Connecting Your Speakers-Continued Bridging the Front Speakers (TX-SR875 only) 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 setting to BTL to enable bridging (see page 45). 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 speakers can handle the additional power.

Connecting Your Speakers
—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 setting to BTL to enable bridging
(see page 45).
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.
