connected to the red (positiv e/+ ) terminal on the back
panel, and the b lack (negativ e/– ) terminal of the speaker
is connected to the black (nega tive/– ) terminal on the
back p anel.
I t is importan t that no stra y strands of wire fr om these
connections ar e allowed to to uch another cab le or the
product casin g. Failur e to ensure this ca n cause a short
circuit and da mage yo ur A VR750/450/380.
Do not over -tigh ten th e loudspea ker termi nals, or use a

Speaker cables
e speakers should be connected to the am plier using
good-quality , hig h-p urity , l ow impedance co pper cables.
Cheap speaker cables sho uld be avoided – they ar e a
false econom y and can signican tly degrade the sound
quality .
e cable runs to the speakers sho uld be as short as
practicable. Connections t o the speaker terminals
should alwa ys be nger tight, whether using bar e wires
or sp ade con nectors .

Bi-amping the Fr ont Left & Front Right speak ers
Bi-am ping is the use of two a mplier ch annels per speaker . B i-amp ing can
pro vide better sound quality tha n conv entional single wiring. I f you do not h ave
Surro und Back speakers (i.e. you ha ve a 5.1 surro und system, not a 7.1 s ystem)
then you can use the spar e Surroun d Back speaker outp uts to bi-am plify the
fron t le and right speakers, if yo ur speakers support bi-a mpin g. e spare
channels ca n alternativ ely be used to power ster eo speakers in another room
(Zone 2).
Speakers that su pport bi-am ping ha ve two sets of +/- terminals per speaker ,
usually linked together by m etal strips. ese metal strips MUST be re mov ed
when bi-am ping; fail ure to remo ve them will result in dam age to the am plier
that is no t covered unde r warranty .
T o bi-am p the front le a nd right speakers, remo ve the metal strips from
the speaker terminals. Connect the woofer or LF terminals to the FL a nd FR
terminals on the A VR750/450/380. Connect the tweeter or HF terminals to the
SBL and S BR terminals on the A VR750/450/380. Finally , navigate t o the Setup
Men u ‘ Spkr T ypes’ and set the ‘U s e Cha nnels 6+7 for ’ menu o ption to ‘ BiAmp
L+R ’; see page E-26.
