up in the display and shortly afterwards
the station’s RDS name (e.g. ‘BBC R3’) is shown.
Press the RDS INFO button to view any RDS text information (if a station is not transmitting text
information, the display briefly indicates ‘NO TEXT’ and reverts to show the station name).
Press RDS INFO again to display the station’s frequency.
Pressing RDS INFO a third time returns you to a display of the station name.
If the RDS INFO button is pressed while tuned to a non RDS station, the display shows ‘NO NAME’ for
three seconds before reverting to the default display.
AVR280

FM Mute/Mono
The AVR280’s tuner has an auto-muting circuit that, when engaged, mutes any signal that is of
insufficient strength for listening. To engage this circuit press the FM MUTE/MONO button on the front
panel: ‘FM MUTE’ is shown in the display. If a signal is muted you will hear no sound through the
loudspeakers.
English
Should you wish to listen to a station that is ‘auto muted’ press the FM MUTE/MONO button again to
disengage the muting circuit. The tuner now switches to monoaural reception, cancelling much of the
background hiss. ‘FM MUTE’ is no longer displayed and you are able to continue listening.
Listening to the tuner in Zone 2
The tuner can be selected, as other inputs, for routing to Zone 2. Note, though, that it is not possible to
listen to different stations in the main zone and Zone 2 simultaneously. This is because the AVR280 is
fitted with just a single tuner module.
Using the Main Menu
Three ‘Main Menu’ screens allow day-to-day changes to be made to the way the AVR280 operates.
Examples include adjusting the tone control for a particular input, or selection of ‘direct’ mode.
The three Main Menu screens are available on your display device. The selected line of each screen is
also displayed on the front panel of the AVR280. Each of the following sections has a picture showing the
screen that is displayed as you move through the menus.
Using the remote control to enter the Main Menu
Briefly press the MENU button to enter ‘Main Menu Screen 1’. Use the navigation B and C buttons
to go up and down the menu respectively. The D and E buttons are used to alter the selection on the
highlighted line, or to change to the next screen if the menu heading is highlighted.
Using the front panel to enter the Main Menu
Press the MENU button to enter the main menu. To cycle through the items on a menu, use the
EFFECT /6 button to go down and MODE/5 button to go up one line for each press. Use the volume
control knob for the D and E functions in order to cycle through the available choices, or to change the
menu page if the menu heading is highlighted.
Main Menu Screen 1
Vol: Shows the present volume being used for the main zone and can be adjusted
from here.
Audio Input: This shows the current audio input source selected. The current
audio input can be changed when this line is highlighted using the source select
buttons on the front panel or the remote. Note that changing the audio input
also changes the video input to the same setting.
Video Input: This shows the current video input source selected. The current
video input can be changed when this line is highlighted using the source select
buttons on the front panel or the remote.
Changing the video input does not change the audio input, so you can watch a
different input from the one you are listening to.
If the audio and video are set to different inputs, they will be reset to be the
same input when the audio input is next changed.
NOTE: the composite/S-video inputs and the high-quality video inputs are
independent of each other. If you are watching a video source by using the one of the
high-quality video inputs, it is not possible to change the video input independently of
the audio.
Video Type: This setting is applicable only to TVs being fed via a SCART lead where the trigger
outputs fl and fm are connected via suitable SCART header. It shows the video aspect ratio
currently selected for the display, which can be set manually to 4:3 or 16:9, depending on which
format you are feeding into your TV. See page 12 for further details on using these triggers.
Stereo Direct:
<
<
Off: the AVR280 functions in its normal way.
On: the AVR280 uses the analogue input signal for the source, bypassing the digital circuitry.
In this mode, the AVR280 functions like an analogue amplifier: it also shuts down all the unused
digital circuitry for optimum stereo performance. Note that no digital output is available in this
case.
Bass and Treble: These allow you to alter temporarily the bass and treble controls for all currently
active speakers. In the case of Stereo, this would only apply to the front left and right speakers.
In Effects, Pro Logic IIx Music, Dolby Digital and DTS modes (for example), this would apply to
all present speakers.
You can adjust the bass and treble by up to ±6dB. These adjustments are in addition to those
made in ‘Speaker Eq’ in the Set-up Menu. However, the maximum overall tone control range for
each speaker using this screen plus the settings in ‘Speaker Eq’ is still ±6dB (not ±12dB).
Note that bass and treble alterations are not available in Stereo mode when Auto Stereo Tone
Bypass is set to Yes, or in Stereo Direct mode.
Balance: To alter temporarily the sound balance between the front left and right speakers. You can
alter the sound stage to either the left or right by up to 10dB. Note that it is not possible to shift
the audio signal completely over to one channel.
AVR280

