Connecting the AV receiver-Continued Using Dipole Speakers You can use dipole speakers for the surround left and right, surround back left and right speakers. Dipole speakers output the same sound in two directions. Dipole speakers typically have an arrow printed on them to indicate how they should be positioned. The surround left and right dipole speakers should be positioned so that their arrows point toward the TV/screen, while the surround back left and right and front high left and right and front wide left and right dipole speakers should be positioned so that their arrows point toward each other, as shown.

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" (see page 51). 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. • If you use 4 or 5 speakers, connect each of the two surround speakers to the SURR/ZONE 3 L/R terminals. Do not connect them to the SURR BACK/ZONE 2 L/R, FRONT WIDE L/R, or FRONT HIGH L/R terminals. • 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. • Don't connect more than one cable to each speaker terminal. Doing so may damage the AV receiver. • Don't connect one speaker to several terminals. 19
