10. THE LED INDICATOR FOR POWER, FAULT, PEAK, SIGNAL AND LEVEL

When the Power Audio Amplifier's power switch is turned on, the POWER LED will be illumed, so the user may be aware of it. When the FAULT LED is illumed, means the device is damaged, so you must stop using it.

The PEAK indicator circuit monitors the output signal level. When it illuminates, means that the gain or EQ boost should be reduced.

The signal LED lights when the output signal level reaches approximately -30dBu. 10-segment LED METER monitors output signal level.

11. POWER SWITCH

Depressing the power switch supplies power to the power amplifier.
