Simple version SVENSKA NEDERLANDS ESPAÑOL ITALIANO FRANÇAIS DEUTSCH ENGLISH Front A/B connection The second set of front speakers can be connected to the FRONT B/ HEIGHT terminals. In this case, perform the settings using the SPKR A/B button on the remote control or main unit (vpage 27 "Set the front speakers to be used"). NOTE When using the A front speakers and B front speakers simultaneously, make sure you check the impedance of the connected speakers (vpage 5). 2.1-channel connection 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 54) to "SPKR-C". Basic version Advanced version SW FL(B) FL(A) FR(A) FR(B) FL SW FR qw FL (L) q w FR (R) nnFor connecting two subwoofers Two subwoofers can be connected to this unit. The same signal is output from each subwoofer terminal. For surround playback of a multichannel source, if you connect the center speaker, surround speakers, surround back speakers (or front wide speakers) and subwoofers, 7.1-channel playback is available. 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. When making a bi-amp connection, the same signal is output from the FRONT 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. For speaker impedance and speaker cable connections, see page 5. 53 Information
