COMPANDER HARD (H)
COMPANDER SOFT (S)
The hard and soft companders combine the effects of the compressor, expander and limiter.
The companders function differently at the following levels:
1
0 dB and higher.....................................Functions as a limiter.
2
Exceeding the threshold .......................Functions as a compressor.
3
Below the threshold and width............Functions as an expander.
The hard compander has an expansion ratio of 5:1, while the soft compander has an expan-
sion ratio of 1.5:1. The expander is essentially turned off when the width is set to maximum.
The compressor has a fixed knee setting of 2.
* The gain is automatically adjusted according to the ratio and threshold values, and can
be increased by up to 18 dB.
* The OUT GAIN parameter enables you to compensate for the overall level change
caused by the compression and expansion processes.

Description
This determines the level at which compression is
applied.
This determines the amount of compression.
This determines how soon the signal is com-
pressed or expanded once the compander has
been triggered.
This determines how soon the compressor or
expander returns to the normal gain once the
trigger signal level drops below or exceeds the
threshold respectively. The value is expressed as
the duration required for the level to change by
6 dB.
This sets the compander's output signal level.
This determines how far below the threshold
expansion will be applied. The expander is acti-
vated when the level drops below the threshold
and width.
