Bridging 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 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).
• 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.
