USE EXAMPLE:
1. Set
THRESHOLD
to a level lower than 0 dB (e.g. –15 dB).
2. Set RATIO (i.e. 4:1).
3. Adjust OUT GAIN in order to increase the signal output gain (to minimize the
compressor attenuation, i.e. +10 dB).

AUTOMATIC GAIN CONTROL (AGC)
The automatic gain control does not modify a signal having a level lower than the
predetermined threshold, but increases or reduces a signal above the threshold to
get the desired average level (‘target’), within the set time and according to the
compression/expansion ratio.
To access AGC parameters (of a single input), click
EDIT
on the respective channel
and select the
INPUT DSP
window.
THRESHOLD
: adjusts the level above which the AGC operates.
TARGET : adjusts the optimal average signal level to be obtained.
Time : adjusts the AGC intervention time.
Ratio : sets the ratio between the original signal (above the threshold) and the AGC
output.
Use a ratio in the 1.5 ÷ 3 range, in order to avoid excessive compression / expansion,
which may lead to too low or distorted output signals.
A 1:1 ratio is an invalid setting, as the AGC does not operates at all.
Enable
: toggles the AGC (keep it on when using).
