o 9.1-channel playback (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.

0 When making bi-amp connections, be sure to remove the short-circuiting plate or

wire between the speaker's woofer and tweeter terminals.

z The height speakers, ceiling speakers and Dolby Atmos Enabled speakers can

be connected to the HEIGHT1 speaker terminals. Set the speaker to be

connected from "Height" - "Layout" in the menu. (v p. 243)
