Wide-band AGC

One of the main processing functions of the SOUND4 STREAM X is the Wide Band AGC -

automatic gain control, operating in broad band. Its main purpose is to “even out” gaps of levels

in terms of processing.

The algorithm which was especially developed for this AGC is of the predictive type. It allows

very high sound variations without any sort of pumping. Compared with other processors, control

of the input gain is greatly facilitated.

The first processing stage is AGC - automatic gain control that works across large band of

frequencies. It is intended to bring to normal the differences in the audio levels applied at the input.

It corrects strong sound variations without pumping effects.

Gate Threshold

– When the audio drops below the user-defined limit, the threshold will freeze

the processors’ operation. This function limits the floor noise when the signal is low.

Drive

– increases or decreases the gain at the AGC input. Increasing the drive will make up

for very low levels, and decreasing it (very low drive) will prevent low level corrections at the

processor input.

Attack

– To adjust the AGC reactivity speed to a volume increase, adjust the attack in dB per

second.

Release

– sets the AGC correction speed in dB per second. As the AGC itself is very powerful

tool, it is not necessary to use high Release speeds. For example, we recommend using 1 and 1.5

for classical music and 2 for other programs.

Tone-FX

Enriches the sound color before dynamic processing. There are two modes - Basic and Advanced

Tone FX. The spectral display (placed on the left of the settings) illustrates in real time the general

correction applied by the parametric equalizer.

Basic Tone FX

In this mode the only adjustable options are:

- For Fat EQ, Low EQ, Mid EQ, High EQ is the gain;

- For Bass FX only one effect variable is available.

Advanced Tone FX

All the parameters of the parametric equalizer are available In Advanced Tone FX mode:

Freq

– Parametric band center frequency;

– Applied filter quality (parametric band “width”);

Gain

– Gain of the parametric band.
