59/3@&OCPPL 1BHF  8FEOFTEBZ 0DUPCFS Connecting the TX-NR901-Continued Connecting Your Speakers Read the following before connecting your speakers: • Disconnect the power cord from the wall outlet. • Read the instructions supplied with your speakers. • Pay close attention to speaker wiring polarity. In other words, 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. • Only connect speakers with an impedance of between 4 and 16 ohms. If the impedance of any one speaker is between 4 and 6 ohms, be sure to select the 4 ohms setting on the TX-NR901 (see page 40). • 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 TX-NR901. • Don't connect more than one cable to each speaker terminal. Doing so may damage the TX-NR901. • If you want to connect a single speaker instead of a pair, don't connect it to the left and right terminals.
