Connecting 7.1-channel speakers: Bi-amp connection of front speakers
This system plays back 7.1-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.
You can connect speakers for up to 9-channels for MAIN ZONE. When you connect speakers for 8 or more channels, the output speakers automatically switch according to the input signal and sound mode.

When making bi-amp connections, be sure to remove the short-circuiting plate or wire between the speaker’s woofer and tweeter terminals.
