Simple version Front A/B connection The second set of front speakers can be connected to the SURR. BACK/AMP ASSIGN terminals. In this case, set "Set up "Amp Assign"" (vpage 51) to "Front B". 2.1-channel connection ENGLISH Connect Bi-Amp connection A bi-amp connection is to connect separate amplifiers to the tweeter terminals and woofer terminals of speakers compatible with the bi-amp function. This prevents the back electromotive force (returned force without output) of the woofer sent to the tweeter, which affects the sound quality of the tweeter, and you can enjoy playback with higher-quality sound. In this case, set "Set up "Amp Assign"" (vpage 51) to "Bi-Amp". Basic version Advanced version FL SW FR SW FL(B) FL(A) FR(A) FR(B) nnFor connecting two subwoofers Two subwoofers can be connected to this unit.

Front speakers can be used separately, depending on the speaker's specifications or playback source such as front speakers (A) for multichannel playback and front speakers (B) for 2-channel playback (vpage 79 "Front Speaker Setup"). When making a bi-amp connection, the same signal is output from the front speaker terminal and the SURR.BACK/AMP ASSIGN terminal. For surround playback of a multichannel source, if you connect the center speaker, surround speakers and subwoofers, 5.1-channel playback is available. NOTE • Use speakers compatible with bi-amp connections. • When making bi-amp connections, be sure to remove the short- circuiting plate or wire between the speaker's woofer and tweeter terminals.
