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 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.
