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 and 7.1 speaker setups.
