1Rack Mounting Ears

Two front-panel mounting holes are provided on each mounting ear.

2Channel Level attenuators

Two input attenuators adjust level for their respective amplifier channels in stereo and in parallel modes. In Bridged Mono mode, the channel A attenuator controls overall signal level for both channels (see rear panel mode switch description).

3Protect

This Red LED indicates that the amp channel is in Protect mode. During Power up, the amp briefly goes into protect mode in order to prevent any loud spikes from being fed to the speakers. After a few seconds the amp comes out of protect mode and is ready for normal operation. If the amp stays in Protect mode, this indicates that there may be a problem internal to the amp. If the amp goes into Protect mode during operation this indicates that either a problem has developed internal to the amplifier or the amplifier is being over-stressed due to an over-current (short circuit or a load impedance below the operating range), or thermal condition. In this event, the amplifier should be switched OFF, and the load connections checked for shorts and proper load impedance. If overheating is suspected, allow the amplifier to cool and check that the airflow is not impeded.

4ACL / IGM

This Red LED illuminates when either the ACL or IGM protection circuitry is engaged. See Section 6,Tourclass Protection for more information on these Crest-exclusive features.

5-24, -18, -6, 0dB

The first three LEDs (-24, -18, -6,) are Green and the last led, 0dB is yellow. These LEDs respond to the incoming program material as peak meters. Under normal operating conditions the Green LEDs illuminate with the dynamics of the program material and theYellow LED flashes during the loudest peaks.

6Signal

Green LED varies in intensity in response to signals below -24 dB.

7Active

Green LED illuminates when the amp is on to show that the channel is active.

8Fan Outlet Grill

CD Series amplifiers are cooled by a single rear-mounted fan.

Cool air flows over the heat sink and exhausts through the front grill. Make sure this outlet remains clear to allow unrestricted airflow.

9Power switch

This switch turns the amp on and off. If the amp doesn’t turn on when the switch is in the ON position, check the circuit breaker on the rear panel.

The power only breaks one side of the AC mains. Hazardous energy may be present in the enclosure when the power switch is in the off position.
