This green LED indicates that AC power is on. 4. Signal Present Indicator. This green LED turns on when the output signal is greater than or equal to approximately -20 dBu (80 mv) at the 4 ohm output. This red LED turns on when the output signal is either beginning to clip or is on the verge of clipping. The level control should be adjusted so the Peak Indicator does not light during normal operation.
