Notes: Quick access gain function is only available from the main screen.

Depending on the selected factory preset the output gain might be locked by L-ACOUSTICS

. In that case the LCD

displays a cross (X) instead of a numeric value.

Gain values can be scaled at 0.1dB or 1dB resolution. To obtain 0.1dB resolution, simply rotate the encoder wheel. To

obtain 1dB resolution, simultaneously push and rotate the encoder wheel.

Input, routing and group information

While the main screen is displayed, pressing and holding the IN A or IN B key also provides quick access to important

information.

The selected input mode is displayed. The top right part of the LCD screen in Figure 20 and Figure 21shows that the

ANALOG input mode has been selected (ANA display). The display would be AES for AES/EBU input mode or AFB

for ANALOG FALLBACK mode [7.9.3].

The four bargraph displays show the signal routing between input and output channels in the current preset, and the

input signal level. In Figure 20, OUT 1 and OUT 2 LOAD LED are lit when pressing IN A , indicating that the IN A

input is routed to OUT 1 and 2 output channels. The SIGNAL and -25 dB LED of the first bargraph display are

simultaneously lit to display the level of the signal delivered at IN A input.

If the controller is part of a group [7.8], the group name will also be displayed on the bottom right parts of the screens

when pressing any input key (IN A or IN B). In the example illustrated in Figure 20 and Figure 21, the amplified

controller is assigned to the SUBLEFT group.

Note: The SIGNAL LED is lit when the input voltage reaches -37.8 dBu (10 mV) and the CLIP LED is lit when the

input voltage reaches 22 dBu (9.8 V).
