Connecting the A-9755/A-9555
Speaker Connection Precautions
You can connect one or two sets of speakers (A/B) to
the A-9755/A-9555, and select which set outputs sound,
or use both sets at the same time.
For both speakers A and B, make sure to connect them
with Left and Right in pairs. If you connect either Left
or Right channel alone, no sound output will be avail-
able. If the electrical contact is poor for the connection,
the Volume indicator will flash quickly when the power
is supplied.
• Connecting one set of speakers (A or B): Only con-
nect speakers with an impedance of 4 ohms or more
but less than 16 ohms. If you use speakers with a
lower impedance, and use the A-9755/A-9555 at high
volume levels for a long period of time, the built-in
protection circuit may be activated.
• Connecting two sets of speakers (A and B): Only
connect speakers with an impedance of 8 ohms or
more but less than 16 ohms. If you use speakers with
a lower impedance, and use the A-9755/A-9555 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.
• Be careful not to short the
positive and negative wires.
Doing so may damage the
A-9755/A-9555.
• Don’t connect more than one
cable to each speaker termi-
nal. Doing so may damage
the A-9755/A-9555.
• Don’t connect a speaker to more than one pair of
speaker terminals.
Connecting the Speaker Cables
The following illustration shows which speaker should
be connected to each pair of terminals.
Connecting Your Speakers
1
Strip about 15 mm (5/8
inch) 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.
