It is important that no stray strands of wire from these
connections are allowed to touch another cable or the back
panel. Failure to ensure this can cause a short circuit and
damage your Receiver.
Ensure the unit is switched off while 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
high-quality, copper cables. A heavy gauge (thick copper)
and as short as practical is ideal. The gauge should be heavier
(a lower number) for longer runs. Using speaker cables that
are too long and/or thin gauge can significantly degrade the
sound quality.
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).
HDMI
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

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.
