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 speak- ers can handle the additional power.
