Connecting the AV Receiver—Continued
The FRONT L/R and SURR BACK L/R terminal posts
can be used with front speakers and surround back
speakers respectively, or bridged together to provide
almost double the output power for the front speakers.
When bridging is used, the AV receiver is able to drive
2 speakers in the main room (2.1 speakers if you’re
using a powered subwoofer).
For bridging, the positive (+) FRONT L/R and SURR
BACK L/R terminal posts are used, but the negative
(–) FRONT L/R and SURR BACK L/R terminals are
not.
Once you’ve completed the bridging connections
shown below and turned on the AV receiver, you must
set the “Speaker Type: Front(Speaker A)” setting to
“BTL” to enable bridging (see page 61).
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.