Main Menu Screen 2
Compression: Allows selection of three different compression ratios (off, medium
and high), where the higher compression is intended for ‘late night’ listening.
The compression effect increases the volume of the quiet passages and
decreases the volume of the louder passages. Compression can be disabled by
setting this item to Off.
Compression is only available on Dolby Digital recordings and on some DTS
recordings.
Lip Sync: Allows the introduction and adjustment of a time delay between the
audio and video signals to compensate for the sound and picture not being
synchronised. This may be required when extra video processing is used in the
system, for line doubling or progressive scan video, or for when a DVD has been
poorly mastered or a broadcast shows noticeable delay between the video and
audio.
The lip sync function works on all sources, unless Stereo Direct is selected. Lip sync is also
directly available on the SYN button on the remote control.
The range of lip sync delay is 0 to 220 milliseconds.The lip sync adjustment can only correct for
delayed video: if the audio is delayed, set lip sync to its minimum.
Pro Logic IIx Music Mode: This allows the adjustment of the sound field for Dolby Pro Logic II/IIx
Music decoding of two-channel sources.
< Dimension: allows the user gradually to adjust the soundfield

either towards the front or towards the rear. If a recording is
too spacious or strong from the surrounds, it can be adjusted
‘forward’ to get a better balance. Likewise, if a stereo recording
is somewhat too ‘narrow’ sounding, it can be adjusted toward the
rear to get a more enveloping, immersive result. We recommend
‘Dimension’ is set to 3 for normal use.
< Centre Width: With Pro Logic decoding,
dominant centre signals come only from the
centre speaker. If no centre speaker is present,
the decoder splits the centre signal equally to
the left and right speakers to create a ‘phantom’
centre image. The Centre Width control allows
variable adjustment of the centre image so it may
be heard only from the centre speaker; only from
the left/right speakers as a phantom image; or
from all three front speakers to varying degrees.
We recommend ‘Centre Width’ is set to 3 for
normal use.

