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

e speakers should be connected to the amplier using

good-quality, high-purity, low impedance copper cables.

Cheap speaker cables should be avoided – they are a

false economy and can signicantly degrade the sound

quality.

e cable runs to the speakers should be as short as

practicable. Connections to the speaker terminals

should always be nger tight, whether using bare wires

or spade connectors.

Bi-amping the Front Left & Front Right speakers

Bi-amping is the use of two amplier 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 le and right speakers, if your speakers support bi-amping. e 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. ese metal strips MUST be removed

when bi-amping; failure to remove them will result in damage to the amplier

that is not covered under warranty.

To bi-amp the front le 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

e internal power amplier of the AV950/

AVR750/450/380 can be supplemented or replaced with

external power amplication. Connect the PREAMP OUT

sockets to your power amplier inputs:

FL, FR, C

Connect these to the equivalent (Right, Le and Centre)

front channels of your power amplier.

SUB

Subwoofer output. Connect this to the input of your

active subwoofer, if present.

SR, SL

Surround Right and Surround Le outputs. Connect

these to the Surround Right and Le power amplier

inputs.

SBR, SBL

Surround Back Right and Surround Back Le outputs

(only used in 7.1 channel systems). Connect these to the

Surround Back Right and Surround Back Le power

amplier inputs.

All preamplier analogue outputs are buered, have

a low output impedance and are at line level. ey are

able to drive long cables or several inputs in parallel if

required.

e 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. e 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 nished initialising

before operating the AV950/AVR750/450/380. It is

recommended that if the unit is switched o, you should

wait at least 10 seconds before switching the unit back

on.

Standby

e 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 le 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

e AV950/AVR750/450/380 is ready for use aer about

four seconds.

BD 37

e display window shows the currently selected source

and the last selected information view setting (this

information line can be changed using the INFO button).

e current volume setting for Zone 1 (37.0dB in the

above example) is displayed on the front panel. e

volume setting for Zone 2 is displayed temporarily

whenever it is adjusted.

Selecting a source

To select a particular source, press the –INPUT or

INPUT+ buttons until that source is shown on the front

panel display, or (if available) press the corresponding

source button on the remote. e following sources are

available:

is market dependent and may

not be available on your AV950/

DISPLAY

e 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 Cong.’ 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.

e 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. e 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. e AV950/

AVR750/450/380 oen 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 eects 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). e

two-channel down-mix is required so that the centre
