Connecting speakers
To connect each of the speakers, unscrew the
corresponding terminals on the back of the AVR400,
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 AVR400.
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.

Bi-Amping the Front Left & Right speakers
Bi-amping is the use of two amplier 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 amplier
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 AVR400. Connect the tweeter or HF terminals to the SBL and
SBR terminals on the AVR400. 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-32.
Using external power ampliers
e internal power amplier of the AVR400 can
be supplemented or replaced with external power
amplication. Connect the PREAMP OUT sockets to your
power amplier inputs:
FL, FR, C
Connect these to the equivalent (Right, Le and Centre)
front channels of your power amplier.
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 amplier
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
amplier inputs.
All pre-amplier analogue outputs are buered, have
a low output impedance and are at line level. ey are
able to drive long cables or several inputs in parallel if
required.
Connecting subwoofers
e AVR400 also allows an active subwoofer to be connected to the SUB output.
See your subwoofer handbook for the
correct setting up and connection for
your particular subwoofer.
Speaker cables
e speakers should be connected to the amplier using
good-quality, high-purity, low impedance copper cables.
Cheap speaker cables should be avoided – they are a
false economy and can signicantly 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.
