Connecting the AV receiver-Continued Speaker Connection Precautions Read the following before connecting your speakers: • North American and Taiwan models: You can connect speakers with an impedance of between 6 and 16 ohms. 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 amp protection circuit may be activated. • Other models: 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 "4 ohms" (see page 40). 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 amp 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. Connect positive (+) terminals to only positive (+) terminals, and negative (-) terminals to only 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. • Don't connect more than one cable to each speaker terminal. Doing so may damage the AV receiver. • Don't connect a speaker to several terminals. Connecting the Speaker Cables Terminal posts 1 Strip 1/2"-5/8" (12- 15 mm) of insulation from the ends of the speaker cables, and twist the bare wires tightly, as shown. 1/2"-5/8" (12-15mm) 2 Unscrew the terminal. 3 Fully insert the bare wire. 4 Screw the terminal tight. Push terminals 1 Strip 3/8"-1/2" (10-12 mm) of insulation from the ends of the speaker cables, and twist the bare wires tightly, as shown. 3/8"-1/2" (10-12mm) 2 While pressing the lever, insert the wire into the hole, and then release the lever. Make sure that the terminals are gripping the bare wires, not the insulation. 17