Surround modes
Introduction
English
Your AVR280 processor provides all the key decoding and processing modes for analogue and digital
signals.
Modes for Digital sources
Digital recordings are usually encoded to include information about their format type. The AVR280
detects automatically the relevant format in a digital signal, such as Dolby Digital or DTS, and switches
in the appropriate decoding.
Modes For Analogue sources
Analogue recordings do not contain information about their encoding formats, so the desired decoding
mode – such as Dolby Pro Logic – needs to be selected manually.
Mode Memory
The AVR280 has a comprehensive memory that allows it to store different settings for each source
button. The text below applies to all inputs except ‘DVD-A’.
Dolby Digital or DTS audio data (sometimes collectively referred to as ‘bitstream’ sources) can be output
in three mix modes, selected using the MODE button:
<
<
<
Surround (e.g., five main channels plus a subwoofer for a 5.1 source)
Stereo Downmix
Mono Downmix
The AVR280 will remember which mix mode was last used with a bitstream source. See ‘Multi-channel
Source Modes’ for more information.
Two-channel audio, regardless of whether it is analogue or digital also can be output in three mix modes,
selected using the MODE button:
<
<
<
Surround (e.g., Dolby Pro Logic IIx Movie, Neo:6 Music, etc.)
Stereo (with effects applied for analogue or digital PCM)
Mono
The AVR280 will remember which mix mode was last used with a two-channel source and, if ‘Surround’,
which particular surround mode. See ‘Two Channel Source Modes’ for more information. If an effect
mode has been applied whilst in Stereo, this will also be remembered.
There is a link between the mix modes for multi-channel bitstream (e.g., 5.1) and two-channel bitstream
(2.0 or 2.1) sources. If a 5.1 source is played in Surround mix mode, the AVR280 will remember this
for all bitstream sources (e.g., DTS-ES Matrix, Dolby Digital 3.0 etc.) and use the maximum number of
speakers the signal is encoded for. As a result, when a 2.0 or 2.1 bitstream is played the Surround mix
mode is recalled and the AVR280 enters Dolby Pro Logic IIx Movie mode to try to recreate the surround
environment from what may be a Pro Logic encoded source. If you would rather listen to a 2.0 or 2.1
bitstream in ordinary stereo (with or without a subwoofer), press MODE to cycle through to the Stereo
mix mode (e.g., Dolby Digital 2/0.0 on the display). However, if the source becomes multi-channel
bitstream (e.g., 5.1) again, the AVR280 will recall Stereo mix mode and therefore output a Stereo
Downmix of the multi-channel signal. Full surround output can be re-achieved by pressing MODE to cycle
through to the surround mode encoded on the disc.
Digital multi-channel sources
Digital multi-channel source material is normally provided as ‘5.1 audio’. The ‘5.1 channels’ comprise of:
left, centre and right front speakers, two surround speakers and a low frequency effects (LFE) channel.
Since the LFE channel is not a full range channel, it is referred to as ‘.1’.
Surround systems decode and reproduce the 5.1 channels directly. Dolby Digital EX and DTS-ES
enhanced decoding systems create one extra rear channel from information buried in the two surround
signals of the 5.1 source. These EX and ES enhanced systems are sometimes referred to as ‘6.1’
systems. This extra surround back channel is normally reproduced through two separate loudspeakers,
creating a ‘7.1 system’.
5.1 Playback on 7.1 speaker systems
When listening to 5.1 channel digital recordings, such as Dolby Digital and DTS on a 7.1 channel speaker
system you will have two speakers producing no sound. These two surround back speakers can be
assigned the same signal as the surround speakers in the ‘Speaker Sizes’ page of the Set-up Menu.
When both the surround and surround back speakers are selected the volume from both will be reduced
by 3 dB to keep the sound levels in balance.

Two-channel source modes
The following decoding and surround modes are available:
<
<
<
<
Mono
Stereo
Pro Logic II/IIx Movie
<
<
<
Pro Logic Emulation
Neo:6 Cinema
Neo:6 Music
Pro Logic II/IIx Music
These modes are available with two-channel analogue and two-channel PCM digital sources (although a
Dolby Digital 2.0 source may only be decoded as Mono, Stereo or Pro Logic IIx Movie).
Mono: The AVR280 will combine the left and right audio channels from a stereo signal to produce a
mono signal. This can be of benefit when playing older audio recordings or VCR tapes, especially
mono LP records.
Analogue Stereo: In this mode the AVR280 works as a conventional high quality audio amplifier.
Note that if the subwoofer is enabled in stereo mode, then some processing of the signal will be
carried out. For ultimate sound quality with analogue sources, therefore, select the Stereo Direct
function.
Digital Stereo: Decodes two-channel digital signals such as PCM signals from sources such as CDs
and some DVDs.
Dolby Pro Logic II/IIx: Dolby Pro Logic II decoding is designed to produce a 5-channel output
from two channel source material. This is extended by Dolby Pro Logic IIx decoding, which is
designed to produce a 5- or 7-channel output from two-channel source material and a 7-channel
output from 5-channel material.
There are two different modes available in Pro Logic II/IIx: ‘Movie’ and ‘Music’ modes, which are
intended for use as their names suggest. Due to the different recording methods used for movies
and music, it is recommended that the correct decoding mode for your source material is used
to obtain the best results.
<
Movie Mode: This is intended for use with ‘cinematic’ material, which is mixed and monitored in
a calibrated multi-channel environment. Movie mode is a ‘fixed’ mode that is designed to give a
similar sound when listening using a home cinema system to that obtained in a cinema.
< Music Mode: Stereo music is not designed for surround processing, although good surround
effects can be obtained through careful production. As the optimum decoding method varies
according to the recording, Music mode allows user adjustment of the processing characteristics.
Information about adjusting the Music mode by using ‘Dimension’ and ‘Centre Width’ controls
can be found in the ‘Main Menu Screen 2’ section.
Dolby Pro Logic: Dolby Pro Logic decoding is a legacy mode that is designed to produce a fivechannel output from two-channel source material. It should be used only when the source
material is encoded as Dolby Pro Logic; otherwise, we recommend the use of Dolby Pro Logic
IIx. This is because Pro Logic processing on straight stereo sources can sound muffled and
compressed.
DTS NEO:6: DTS Neo:6 provides up to six full-band channels of decoding from stereo material.
The AVR280 will derive separate channels corresponding to the standard home theatre speaker
layout.
<
Cinema: A movie mode designed to reproduce a movie theatre environment. Neo:6 technology
allows various sound elements within a channel or channels to be steered separately, and in a
way which follows the original presentation naturally.
<
Music: A music mode designed to produce a lively, high-integrity surround-effect from most twochannel music sources from all available speakers. Neo:6 music mode expands stereo recordings
into the five- or six-channel layout without diminishing the subtlety and integrity of the original
stereo recording.
Multi-channel source modes
The following modes are available for multi-channel digital sources. Special modes like DTS-ES 6.1
Matrix and DTS-ES 6.1 Discrete are available only from the correct source material.

