Especially the release time of the control circuit has more influence to the
increase of loudness as any other parameter. The ranging of time constants in
processing time groups reflects this fact. The range for processing time shows
influence on release time parameter mostly.
The selection of the parameter limiter PROCESS changes the range of time
constant values as follows:

The audio signal delay through the dynamics processor is approx. 2ms due
to delaying of the audio signal using internal memory. A small delay is
deliberately introduced to the audio signal in order to allow limiter and
compressor algorithms which can 'preview' the audio signal before
changing it. That is the signal curve can be changed before maximum level is
reached. This delay must be considered before attempting to mix signals
processed by the dynamics processor with other undelayed signals.
When mixing together a delayed signal and a direct signal there may be
cancellation of the signal waveform at some frequencies and re-inforcement
of the waveform at other frequencies (comb filter effect). Corresponding
2ms delay of direct signals should therefore be carried out before mixing
them with delayed processed signals.
