Connecting the A-9355/A-9155
Speaker Connection Precautions
You can connect one or two sets of speakers (A/B) to
the A-9355/A-9155, 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 both speaker sets to terminal A and B
respectively to deliver sound at the same time, 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-9355/A-9155 at
high volume levels for a long period of time, the
built-in protection circuit may be activated.
• If you use speakers with an impedance of 4 to 8
ohms, connect them to either terminal A or B, or oth-
erwise do not use both speaker sets simultaneously to
deliver sound.
• 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.
Make sure also the wires do
not touch the rear panel.
Doing so may damage the
A-9355/A-9155.
• Don’t connect more than one
cable to each speaker terminal. Doing so may damage
the A-9355/A-9155.
• 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.