Dolby Digital 5.1: The most commonly used sound format for DVD video, and is also the standard
for US digital television. Dolby Digital 5.1 sources deliver surround sound with five discrete fullrange channels; left, centre, right, surround left, and surround right, plus a low frequency effects
(LFE) channel.
Dolby Digital Ex: This is an extension to Dolby Digital decoding that provides a 6-channel output
from a 5-channel input. The extra channel is the centre-surround channel (for which the two
surround back speakers are used), and is derived from the left and right surround channel
information. This decode mode should be used only when the source material is ‘Surround
EX’ encoded (which is normally indicated on the disc packaging and should be detected
automatically by the AVR280), but may be used at other times if desired.
Dolby Digital Pro Logic IIx: This is an extension to Dolby Digital decoding that provides a 7channel output from a 5-channel input. The extra channels are the surround back channels, that
are derived from the left and right surround channel information.
DTS 5.1: Less common than the Dolby Digital format, but generally recognised within the audio
industry as being of superior sound quality. DTS 5.1 delivers surround sound with five full range
channels plus an LFE channel.
AVR280
28
DTS-ES 6.1 Matrix: This is a 6.1 channel format based on DTS 5.1. It has the sixth channel matrix
encoded into the surround left and surround right channels. The sixth channel is a surround
centre channel and is directed to the surround back left and surround back right speakers.
DTS-ES 6.1 Discrete: This is a true discrete 6.1 channel sound format (unlike DTS-ES 6.1 Matrix
where the sixth (surround centre) channel information is extracted from the two surround
channels). DTS-ES 6.1 Discrete mode operates only on sources with DTS-ES 6.1 Discrete audio
encoding, such as certain DVD discs.
A list of available software titles with DTS-ES 6.1 Matrix and DTS-ES 6.1 Discrete titles can be found at
www.dtsonline.com.
English
DSP Effects Modes
The AVR280 has a number of effects modes that can be used to enhance a stereo signal and to make
use of the surround loudspeakers. DSP effects modes are only available with stereo source signals.
Music: Music surround makes full use of the additional speakers placed at the centre, sides and rear
of the room. This effect uses ambiance extraction for the side and rear speakers and offers the
most subtle surround processing with no reverberation or reflections.
Party: The Party effect allows unprocessed stereo signals to be played over all speakers for
background music or for maximum acoustical output of the system.
Club: The Club effect generates reflections and short reverberation information to the front, side and
rear speakers. It simulates a small club venue, such as a Jazz Club.
Concert Hall: The Concert Hall effect generates the ambient information for the simulation of
a medium size hall. Reflections and medium length reverberation information are sent to all
channels.
Sports: Sports stadium effect is ideal for use when watching live sports events which would
normally be in stereo. The open ambience of a sports stadium is actively recreated around you,
except from the centre channel which is kept clear for commentary.
Church: The Church effect uses a reverberation algorithm which emphasises rich, smooth
reverberant decay in large spaces. As its name suggests, it works well for simulating a space
with long reverberation time relative to its size, such as a large church or cathedral.
Speaker positioning
The AVR280 allows you to connect up to seven speakers and
an active subwoofer in the main system. The output channels
correspond to speakers installed in the front left, centre, front
right, surround left, surround right, left surround back, right
surround back and an active subwoofer (see diagram).
All speakers, with the exception of the subwoofer, should be
arranged around your normal viewing/listening position (see
diagram). The subwoofer should be placed in accordance with
the instructions of the manufacturer; experiment with it in
various positions to obtain the best result.

