Connecting Speakers
Connect the speaker wires carefully to the speaker terminals
on the rear panel so as not to mistake the left and the right
channels or reverse the speaker polarities (+ and —).
Use sufficiently thick wire (18 gauge for short lengths,
16~12 gauge for longer lengths). It is recommended to use
color-coded wire for easy polarity identification. Speaker
wires should be as short as possible, and the left and the
right channel wires should be the same length.
1. Remove about 3/4 inch (20 mm) of insulation from the
end of each wire and twist the strands of each end.
3/74 inch
2. After making sure of the correct channel and polarity,
loosen the SPEAKER SYSTEM terminal knob and insert
the conductor directly into the recess at the upper-left of
the terminal. Then tighten the terminal knob, and the end
of speaker wire is automatically wound around the
terminal.
CAUTION: Two speaker systems can be connected to this
unit. The minimum speaker impedance should be 4 Ohm
when only one speaker system is connected. When two
speaker systems are connected, care should be taken that
net impedance does not become less than 4 Ohm.
