Connecting the AV receiver
—Continued
The FRONT L/R and SURR BACK/ZONE 3 L/R ter-
minal posts can be used with front speakers and surround
back speakers respectively, or bridged together to pro-
vide 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 Type(FrontA)” setting to “BTL” to
enable bridging (see page 57).
• When front Speakers A are bridged, front Speakers B
must be wired normally or not used.
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.
