Operation Manual
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.