Position your front left and right speakers to achieve a good
stereo image for normal musical reproduction. If they are
placed too close together there will be a lack of spaciousness;
if they are placed too far apart a stereo image will appear to
have a large ‘hole’ in the middle and will be presented in two halves. If there is no practical alternative
to placing the speakers widely apart, this effect can be overcome in music reproduction by using centre
sound extraction from the left and right speakers (see the description of ‘Dolby Pro Logic IIx Music Mode’
later in this handbook).
Centre
The centre speaker allows for a more realistic reproduction of dialogue and centre sounds. The centre
speaker should have a similar tonal balance to the front left and right speakers and be positioned at a
similar height.
Surround left and right
The surround left and right speakers reproduce the ambient sound and effects present in a multi-channel
home cinema system and (for home theatre use) should be installed approximately one metre higher
than the listener’s ears.
Surround back left and right
The surround back left and right speakers are used to add extra depth and better sound localisation and
should be installed approximately one metre higher than the listener’s ears. Place the two surround back
speakers such that there is an arc of approximately 150 degrees between each surround back speaker
and the centre speaker. The surround back speakers should face the front of the room as shown in the
diagram to provide the largest ‘sweet spot’.
Note: if you have a 6.1 speaker system, with a single surround back speaker, we recommend that you
connect this speaker to the surround back left channel of the AVR280.
Subwoofer
A subwoofer will greatly improve the bass performance of your system. This is useful for reproducing
special cinema effects, especially where a dedicated LFE (Low-Frequency Effects) channel is available, as
with many Dolby Digital or DTS encoded discs.

Bi-wiring and bi-amping loudspeakers
Bi-wiring improves the sound of your system as it divides the high and low frequency signal currents into
separate speaker cables. The performance of your system can be further enhanced over that achieved
with bi-wiring by extending the principle one stage further to include separate amplification for the low
and high frequency drive units in each loudspeaker enclosure. This is called ‘bi-amping’.
Before you start – important information!
�������������
1. Ensure that the volume control is set to minimum before starting these procedures.
2. Do not make any connections to your AVR280 while it is switched on or connected to the
mains supply.
��
�����
����������
3. After connecting the loudspeakers, but before switching on the AVR280, please check all
connections thoroughly, making sure bare wires or cables are not touching the AVR280 in
the wrong places (which could cause short circuits) and that you have connected positive
(+) to positive and negative (–) to negative.

Bi-wiring your loudspeakers
Bi-wiring avoids signal distortions arising from the high and low frequency currents interacting
with one another within a single cable, as occurs in conventionally wired systems.
You will need:
Speakers – with four input terminals each: the terminals will be marked HF (High Frequency
+ and –) and LF (Low Frequency + and –).
Loudspeaker cables – two pairs of cables per loudspeaker.
�
�
��
How to bi-wire loudspeakers
1. Remove the terminal links on the rear of your loudspeakers.
��
�
�
Note that If you do not remove the shorting links from the speaker terminals, the
speakers will still be single-wired!

