Bargraph display
The four bargraph displays are located on the front panel above the LCD screen (see Figure 23). By default they
monitor the state of each of the 4 amplifier output channel via 6 different LEDs (LOAD, SIGNAL, -25dB, -10dB, -5dB,
CLIP)

LOAD LED
The green LOAD LED is lit when a speaker is connected at the corresponding amplifier channel output. It starts to
illuminate when the output power reaches 2 W.
SIGNAL LED
The SIGNAL LED is lit when a signal is detected at the output of the amplified controller. It starts to illuminate when
the output voltage reaches 100 mV.
dB LEDs
The green “-25dB”, “-10dB”, “-5dB” LEDs are lit when the output voltage reaches respectively 25dB, 10dB, or 5dB
below the maximum level.
CLIP LED
The red CLIP LED is lit when the output voltage reaches the maximum level.

L-NET LED
The yellow L-NET LED is lit when the amplified controller is part of a network and controlled via the
