Range
This innovative control limits the maximum gain
reduction. It varies from 0 dB (no gain reduction)
to 60 dB possible gain reduction.
This control is very useful when expanding, gating
or keying. If you use the Keying mode (ext, exp,
AVG/PEAK) to, for example, duck a background
music score whenever a narrator speaks, you can set
the Range control to 15 dB to prevent the music to
be reduced by more than 15 dB.
In the original hardware, the
Range
control was only
available in the EXP mode and left out in the LIMIT
mode. This was probably due to implem enta tion difficul-
ties, so we decided to intro duce the
Range
knob to the
other modes as well. (To get the plug-in to beh ave exactly
like the hardware, just set the
Range
knob back to
60 dB in the limit modes.)
Advanced: Range Knob in Limiting Mode (Zones)
When limiting, the Range control gives you a very
powerful tool to create a “zone” in which the limit-
ing occurs. If you for example limit a drum track
and the Gain Reduction meter reads 40 dB in the
peaks, you can set the Range control to 25 dB and
thus get three different zones:
1. No limiting when the drums are below –40 dB
2. Inf:1 limiting in the range –40 dB to –15 dB
3. No limiting for peaks exceeding –15 dB
Knobs
Threshold
Classic threshold control. Determines the signal
level above which Limiting, or below which Ex-
panding action begins.
Variable from –40 dBv to +20 dBv, which in a
plug-in translates to about –60 dBFS to 0 dBFS. A
full scale (0 dBFS) sine wave, with Threshold set
at max (+20 dBv), will cause the Dyna-mite to just
start to limit or expand. The exact values depends on
the mode selected.
vCA Gain Coupling
(a.k.a. Auto Make-Up Gain)
In internal limit and DS-FM modes, the Dyna-mite en-
gages the VCA Gain Coupling which acts like an automatic
make-up gain.
