Connecting the AV receiver-Continued Bi-amping the Front Speakers A The FRONT L/R and SURR BACK/ZONE 3 L/R terminal posts can be used with front speakers and surround back speakers respectively, or bi-amped to provide separate tweeter and woofer feeds for a pair of front speakers A that support bi-amping, providing improved bass and treble performance. • When bi-amping is used, surround back speakers can- not be used. • For bi-amping, the FRONT L/R terminal posts con- nect to the front speakers' woofer terminals. And the SURR BACK/ZONE 3 L/R terminal posts connect to the front speakers' tweeter terminals. • Once you've completed the bi-amping connections shown below and turned on the AV receiver, you must set the "Speakers Type(FrontA)" setting to "Bi-Amp" to enable biamping (see page 57). • When front Speakers A are biamped, front Speakers B must be wired normally or not used. Important: • When making the bi-amping connections, be sure to remove the jumper bars that link the Speakers' tweeter (high) and woofer (low) terminals. • Bi-amping can only be used with speakers that support bi-amping.
