How to connect speakers

Connecting the speaker
Connect a speaker cable between the negative (–) terminal of the unit and the
negative (–) terminal of the speaker, and between the positive (+) terminal of the unit
and the positive (+) unit of the speaker.
Notice
When connecting the speaker cables, take notice of the following:
▪ Prepare speaker cables in a place away from the unit, to avoid accidentally dropping wire strands into
the unit's interior which could result in a short circuit or malfunction of the unit.
▪ Improper connecting of the speaker cables may cause a short circuit and also damage the unit or the
speakers.
– Twist the bare wires of the speaker cables firmly together.
– Do not let the bare wires of the speaker cable touch one another.
– Do not let the bare wires of the speaker cable come into contact with the unit's metal parts (rear panel
and screws).
