Controls
Both channels of the mpressor are absolutely identical regarding their electronic design. Therefore
both sides of the front panel have exactly the same controls and switches. Continuative informa-
tion on the specific functions can be found on the pages in brackets.
Threshold: the operating point of the compressor. If the input level exceeds the value set
with this controller, the compression process will start. (p. 18)
SC Extern: an additional input for the sidechain. If this function is active, a signal that is fed
into the corresponding input connector controls the compression process. (p. 9)
Attack: the transient response of the compressor. It determines the time the mpressor needs
to reach 10 dB of gain reduction. (p. 19)
Auto Fast: a semi-automation. This function shortens the attack time automatically on fast
and loud signal impulses. (pp. 10, 19)
Release: the return phase of the compressor. It controls the period of time between when
the input signal falls below the threshold and the mpressor’s return to unity gain. (p. 20)
Anti Log: an alternative characteristic of the release curve. This function switches from a
linear to an antilogarithmic progression. (pp. 10, 20)
Ratio: the relation between the input level and the output level. As a specialty of the mpres-
sor, even negative ratios can be set here. (p. 21)
Gain Reduction: the display for the gain reduction. Shows the amount of compression mea-
sured in dB as an optical support for the acoustic events. (p. 9)
EQ Gain: the characteristic of the Niveau Filter. Between the mid and fully counter-clockwise
position, bass is boosted and treble is cut (vice versa in the other direction). (pp. 11, 22)
On: activates the Niveau Filter. In the signal path, this special EQ is placed after the compres-
sor section, thus it will not influence this section’s behavior. (p. 11)
