Compression,Expansion and Limiting￿￿￿￿

The act of compressing a signal inevitably causes an increase in noise level. Compression reduces peak levels; gain make up restores the overall level, and in the process increases the level of any background noise that the signal contains.

Almost always, when compression is used, the Expander section of the DN500 Plus will be used also, to clean up the signal. The Limiter/Clipper will control any unwanted peaks.

The result is three-stage dynamic control over gain with three different threshold levels:

Limiter Threshold

+20

+10

leOutput (dB)vel

Compressor Threshold

Input level (dB)

-20

-10

+10

+20

Expander Threshold

-10

-20

In the mid-range of levels, the signal is unaltered. Above the compression threshold, in this example, gain is reduced by a ratio of 2:1. Above the limiting threshold it is reduced by 25:1. At levels below the Expander threshold, gain is reduced by 2:1. Complete control over signal dynamics is possible.
