■ 9.2-channel playback By adding an external amplifier to the 7.2-channel configuration, you can enjoy 9.2-channel playback. Connect your power amplifier's analog audio input jacks to the AV receiver's SB/FH/FW*1 EXT AMP jacks with audio cables. To use the SB/FH/FW EXT AMP jacks, you must specify their channel with the "Preout to External Amplifier" setting (➔ page 64). You can set which speakers you want to use by priority. See "Selecting Speaker Layout" (➔ page 52). *1 SB···Surround Back, FH···Front High, FW···Front Wide Power amplifier Surround back right/ Front high right/ Front wide right Surround back left/ Front high left/ Front wide left Attaching the Speaker Cable Labels The speaker terminals are color-coded for identification purpose.

Then all you need to do is to match the color of each label to the corresponding speaker terminal. Connections Speaker Connection Precautions Read the following before connecting your speakers: • You can connect speakers with an impedance of between 4 and 16 ohms. If the impedance of any of the connected speakers is 4 ohms or more, but less than 6 ohms, be sure to set the minimum speaker impedance to "4ohms" (➔ page 63). If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in protection circuit may be activated. • Disconnect the power cord from the wall outlet before making any connections. • Read the instructions supplied with your speakers. • Pay close attention to speaker wiring polarity. In other words, connect positive (+) terminals only to positive (+) terminals, and negative (-) terminals only to negative (-) terminals. If you get them the wrong way around, the sound will be out of phase and will sound unnatural. • Unnecessarily long, or very thin speaker cables may affect the sound quality and should be avoided. • Be careful not to short the positive and negative wires. Doing so may damage the AV receiver. • Make sure the metal core of the wire does not have contact with the AV receiver's rear panel. Doing so may damage the AV receiver. En-14
