OMICRON ISSUE 2 DEC ‘98

PROTECTION CIRCUIT

A special circuit in the Classé OMICRON continuously monitors the output audio signal to

detect output overload, clipping or DC content. In addition, each channel has two front end supply

voltage fuses, located on the front end voltage regulation board, to protect the input circuitry from

damage due to overload. There is a green LED for the negative voltage supply and a red for the

positive. If a fuse fails, the corresponding LED goes out, alerting you of the fact. (These fuses are 1

amp fast blow).

There are also line AC fuses, located at the rear of the amplifier immediately above each IEC

receptacle. There are no LEDs monitoring the condition of these fuses.

If the protection circuit of the unit is triggered or any of the fuses has blown, the FRONT

PANEL POWER LED(S) will go to BLINKING GREEN, indicating a “fault” condition. If the left

LED is BLINKING GREEN, the fault condition should be located at the left channel, if the right

channel LED is BLINKING GREEN, the fault will be located to the right channel regardless if the

unit is used in mono or stereo.

IF THE PROTECTION CIRCUIT HAS BEEN TRIGGERED, TURN THE OMICRON

OFF. .After the situation which has triggered the protection circuit has been clearly identified and

corrected, attempt to re-start the unit. IF THE UNIT STILL GOES INTO PROTECTION MODE,

OR IF IT APPEARS THAT PROTECTION FUSES DID BLOW, CONTACT YOUR LOCAL

DEALER. DO NOT

TRY TO CHANGE A BLOWN FUSE. REPLACING A FUSE WITHOUT

CHECKING FOR COMPONENT FAILURE COULD RESULT IN FURTHER, SERIOUS

DAMAGE TO VITAL COMPONENTS IN YOUR AMPLIFIER. CONTACT YOUR LOCAL
