7.3.5 PRESET PARAMETERS
The PRESET PARAMETERS menu allows to set preset parameters such as Mute & Unmute, Gain, Delay and Polarity
(when available) of each individual input (IN A & B) and output channels (OUT1 to OUT4).
To access preset parameters, select the PRESET PARAMETERS menu and follow this procedure (see also Figure 19):
1. Turn the encoder wheel to scroll thru one of the seven’s preset parameters.
2. To change the preset parameters to the desired value press and hold the corresponding input or output tab
and turn the encoder wheel (or press the ESC tab to cancel and go back to the last menu).
3. Release the tab when the desired value is obtained.
4. Repeat the procedure to set another parameter (or press the ESC tab to go back to the Main screen).
In the following example the gain of the A input is set to a value of 5.1 dB:
Figure 19: Setting preset parameters
Note: All parameters can be set with 0.1dB or 1dB increments. 0.1dB increments are obtained by simply turning the
encoder wheel. For 1dB increments push and turn the encoder wheel simultaneously.
Although not always displayed, decimal value for Gain and Delay settings are indicated by a dot. For example, ‘‘5’’
stands for the exact value 5, while ‘‘5.’’ stands for a value between 5.1 and 5.9. To see the actual value you must press
and hold the tab corresponding to the selected Input or Output channel.
Depending on the selected factory preset some parameters might be locked by L-ACOUSTICS. In that case the LCD
shows a cross (X) instead of a value.
