PRESET PARAMETERS
The PRESET PARAMETERS menu allows to set preset parameters (Mute & Unmute, Gain, Delay and Polarity [when
available]) of each individual input (IN A & B) and output (OUT1 to OUT4) channels.
To access preset parameters, select the PRESET PARAMETERS menu and follow this procedure (see also Figure 19):
1.
Turn the encoder wheel to scroll through one of the seven preset parameters.
2.
To change the preset parameters to the desired value press and hold the corresponding input or output key *
and turn the encoder wheel (or press the ESC key to cancel and go back to the last menu).
3.
Release the key when the desired value is obtained.
4.
Repeat the procedure to set another parameter or press the ESC key to go back to the main menu.
* Set the input channel parameters by pressing and holding the IN A or IN B tab, even if the key is not located directly
below the value displayed on screen.
In the following example the gain of input A is set at a value of 5.1 dB:
Figure 19: Setting preset parameters
Setting the gain value
Gain values are adjustable between -60dB and +15dB at 0.1dB or 1dB resolution.
To obtain 0.1dB resolution, simply turn the encoder wheel. To obtain 1dB resolution, push and turn the encoder wheel
simultaneously.
Setting the delay value
Delay values are adjustable from 0 to 500ms/171m/561ft for the input channels and from 0
to 35ms/12m/39ft for the output channels. Delay unit can be set in the DELAY UNIT menu (see section 7.3.7).
To obtain one hundredth resolution of the displayed value simply turn the encoder wheel. To obtain one tenth
resolution of the displayed value push and turn the encoder wheel simultaneously.
Notes:
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 bracketed between 5.1 and 5.9. To see the actual value
you must press and hold the key 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
displays a cross (X) instead of a value.
