7.1-channel playback (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.
