2.2 The LED indicators
The figure below shows the front panel of channels 1 And 2 of the MA2.8Q. The clip LED, when lighting,
indicates the clipping state for the output stage of the corresponding channel. The signal, -18dB and -6dB
LEDs operate as V-meter and the signal LED is illuminated when the signal is present in the input stage of
the correspondent channel. The "ready" LED, when illuminated, indicates that the start-up time after power-
on is finished and the amplifier is ready to use. The "temp" LED, when lit, indicates that the output stage of
the corresponding channel is reducing the output power due to an over-heated state. The controls and
indicators on channels 3 and 4 are identical.
