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).
