COMPRESSOR
The compressor reduces the dynamic range of audio signals. Once the signal exceeds a certain
threshold, the signal gets compressed, i.e. major input level changes result in minor output level changes. Narrowing
the dynamic range often allows for easier recording or mixing the audio signal. Two compressors are available for each
UI-1 Universal Input Module.

FREQ (frequency) sets the center frequency of a parametric
EQ or the cut-off frequency of shelving and Hi / Lo pass
filters.
Q or BW defines the quality or bandwidth of a parametric EQ.
A high Q-value results in a narrowband filter, while a small Q-
value results in a broadband filter. The Q-value also sets the
quality and thus the response of Hi, Lo and All pass filters
with slopes of 12dB/ oct.
SLOPE sets the steepness or filter-order of low or high
shelving equalizers and low or high pass filters. Setting
different slopes within the transmission range is possible.
That, in conjunction with the Q-parameter, offers the
possibility for a hi-pass filter to be programmed for B6-
alignment, which describes a drastic rise in the cut-off
frequency range.
BYPASS switches the corresponding filter ON (not engaged)
or OFF (engaged), which allows for quick A / B-evaluation of
the actual effect that a filter has on the sound.
Description
THRESHOLD defines the signal level at which the
Compressor sets in. Entering the desired value is
possible in dBu as well as in V. The entered value is
automatically converted in both directions.
