Bridging the Front Speakers B

Right speaker

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 bridged together to provide almost double the output power for the front speakers B.

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

•For bridging, the positive (+) FRONT WIDE/ZONE 2 L/R

and SURR BACK/ZONE 3 L/R terminal posts are used, but the negative (–) FRONT WIDE/ZONE 2 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 Type(Front B)” setting to “BTL” to enable bridging (➔ 51).

Left speaker

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

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.

Connecting a Power Amplifier

If you want to use a more powerful power amplifier and use the AV receiver as a preamp, connect it to the PRE OUT

jacks, and connect all speakers to the power amplifier.
