Connecting speakers
To connect each of the speakers, unscrew the
corresponding terminals on the back of the
AVR750/450/380, insert the speaker wires through the
hole in each post and screw the terminals back up. Make
sure that the red (positive/
+
) terminal of the speaker is
connected to the red (positive/
+
) terminal on the back
panel, and the black (negative/
–
) terminal of the speaker
is connected to the black (negative/
–
) terminal on the
back panel.
It is important that no stray strands of wire from these
connections are allowed to touch another cable or the
product casing. Failure to ensure this can cause a short
circuit and damage your AVR750/450/380.
Do not over-tighten the loudspeaker terminals, or use a
wrench, pliers, etc., as this could damage the terminals
and this would not be covered under the product’s
warranty.
Speaker cables
The speakers should be connected to the amplifier using
good-quality, high-purity, low impedance copper cables.
Cheap speaker cables should be avoided – they are a
false economy and can significantly degrade the sound
quality.
The cable runs to the speakers should be as short as
practicable. Connections to the speaker terminals
should always be finger tight, whether using bare wires
or spade connectors.

Bi-amping the Front Left & Front Right speakers
Bi-amping is the use of two amplifier channels per speaker. Bi-amping can
provide better sound quality than conventional single wiring. If you do not have
Surround Back speakers (i.e. you have a 5.1 surround system, not a 7.1 system)
then you can use the spare Surround Back speaker outputs to bi-amplify the
front left and right speakers, if your speakers support bi-amping. The spare
channels can alternatively be used to power stereo speakers in another room
(Zone 2).
Speakers that support bi-amping have two sets of +/- terminals per speaker,
usually linked together by metal strips. These metal strips
MUST
be removed
when bi-amping; failure to remove them will result in damage to the amplifier
that is not covered under warranty.
To bi-amp the front left and right speakers, remove the metal strips from
the speaker terminals. Connect the woofer or LF terminals to the FL and FR
terminals on the AVR750/450/380. Connect the tweeter or HF terminals to the
SBL and SBR terminals on the AVR750/450/380. Finally, navigate to the Setup
Menu ‘Spkr Types’ and set the ‘Use Channels 6+7 for’ menu option to ‘BiAmp
L+R’; see page E-26.
Using external power amplifiers
The internal power amplifier of the AV950/
AVR750/450/380 can be supplemented or replaced with
external power amplification. Connect the
PREAMP OUT
sockets to your power amplifier inputs:
FL, FR, C
Connect these to the equivalent (Right, Left and Centre)
front channels of your power amplifier.
SUB
Subwoofer output. Connect this to the input of your
active subwoofer, if present.
SR, SL
Surround Right and Surround Left outputs. Connect
these to the Surround Right and Left power amplifier
inputs.
SBR, SBL
Surround Back Right and Surround Back Left outputs
(only used in 7.1 channel systems). Connect these to the
Surround Back Right and Surround Back Left power
amplifier inputs.
All preamplifier analogue outputs are buffered, have
a low output impedance and are at line level. They are
able to drive long cables or several inputs in parallel if
required.

The AV950/AVR750/450/380 also allows an active subwoofer to be connected to
the
SUB
output. Refer to your subwoofer handbook for the correct setting up and
connection procedure for your particular subwoofer.
Operating your AV950/
AVR750/450/380
For information display we recommend you use the
OSD (On-Screen Display) on your display device
whenever possible.
Switching on
Press the front panel power button in. The power
LED will glow green, the front display shows the word
‘
ARCAM
’. When initialisation is complete, the display
shows the volume setting and the name of the selected
input.
Please wait until the unit has finished initialising
before operating the AV950/AVR750/450/380. It is
recommended that if the unit is switched off, you should
wait at least 10 seconds before switching the unit back
on.
Standby
The AV950/AVR750/450/380 has a standby mode which
can be entered by pressing
STANDBY
on the remote
control. When in standby mode, the display is blank and
the
POWER
LED glows red.
If the unit is to be left unused for an extended period,
we recommend that you disconnect it from the mains
supply to save power.
To switch on from standby
Press the
STANDBY
button on the remote control or any
key on the front panel (other than the power button).
Front panel display
The AV950/AVR750/450/380 is ready for use after about
four seconds.

The display window shows the currently selected source
and the last selected information view setting (this
information line can be changed using the
INFO
button).
The current volume setting for Zone 1 (37.0dB in the
above example) is displayed on the front panel. The
volume setting for Zone 2 is displayed temporarily
whenever it is adjusted.

Selecting a source
To select a particular source, press the –

buttons until that source is shown on the front
panel display, or (if available) press the corresponding
source button on the remote. The following sources are

DISPLAY
The Audio Return Channel (ARC)
from an HDMI 1.4-compliant display.
Use this with an HDMI 1.4-compliant
television using internal TV tuners.
Most audio inputs have both analogue and digital
connections. You must specify the type of connection
used for each input using the ‘
Audio Source
’ option in
the ‘Input Config.’ menu, see page E-29. Note that an
incorrect setting will result in no sound — the default is
HDMI audio. If you are not using HDMI audio then this
setting must be changed.
The processing mode and Stereo Direct functions are
remembered and recalled for each individual input.
Stereo Direct
To listen to a pure analogue stereo input, press the
DIRECT
button. The Stereo Direct mode automatically
bypasses all processing and any surround functions. In
direct mode, digital processing is shut down to improve
the sound quality and reduces digital noise with the
AV950/AVR750/450/380 to an absolute minimum.
Note: when Stereo Direct mode is selected, no
digital output is available and no bass management
is performed, meaning that bass signals will not be
redirected to a subwoofer.
Volume control
It is important to realise that the level of the volume
indicator is not an accurate indication of the
power delivered to your loudspeakers. The AV950/
AVR750/450/380 often delivers its full output power
long before the volume control reaches its maximum
position, particularly when listening to heavily recorded
music. In comparison, some movie sound tracks
can appear very quiet, as many directors like to keep
maximum levels in reserve for special effects sequences.
Headphones
To use headphones with the AV950/AVR750/450/380,
plug the headphones into the
PHONES
socket in the
centre of the front panel.
When headphones are plugged into the front panel
PHONES
socket, the outputs for Zone 1 are muted and
the audio will be down-mixed to two channels (2.0). The
two-channel down-mix is required so that the centre
