Connecting the AV receiver—Continued

Bi-amping Front Speakers (TX-SR577 only)

The FRONT L/R and SURR BACK L/R terminal posts can be used with front speakers and surround back speakers respectively, or bi-amped to provide separate tweeter and woofer feeds for front speakers, providing improved bass and treble performance.

When bi-amping is used, the AV receiver is able to drive up to 5.1 speakers in the main room.

For bi-amping, the FRONT L/R terminal posts connect to the front speakers’ woofer terminals. And the SURR BACK L/R terminal posts connect to the front speakers’ tweeter terminals.

Once you’ve completed the bi-amping connections shown below and turned on the AV receiver, you must set the “Sp Type” setting to “Bi-Amp” to enable bi- amping (see page 40).

Important:

When making the bi-amping connections, be sure to remove the jumper bars that link the speakers’ tweeter (high) and woofer (low) terminals.

Bi-amping can only be used with speakers that support bi-amping. Refer to your speaker manual.
