MD-4
English Manual 105
When set to 0.0 ms, the delay through MD4
caused by additional look ahead structures and
up-sampling, amounts to 38 samples at 44.1 kHz
(0.86 ms), 40 samples at
48 kHz (0.83 ms), 93 samples at 88.2 kHz (1.05
ms) and 98 samples at 96 kHz (1.02 ms).
Crest
Range: RMS, 24 dB, 20 dB, 16 dB,
14 dB, 12 dB, 10 dB, 6 dB or Peak.
Select compression method between RMS and
PEAK for all bands. The dB-steps between RMS
and Peak are number of dBs needed for a peak-
value to override RMS measurement and can be
perceived as a Threshold setting.
Example:
If the Crest parameter is set to 6 dB, the Com-
pressor will respond to RMS values and to peaks
6 dB higher than the current RMS value.

Regardless of sample rate, the Eq in MD4 uses
48 bit, fs/2 analog modeling. You can for in-
stance specify a boost of 3 dB at 28 kHz, even
though the machine may be operating at a sam-
ple rate of 44.1 kHz. What this means is that
the part of the 3 dB boost falling inside the cur-
rent pass-band (0 to 22.5 kHz) will be applied.
Therefore, with the above example, changing the
bandwidth of the 28 kHz boost will result in a no-
ticeable difference.
Note that MS Configuration provides individual
equalization of the M and the S part of the signal,
so you can more surgically access elements of a
complex mix. Because equalization is performed
at 48 bit resolution, MD4 has the headroom to
boost even full scale signals, regardless if pro-
cessing is done in the L/R or M/S domain.

Select A/B
Select which channel to adjust when Mono or
MS Configurations have been chosen. In Stereo
Configuration, the Select key disappears.
Freq
Press and set which frequencies to adjust using
the faders.
Gain
Press and set Gain for the selected frequencies.
Type
Select EQ Type between the following types:
– Notch from 0.02 to 1.00 oct
– Parametric from 0.10 to 4 oct
– Shelve 3/6/9/12 dB/oct
– Bessel or Butterworth Lo and Hi Cut
Note: For traditional shelving response, choose
Shelve 6 dB/oct.
Lo & Hi
Select switch assigning Lo or Hi end frequency
parameters to faders for adjustments.
