4.3 Indicators

4.3.1 On / Failure Indicators

Under normal operation, after the amp has started, the green power LEDs are permanently lit. A variety of different sequences of flashing LEDs are used to indicate other operating states and errors in one of the channels of the power amp. (See 6.0,Trouble Shooting)

4.3.2 Signal Indicators

The green signal LED is illuminated when the voltage level at the output reaches approx. 4 V; this corresponds to a power of approx. 4 W at an impedance of 4 Ohms.

4.3.3 Clip / Output Current Indicators

The clip LED’s are bi-coloured: green / red. Each colour indicates a different status.

The green section is subject to analogue control. The brightness is proportional to the output current in the channel. The LED is visibly lit above around 1 Amp, while full brightness corresponds to the maximum rated current. If the LED is lit red only, no load is applied to the outputs or Clip is active with a duty cycle of more than 10 %.

When under load, there is also a certain current that flows when controlling the power level; the green section will be lit appropriately. If the power level is taken to the limit, the green and red sections will appear mixed, resulting in a shade of yellow that depends on the current. If the microprocessor detects a clip signal with a duty cycle of more than 10 % within a time interval of 50 ms, then it suppresses the green section so that the clip LED appears only red. Careful analysis of the various dependencies when comparing channels that are subject to identical control (possibly in several different power amps) will allow conclusions to be drawn about the inherent impedances. This can aid the detection of incorrectly wired components and faults in loudspeakers at an early stage.
