Figure 14: The four LED meters

By default the LED meters monitor the state of the four output channels via six LED:

LIMIT/CLIP

The LIMIT/CLIP LED is lit in:

 orange when the limiter is activated (the output voltage is attenuated).

 red when the output voltage reaches the maximum level (signal clip).

The -5 dB, -10 dB and -20 dB LED are lit in green when the output voltage reaches respectively 5, 10

and 20 dB below the maximum level.

SIGNAL

The SIGNAL LED is lit in green when a signal is detected at the corresponding output of the amplified

controller and when the output voltage reaches 0.1 V.

LOAD

The LOAD LED is lit in green when a load is connected and when the output module delivers a

minimum of 0.8 A.

4.2.3 STATUS and L-NET LED

The STATUS LED is lit in:

 green (see Figure 15) when the LA4X operates normally.

 red in case of firmware update or when a fault has been detected in the LA4X circuitry, indicating that a protection

system is active (see Appendix A – Protection systems).

The L-NET LED is lit in green (see Figure 15) when the LA4X is remote controlled from software such as

LA NETWORK MANAGER (refer to the LA NETWORK MANAGER video tutorial).

Front panel commands

The front panel commands remain accessible if the L-NET LED is lit.

4.2.4 OUT LED

The OUTx LED (see Figure 16) is:

 lit (when output channel OUTx is muted.

 not lit (see Figure 16) when output channel OUTx is unmuted.
