Speaker connections

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.
CAUTION
• If you will use 6 ohm speakers, be sure to set
this unit's speaker impedance setting to
6 ohms before using (see page 25). If you will
use 8 ohm speakers, use this unit's initial
setting for speaker impedance.
• Before connecting the speakers, make sure that this
unit is disconnected from the power source.
• 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
speaker still creates 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.
