Controls - elysia xpressor 500 Mode D'emploi

Controls

Threshold (Thresh): The operating point of the compres-
sor. If the input level exceeds the value set with this controller,
the compression process will start.
Attack: The transient response of the compressor. It deter-
mines the time the xpressor 500 needs to reach 10 dB of gain
reduction.
Release: The return phase of the compressor. It controls
the period of time between the input signal falling below the
threshold and the xpressor 500's return to unity gain.
Ratio: The relation between the input level and the output
level. As a specialty of the xpressor 500, even negative ratios
can be set here. (p. 10)