AVR280 (only one speaker
is shown, for clarity)
2. Connect the cables as shown in the diagram, ensuring correct polarity at all times.
Bi-amping your system
Notes:
<
In order to bi-amplify your speakers, your speakers will need to be bi-wirable (have
positive and negative terminals for both high frequency (HF) and low frequency (LF)
information). If your speakers are bi-wirable, ensure that the links between the HF and LF
terminals are removed.
WARNING: This step is essential or damage to
your AVR280 may result which is not covered
under warranty.
<
If you wish to bi-amplify speakers using external
power amplifiers, you must use amplifiers with the
same gain as the AVR280 (31dB), otherwise the
bass and the treble will become unbalanced. Please
contact your dealer if you require more information
on bi-amping your speakers.

Bi-amping using the AVR280
If channels 6 and 7 of your system are not in use (i.e., you

Check that:
<
<
you have a digital connection from your DVD player.
sometimes Dolby Digital DVD discs contain material
at either the beginning or the end of the main movie
that is not in full 5.1 format, but in two-channel or Pro

Hum on an analogue input:
Check that:
< all cables are making a good connection. If necessary
withdraw the cable from the connector and plug it fully
in again. (Turn the power off before doing this.)
< the connections inside the source cable connector are
not broken or badly soldered.
< if the hum originates only when one particular source
component is connected, that an aerial, cable or dish
connection to this source is ground isolated. Contact
your installation contractor.
< try switching the ground lift switch on the back panel.
There is radio or television reception interference:
< check where the interference is coming from. Switch
off each source component in turn, then any other
equipment. Most electronic equipment does generate
low levels of interference.
< try re-arranging cabling from the nuisance source
away from other cabling
< ensure that the cabling used is high quality, specified

No Zone 2 audio when playing DTS film:
Most two-channel DVD players cannot output a stereo
decoded version of the DTS signal – the analogue outputs
are muted when playing back DTS films. If you want to
watch a DVD in both the Main zone and Zone 2, please use
the Dolby Digital sound track.
No centre image (vocal) in Zone 2 when using the
multi-channel input:
Most DVD/SACD players are unable to provide a two-channel
down-mix of source material at the same time as decoding
a multi-channel audio stream. Therefore, only the front
left and right channels from the multi-channel mix will be
available in Zone 2.
To overcome this, play the stereo mix from the DVD-audio
disc instead.
Strange aspect ratio of video in Zone 2:
Most DVD players can only decode video to one aspect ratio
at a time. For example, if you are using wide screen in the
main zone, then wide screen information will also be fed to
Zone 2.
To overcome this, either set the film to 4:3 for the main
zone when you want to use Zone 2 as well, or change the
Zone 2 display to a wide screen capable type.
Unable to adjust bass and treble controls:
Bass and treble is not available in ‘Direct’ mode. For
Analogue Stereo and Digital Stereo modes, check that the
‘Auto Stereo Tone Bypass’ line of ‘Speaker Eq’ in the Set-up
Menu is set to No.
Digital signal drops out when other electrical
appliances turn on (heating, fridge, freezer, etc.):
If a poor quality or incorrect type of cable has been used for
the digital inputs, they can pick up electrical noise. Change
the cable to a 75Ω low loss coaxial type.
Check the connections have not oxidised. Clean the
connectors with contact cleaner if they appear oxidised.

IR Remote Codes
The following information is supplied for owners of advanced programmable remote controls, such as the
Philips ‘Pronto’ and similar devices, where it is possible to program remote codes directly into the device.
The coding system for the AVR280 is based on the Philips RC-5 standard. The main system control uses
RC-5 system codes ‘16’, with the tuner section using system code ‘17’ (this is to provide compatability
with existing ARCAM tuners). So, for example, to program in a ‘Stand-by’ command, use the command
‘16-124’.
Zone 2 also uses RC-5 system code 16 as standard, as Zone 2 is normally operated in a separate room
using a standard (system code 16) remote control.
Main system control code, system code 16. Items shown in this style indicate the equivalent remote
control button of the supplied CR100 remote control.

Radio interference
The AVR280 is a digital audio device which have been designed to very high standards of
electromagnetic compatibility.
The unit can radiate RF (radio frequency) energy. In some cases this can cause interference with FM and
AM radio reception. If this is the case, keep the AVR280 player and its connecting cables as far from the
tuner and its aerials as possible. Connecting the AVR280 and the tuner to different mains sockets can
also help to reduce interference.
