Operation Manual

mixer.

recep tacle.

The mixer’s high-voltage power supply circuit

fuse has opened. Verify that the AC mains
volt age is correct, then press the Reset button
on the back panel.

If the unit is operated from a 24V DC supply, the

internal fuse may have opened. (The power
switch has no effect on 24V operation.)

POSSIBLE REASON:

Input signal level is too high. Turn down your

input volume controls. NOTE: Your mixer
should never be operated at a level which
causes the Clip LEDS to illuminate constantly.

about 3/4 of maximum level.

CONDITION: No sound.

POSSIBLE REASON:

Check the fuse and replace if necessary, or

return mixer to Crown or an authorized Crown
