9. CONNECTING SPEAKERS

ENGLISH

•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 11.

•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 55.)

■Front speakers A and B

•This unit allows you to connect two different sets of front speakers and to select either FRONT A or/and B speakers according to your taste.

•However, if you have only a set of front speakers, connect them to either FRONT A or B speaker terminals.

■Surround back speakers

•When using only one surround back speaker, you should connect it to SURROUND BACK/ROOM 2 LEFT channel.

•If you assign the power amplifier for the surround back/room 2 channels to the ROOM 2, this unit can drive the speakers in another room (ROOM 2).

(For details, refer to “CONNECTING ROOM 2 OUTS” on page 12 and “When selecting the AMP ASSIGN” on page 49.)

Caution :

•For safe amplifier operation, in case of using either front A or front B speakers, use all the speakers with impedance of over 6 ohms. However, in case of using both front A and front B speakers, use only these speakers with impedance of over 12 ohms and other speakers with impedance of over 6 ohms.

•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.
