FUNCTIONAL DESCRIPTION

• Compressor/Limiter. The main application for this effect is that of a limiter, since it

is a compressor that only acts above the previously set threshold level. Below the

threshold level, the signal will only be affected by the gain that is applied. When you

use this effect as a limiter, we recommend adjusting the gain to 0 dB, the

compression range to the maximum (1:50) and the threshold to the level above

which you wish to limit the signal (typically between 0 and +6 dB). The adjustments

to the “Attack“ and “Release“ time are described in greater depth in the configuration

software manual. “Gain“ parameter settings above 0 dB are appropriate for very low

compression threshold settings. This makes it possible to have a uniform level for a

background sound—typically, the international sound of an event broadcast.

• Noise Gate. The noise gate is an expander that acts below a certain threshold level,

drastically reducing the levels below that threshold. This allows the background

noise in a given signal to be eliminated. When the noise gate is used with voice

signals, you will need to be especially careful when adjusting the times (“Attack“,

“Release“, “Hold“) so as not to cut off the beginnings or ends of utterances.

In the Process Menu screen you can manage groups of presets for the signals selected.

For the preset group of each one of these effects, the action options associated with

each of the pushbuttons (21) are as follows:

• Scroll: Lets you select a type of effect from the list described above, either to access

the configuration parameters for the active preset or to access the list of presets for

the selected effect.

• Enter: Gets you into the preset parameter adjustment window for the currently active

preset.

• Presets: Allows you to access the modification of the list of presets ONLY of the

effect selected in the list, with the following options:

 Scroll. Enables you to select a

preset from the ones displayed in

the list.

 Enter. Accesses the selected

preset.

 Change Active. Use this option

to change the active preset; that

is, the one that is modified,

activated or deactivated when

you act on the relevant controls.

 On/Off. Activates or deactivates

the effect.

 Save/Load selected. To save or load an effect, the following options are
