Bridging 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 speak- ers respectively, or bridged together to provide almost double the output power for the front speakers A.

•When bridging is used, surround back speakers cannot be used.

•For bridging, the positive (+) FRONT L/R and SURR BACK/ZONE 3 L/R terminal posts are used, but the negative

(–)FRONT L/R and SURR BACK/ZONE 3 L/R terminals

are not.
• Once you’ve completed the bridging connections shown below
and turned on the AV receiver, you must set the “Speakers	Right speaker	Left speaker
	Right speaker	Left speaker

Type(Front A)” setting to “BTL” to enable bridging (➔ 51).

•When front speakers A are bridged, front speakers B must be wired normally or not used.

Note

•Use only front speakers with an impedance of 8 ohms or higher for bridging. Failure to do so may seriously damage the AV receiver.

•When using bridging, make sure that your front speakers can handle the additional power.

Bi-amping the Front Speakers B

The FRONT WIDE/ZONE 2 L/R and SURR BACK/ ZONE 3 L/R terminal posts can be used with front wide speakers and surround back speakers respectively, or bi-amped to provide separate tweeter and woofer feeds for a pair of front speakers B that support bi-amping, providing improved bass and treble performance.

•When bi-amping is used, surround back speakers cannot be used.

•For bi-amping, the FRONT WIDE/ZONE 2 L/R terminal

posts connect 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(Front B)” setting to “Bi-Amp” to enable biamping (➔ 51).

• When front speakers B are biamped, front speakers A must be wired normally.
