Connecting Your Speakers - Onkyo TX-NR901 Instruction Manual

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 nega-
tive (–) 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 termi-
nal. 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.
