7. CONNECTING SPEAKERS

•Be sure to connect speakers firmly and correctly according to the channel(left and right) and the polarity (+ and -). If the connections are faulty, no sound will be heard from the speakers, and if the polarity of the speaker connection is incorrect, the sound will be unnatural and lack bass.

•For installing the speakers, refer to "Speaker placement" on page 12.

•After installing the speakers, first adjust the speaker settings according to your environment and speaker layout. (For details, refer to "SETTING THE SPEAKER /ROOM EQ SETUP" on page 61.)

■Surround back speakers

•When using only one surround back speaker, you should connect it to SURROUND BACK/MULTI LEFT channel.

•Because this receiver cannot drive the surround back speakers and the ROOM 2 speakers simultaneously, you should assign their power amplifier correctly depending on how to use them. (For details, refer to "CONNECTING ROOM 2 OUTS" on page 13 and "When selecting the AMP ASSIGN" on page 52.)

■Front Bi-Amp Connections.

•Some speakers are equipped with two sets of input terminals, for bi-amplification.

•If no other surround back speakers are used, you can connect the FRONT and the SURROUND BACK/MULTI channels to the bi-amp-capable speakers. (For details, refer to the operating instructions of your bi-amp- capable speakers.)

•To drive the bi-amp-capable speakers, you should assign the power amplifier to "BI-

AMP". ■Note :

•Before making bi-amp connections, remove the short-circuiting bars from the terminals of your speakers.

Caution :

•Be sure to use the speakers with the impedance of 6 ohms or above.

•Do not let the bare speaker wires touch each other or any metal part of this unit. This could damage this unit and/or the speakers.
