Loudspeaker connections

To avoid damaging the speakers with a sudden high-level signal, be sure
to switch the power off before connecting the speakers. Check the
impedance of your speakers. Speakers with an impedance of between
4 and 8 ohms (each) are recommended.
The coloured speaker terminals are positive (+) and the black speaker
terminals are negative (-). Make sure correct polarity is maintained at
each speaker connector or the sound can become weak and "phasey"
with little bass.
Prepare the speaker cords for connection by stripping off approximately
10mm (3/8") or less (no more than 10mm, as this could cause a short-
circuit) of the outer insulation. Twist the wire tightly together so there are
no loose ends. Unscrew the speaker terminal knob, insert the speaker
cable, tighten the knob and secure the cable.
Note: All connections are made via loudspeaker cable, except if using an
active subwoofer which would be connected via a standard RCA phono
cable. Banana Plugs (4mm standard) connected to the speaker cable
are recommended for direct insertion into the speaker terminals.
Please refer to the 'Speaker Configuration' section of this manual for
more information on 5.1, 6.1 and 7.1 speaker setups.
