5 Band Page
5 Band Compressor Fader Groups
The following parameter groups and X-Over settings are
easily selected and assigned to the Faders pressing the
individual buttons.
• Threshold
• Gain
• Steer (DXP mode)
• Attack
• Release
• X-overs
All parameters
Selecting one of the “All” parameters enables you to adjust
parameters for all bands simultaneously relative to their
individual settings.
Defeat Threshold
If too much noise is brought up by Gain in the 5 Band
section, a Defeat function is available to revert to unity gain
a certain number of dB below the threshold. Turn on or off
this function by setting the Defeat Ratio. Example: If the
Reference Level is set at -8 dBFS, 5 Band Threshold at -15
dB and Defeat Threshold at -17 dB, gain above 0 dB in
the 5 Band section will be defeated below -40 dBFS.
Defeat Ratio
In the above example, the slope with which MD4 reverts
to unity gain below -40 dBFS is determined by the Defeat
Ratio. For sensitive material with information in the vicinity
of the Defeat Threshold, Defeat Ratios between 1:1.03 and
1:2 will be best suited in combination with a Look Ahead
Delay of at least 1 ms.
Steer parameter
(DXP mode)
DXP processing enables boost of only low level material
without affecting material that is already loud enough. This
gives less audibility and less transient distortion. The boost
is applied to levels below the Reference level, and reaches
its max at Threshold. The more Steer, the more audio is
steered towards Ref Level.
MD4 features different Steer in all 5 bands if so desired.
For more information about this parameter, see the
previous description of DXP Mode.
Limiter Page
Brickwall Limiter
To exploit MD4’s 48 bit signal path, the output includes
a Brickwall 2 Limiter with upsampling and selectable,
adaptive profiles. For more information about the Limiter,
please consult the Brickwall 2 pages in this manual.
Soft Clip L - Soft Clip R
Range: -3, 0, +3, +6dB, Off
When active, Soft Clip applies a saturation effect on signals
close to maximum Output level. This controlled distortion
of transients works well for adding loudness. While the
Brickwall Limiter is extremely low distortion, Soft Clip is not.
Use your own judgement if you want it or not.
Threshold L - Threshold R
Range: -12 to 0 dBFS
Output Limiter Thresholds. Consider linking L and R when
used on stereo signals. Soft Clip threshold is relative to this
setting.
Profile
Various profiles can be selected to best suit your material
to process: Voice, Loud, Universal, Soft and Dynamic.
Depending on your object for your particular session and,
of course, your individual preferences you may find that
with the different profiles you can shape you mix to be;
- “loud” by using the pop/rock setting, which pumps up the
release time fairly fast (though still adaptive)
- or “aggressive” by swamping more transients
- or use the “universal” or “acoustic” settings that tend to
sound more natural and result in more natural transients
