Connections
Connecting Your Speakers
You can connect one or two sets of speakers (A/B) to
the A-9377 and select which set outputs sound, or use
both sets simultaneously.
Speaker Connection Precautions
•Always connect speakers in pairs.
• If you want to output sound from speaker sets A and B
simultaneously, you must use speakers with an impedance of 8 to 16 ohms. If you connect speakers with a
lower impedance, and use the A-9377 at high volume
levels for a long period, the built-in protection circuit
may be activated.
• If your speakers have an impedance of 4 to 8 ohms,
connect them to either the SPEAKERS A or SPEAKERS B terminals, or do not output sound from both
speaker sets simultaneously.
• 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 negative (–) 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-9377.
• Do not connect more than one
cable to each speaker terminal. Doing so may damage
the A-9377.
• Do not connect a speaker to more than one pair of
speaker terminals.
Connecting the Speaker Cables
Strip about 15 mm (5/8 in.)

Troubleshooting
If you have any trouble using the A-9377, look for a
solution here. If you cannot resolve the issue yourself,
contact your Onkyo dealer.
Power
Cannot turn on the A-9377.
• Make sure that the power cord is properly plugged into
the wall outlet.
• Unplug the power cord from the wall outlet, wait ten
seconds or more, then plug it in again.
The SPEAKERS A and B indicators are both flashing.
• The amp protection circuit has been activated. Set the
POWER switch to OFF immediately, remove the
power cord from the wall outlet, and contact your
Onkyo dealer.
Audio
There’s no sound or it’s very quiet.
• Make sure that all audio plugs are pushed in all the
way (page 12).
• Make sure that the inputs and outputs of all components are connected properly.
• Make sure that the polarity of the speaker cables is
correct and that the bare wires are in contact with the
metal part of each speaker terminal (page 11).
• Make sure that the correct input source is selected
(page 16).
• If the MUTING indicator is flashing, press the remote
controller’s [MUTING] button to unmute the A-9377
(page 16).
• Make sure that none of the cables are bent, twisted, or
damaged.
• If your turntable uses an MC type cartridge, you must
use an MC head amp or MC transformer (page 12).
• Make sure the SPEAKERS selector is set correctly. If
it’s set to OFF, no speakers will output sound
(page 15).
Noise can be heard.
• Using cable ties to bundle audio cables with power
cords, speaker cables, and so on may degrade the
audio performance, so do not bundle them together.
• An audio cable may be picking up interference. Try
repositioning your cables.
The tone controls have no effect.
• If the TONE/DIRECT indicator is on, the Direct function is on and the tone controls have no effect. Press
the [TONE/DIRECT] button to turn the function off.
The TONE/DIRECT indicator will go off (page 16).
Remote Controller
The remote controller doesn’t work.
• Make sure that the batteries are installed with the correct polarity (page 10).
•Try installing new batteries. Do not mix different
types of batteries or old and new batteries (page 10).
• Make sure that the remote controller is not too far
away from the A-9377 and that there’s no obstruction
between the remote controller and the A-9377’s
remote control sensor (page 10).
• Make sure that the A-9377 is not subjected to direct
sunshine or inverter-type florescent lights. Relocate if
necessary (page 10).
• If the A-9377 is installed in a rack or cabinet with colored glass doors, the remote controller may not work
reliably when the doors are closed (page 10).
Cannot control other components?
• If it’s an Onkyo component, make sure that the
cable and analog audio cable are connected properly.
Connecting only an cable will not work. (page 14)
The A-9377 contains a microcomputer for signal
processing and control functions. In very rare
situations, severe interference, noise from an
external source, or static electricity may cause it
to lock up. In the unlikely event that this happens,
unplug the power cord from the wall outlet, wait
at least ten seconds, and then plug it back in
again.
Onkyo is not responsible for damages (such as
CD rental fees) due to unsuccessful recordings
caused by the unit’s malfunction. Before you
record important data, make sure that the material will be recorded correctly.
