7.1.2 Input & Output Gain control
Gain control is also available in quick access mode for both inputs (IN A & B) and outputs (OUT 1 to 4).
From the main screen push and hold the chosen input or output, the LCD will then show the name of the selected
channel and its gain value. Rotate the encoder wheel to set the gain value and simply release the key to go back to the
main screen.

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
shows a cross (X) instead of a value. Scaling gain values can be done by 0.1dB or 1dB step. 0.1dB step are obtained by
rotating the encoder wheel. To obtain 1 dB steps push and rotate the encoder wheel simultaneously .
7.1.3 Front panel Lock / Unlock control
To lock the front panel (even the Mute function) and prevent any unintentional operation simply press and hold both IN
A & IN B tabs simultaneously until the message ‘‘DISPLAY LOCKED’’ is displayed.
To unlock, press and hold both IN A & IN B tabs simultaneously until the message ‘‘DISPLAY UNLOCKED’’ is
displayed.
