2.1 Functions of the Expander
As already described, a downward expander automatically reduces the overall level for all signals below an
adjustable threshold and therefore extends the dynamic range of the programme material. The expander therefore
operates in an opposite way to that of a compressor. Expanders generally function with a flat ratio curve, so
that the signal continually fades.
Noice-gates, however, can be seen as a special type of expander. They normally work with a more exaggerated
ratio and radically attenuate the signal if it falls below the threshold.
The following explanations also apply to the gate function, because the gate is a special form
of the expander.
2.2 Interactive control functions
Like the COMPOSER PRO MDX2200, MULTICOM PRO MDX4400, and others, the INTELLIGATE uses the
newly developed INTERACTIVE principle based on a chain of intelligent control functions. For example, the
IRC expander (Interactive Ratio Control) does not use a fixed ratio curve but varies this curve depending on the
input level and the setting of the THRESHOLD control.
The following chapter describes the interactive control functions in full detail:
