LED INDICATORS

The LED indicators can be used to monitor system operation and identify common problems.

POWER: A single GREEN LED, on left side of Gain Control group.

Normal indication: AC switch ON: LED will illuminate.

If no indication: Check AC power cord and AC outlet. Confirm that DataPort 1-2 is not holding the amp in 'Standby' mode.

CLIP: RED, to the right of each Gain control.

Normal indication: illuminates whenever the amplifier is driven beyond full power. The resulting distortion corresponds to the brightness of the LED. Distortion that causes only brief flashing may not be audible.

-During muting, the LED fully illuminates. This occurs during normal "On-Off" muting.

Abnormal indication:

-Bright red illumination while the amp is being used indicates either thermal muting or a shorted output.

-If the amplifier overheats, the fan will run at full speed, and operation should resume within one minute. Allow the fan to run, and make sure the amplifier ventilation is ade- quate.

-A shorted or overloaded output circuit will cause excessive Clip flashing and possible overheating.

If distortion is audible without a Clip indication, the problem is either before or after the amplifier. Check for damaged speakers or overloaded signal source. The amplifier Gain control should be in the upper half of its range to prevent input overload.

SIGNAL: GREEN, under each Clip LED.

Normal indication: illuminates when the input signal exceeds -35 dB. As signal approaches full power, the LED will illuminate continuously.

If no indication: check Gain settings and increase gain if necessary. Check input connec- tions and audio source for signal. If the Clip LED illuminates with little or no Signal indi- cation, check the output wiring for shorts.

Abnormal indication: If the Signal LED illuminates with no signal input, there may be system oscillations or some other malfunction. Disconnect the load and fully reduce the gain. If the signal LED remains on, the amp may need servicing.

BRDG and PAR : Each channel pair has a YELLOW LED for Bridge Mode, and an ORANGE LED for Parallel mode. These show how the rear panel switches are set (see page 5). In Stereo mode, both LEDs should be OFF.
