MA-5002VZPower Amplifier

6 Troubleshooting

CONDITION: Normal operation.

POSSIBLE REASON:

• This is normal operation for your amp.

• The amp is set for Parallel Mono mode.

CONDITION: Distorted sound.

POSSIBLE REASON:

• Input signal level is too high. Turn down your amplifier level controls. NOTE: Your amplifier should never be operated at a level which causes the Signal/IOC LEDs to constantly indicate an IOC condition.

• ODEP limiting has been activated. Take appropriate measures to keep the ampifier out of ODEP limiting (see Section 5.1.1 for more information about ODEP).

• Output current is being limited because the load impedance of the channel is too low, or the output is shorted.

Key

CONDITION: No power to the amplifier.

POSSIBLE REASON:

The amplifier's Power switch is off.

The amplifier is not plugged into the power receptacle.

The amplifier's low-voltage power supply fuse has blown. Return amp to Crown or an authorized Crown Service Center for servicing.

CONDITION: No sound.

POSSIBLE REASON:

The amplifier has just been turned on and is still in the 4-second turn-on delay.

The amplifier is being held in Standby Mode by an installed IQ PIP module.

The amplifier is in drive protection mode. This can occur with improper source sig- nals like infrasonic square waves or input overloads that excessively clip the input signal.

No input signal

Input signal level is very low.

Level controls are turned down.
