Connecting the AV Receiver—Continued
Speaker Connection Precautions
Read the following before connecting your speakers:
• North American/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 imped-
ance 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 43). 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 nega-
tive (–) 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 L/R terminals. Do not
connect them to the SURR BACK 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.
Connecting the Speaker Cables
FRONT HIGH L/R, ZONE 2 L/R
(North American/Taiwan models)
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.
2
Unscrew the terminal.
3
Fully insert the bare
wires.
4
Screw the terminal tight.
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.
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.
