SPEAKER SETUP

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 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.
