AND FUNCTION

BI-AMPLIFIER CONNECTIONS

Four channels of this unit's power amplifiers are used to achieve bi-amplifier connections to the front speaker systems.

Before connecting the speaker systems, check that they support bi-amplifier connections.

What are "bi-amplifier connections"?

This is a technique for enhancing sound quality, and it involves connecting separate power amplifiers to the bass and mid-range/treble speakers.

By adopting this technique, interference in the mid-range and treble sound caused by the back electromotive force generated by the bass speaker unit can be minimized, improving the sound that can be delivered through the front speakers.

Notes:

•Balanced cables are used in the connection example shown. (Unbalanced cables can also be used for bi-amplifier connections.)

•If the front speaker systems are used in combination with the AV8003 in a bi-amplifier connection, sound will no longer be heard from the surround back channels.
