Connecting the AV receiver—Continued
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 respec-
tively, 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(FrontB)” setting to “BTL” to
enable bridging (see page 57).
When front Speakers B are bridged, front Speakers A
must be wired normally.
Notes:
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 speak-
ers can handle the additional power.
