BI-AMPLIFIER CONNECTIONS

Four channels of this unit's power amplifi ers are used to achieve bi-amplifi er connections to the front speaker
systems.
Before connecting the speaker systems, check that they support bi-amplifi er connections.
What are "bi-amplifi er connections"?
This is a technique for enhancing sound quality, and it involves connecting separate power amplifi ers 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-amplifi er
connections.)
• If the front speaker systems are used in combination with the AV8003 in a bi-amplifi er connection, sound will no
longer be heard from the surround back channels.
