The
DSP-2040
's “D-Max” limiter predelays the
sidechain signal, resulting in a “zero overshoot” limiter,
which is able to catch all peaks and provide a reliable
absolute maximum setting for the output of any
channel.
The predelayed sidechain is shown in green, with
the main signal in red. As the main signal arrives slightly
after the sidechain, the output from the unit does not
suffer from the overshoot problem.
Remember that this delay is only in the order of
tens of uS,and is a predelay – the sidechain is moved
back in time in relation to the main signal. Inserting a
delay into the main signal path of an analogue dynamics
processor will achieve similar results, but with the
penalty of delaying the main signal by the amount of
look ahead delay introduced.
The “D-Max” limiter which appears in output lists just following the traditional limiter, has only two
parameters to adjust:
Op1 Output 1 ClipLim
Rel. = Medium 10dB Above
The release time (either Fast, Medium, or Slow) and the threshold. Note that the threshold is set to be a
minimum of 2dB above the threshold of the program limiter – setting the threshold to 10dB Above, as in the
example, means that no more than 10dB of overshoot above the threshold of the program limiter will ever be
allowed.
The release time may also be set to follow the High Pass filter of the output – this is achieved through the
Design a Crossover sub-menu, and will result in the display changing to show
Op1 Output 1 ClipLim
Rel. = Auto 10dB Above
