Connecting 9.1-channel speakers: Bi-amp connection of front speakers
This system plays back 9.1-channels. You can use the bi-amp connection for front speakers. Bi-amp connection is a method to connect separate amplifiers to the tweeter terminal and woofer terminal of a speaker that supports bi-amplification. This connection enables back EMF (power returned without being output) from the woofer to flow into the tweeter without affecting the sound quality, producing a higher sound quality.
Up to 11.2-channels can be connected by using either UNBALANCED RCA connectors or BALANCED XLR connectors.
This example explains how to make a connection when using UNBALANCED RCA connectors.
