Bridging Front Speakers A - Onkyo TX-NR905 Instruction Manual

Connecting Your Speakers—Continued

Bridging Front Speakers A

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 A setting to BTL to enable
bridging (see page 51).
• 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.
