SPEAKER SETUP
Be sure to connect the left channel (L), right channel (R),
“+” (red) and “–” (black) properly. If the connections are
faulty, no sound will be heard from the speakers, and if the
polarity of the speaker connections is incorrect, the sound
will be unnatural and lack bass.
• If you will use 6 ohm speakers, be sure to set
this unit’s speaker impedance setting to 6
ohms before using (see page 21).
• Before connecting the speakers, make sure that the
power of this unit is off.
• Do not let the bare speaker wires touch each other or
do not let them touch any metal part of this unit. This
could damage this unit and/or speakers.
• Use magnetically shielded speakers. If this type of
speakers still creates the interference with the monitor,
place the speakers away from the monitor.
A speaker cord is actually a pair of insulated cables
running side by side. One cable is colored or shaped
differently, perhaps with a stripe, groove or ridges.
Connect the striped (grooved, etc.) cable to the “+” (red)
terminals on this unit and your speaker. Connect the plain
cable to the “–” (black) terminals.
1
Remove approximately 10 mm of insulation
from the end of each speaker cable.
2
Twist the exposed wires of the cable together
to prevent short circuits.
3
Unscrew the knob.
4
Insert one bare wire into the hole in the side
of each terminal.
5
Tighten the knob to secure the wire.
■ Banana plug connections
(With the exception of U.K., Europe and Asia models)
First, tighten the knob and then insert the banana plug
connector into the end of the corresponding terminal.
