How to Connect:
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 the + and –
markings are observed. If these wires are reversed, the sound will be unnatural and lack bass.
Caution
Do not let the bare speaker wires touch each other and do not let them touch any metal part of this unit. This could damage
this unit and/or speakers.
