Troubleshooting

If the PA-MC5500 fails to function normally, first check

the following points before contacting your Onkyo

dealer. If the problem is not solved after going through

the following list, unplug the power cord and contact

your Onkyo dealer.

No power.

• Power cord is not correctly plugged into AC outlet/

Inlet.

→ Plug the power cord into the AC outlet/Inlet prop-

erly.

• POWER switch is not set to ON position.

→ Set the POWER switch to ON.

Power turns on but no sound.

• Incomplete connections.

→ Check speaker cable connections.

→ Insert all plugs firmly into jacks.

• No input signal from control amplifier.

→ Check for input signal from control amplifier.

• Incorrect INPUT SELECT switch setting.

→ Set INPUT SELECT switch to correct setting.

The STANDBY indicator flashes red.

• The protection circuitry has been activated.

→ Remove the power cord from the wall outlet

immediately. Set the POWER switch to OFF, discon-

nect all speaker cables and input sources, and then

leave the amplifier with its power cord disconnected

for 1 hour. After that, reconnect the power cord, set

the POWER switch to ON. If the amplifier stays on,

disconnect the power cord, and reconnect your

speakers and input sources. If the amplifier turns off,

disconnect the power cord, and contact your Onkyo

dealer.

The 12V trigger of the PA-MC5500 does not

react to that of the PR-SC5507.

• Connection between the 12V trigger terminals is

incomplete.

→ Connect the cables to the terminals firmly.

Humming or other noise is heard.

• Input cable connection is incomplete.

→ Insert the input cable to pin jack or connector

completely.

• Noise from power cord or power transformer affects

the input cable.

→ Keep power cord or power transformer away from

the input cable.

• Power cord or speaker cables are bundled together

with pin cords.

→ This may cause humming or noise. Do not bundle

power cord or speaker cables with pin cables

together.

• Connection to the input terminals is not complete or

not appropriate.

→ For each channel’s input terminals, connect cables

or cords to either balanced input terminal or audio

input terminal only and switch the INPUT SELECT

switch accordingly.

Avoid connecting the cables or cords to the input ter-

minals that will not be used.
