2.2 The LED indicators
The figure below shows the front panel of DIGAM L Series. and refers to a single couple of channels. The clip LED, when
lighting, indicates the clipping state for the output stage of the correspondig channel. The signal, -18dB and -6dB LEDs
operate as V-meter and the signal LED is lighted when the signal is present in the input stage of the correspondent
channel. The "ready" LED, when lighted, indicates that the startup time after power-on is finished and the amplifier is
ready to use. The "temp" LED, when lighted, indicates that the output stage of the corresponding channel is reducing the
output power due to an over-heated state.
