Connecting Speakers
To connect each of the speakers, unscrew the corresponding
terminals on the back of the Receiver, 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 Receiver.
Ensure the unit is switched o whilst connecting speakers.
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 Receiver. Connect the tweeter or HF terminals to the SBL and SBR terminals on
the Receiver. Finally, navigate to the Setup Menu ‘Spkr Types’ and set the ‘Use Channels 6+7 for’ menu option to ‘BiAmp L+R’;
see page EN-32.

The Receiver also allows up to four active subwoofers to be connected to the or outputs. Refer to your
subwoofer handbook for the correct setting up and connection procedure for your particular subwoofer(s).
Using external power ampliers
The internal power amplifier of the Receiver can be
supplemented or replaced with external power amplification,
such as the Arcam PA720. Connect the sockets to
your power amplifier inputs:
