K Series Power Amplifiers

6 Troubleshooting

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: 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 Clip LED to flash constantly.

• Load is wired incorrectly or Bridge Mono Switch is set incorrectly. Check both.

Note: If sound is distorted but clip LED is not flashing, check mixer levels and gain staging, mixer clip lights, and pads built into micro- phones.

CONDITION: Input signal but no sound.

POSSIBLE REASON:

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

•Speakers not connected.

CONDITION: No input signal.

POSSIBLE REASON:

•Input signal level is very low.

•Level controls are turned down.

•Input cables are not connected.

CONDITION: TLC indicator glows brightly.

POSSIBLE REASON:

•The amplifier is protecting itself with the thermal level control system. Turn on a fan or turn down the level controls.
