CONNECTING SPEAKER SYSTEMS
Connect the SPEAKERS terminals to your speakers with wire of
the proper gauge, cut as short as possible. If the connections are
faulty, no sound will be heard from the speakers. Make sure that the
polarity of the speaker wires is correct, that is, + and – markings are
observed. If these wires are reversed, the sound will be unnatural
and will lack bass. Do not let the bare speaker wires touch each other
or any other metal part as this could damage this unit and/or
speakers.
NOTE: Use speakers with the specified impedance shown on the
rear of this unit.
