MindPrint-DTC TM
3.3 Release
The Release control determines how much time
should be allowed to pass, after the unit has
reduced a loud signal, before it is ready to again
raise a soft signal.
Operation:
RELEASE: The Release time can be set to
anywhere from 20 milliseconds to 2 full seconds.
3.4 Filter
The Low-Cut Sidechain Filter removes low
frequencies from the control path of the
compressor in order to prevent bass-heavy
signals from making the compressor overreact.
Operation:
FILTER: By pressing this button in you activate
frequency-dependent compression.
Triggering frequencies: 300 Hz and below
Slope: 6 dB per octave
3. 5 Link
Pressing in the LINK button will tie the left and
right channels together for control purposes.
The louder signal at any given moment willl
determine the degree of compression that will be
used on both channels. The compression and
release controls of the right channel are
deactivated, and settings can be made on the
left channel only, with the right channel acting
as a slave to the left. In processing a stereo
signal, this will avoid unwanted "wandering" of
the instruments across the stereo image.
Operation:
LINK: switches the Link function on.
HELPFUL HINT
A very fast Release setting (completely counter-
clockwise) tends to raise the level of reverb trails and
overly thicken the sound. Especially with low-
frequency sounds and low-level sounds, this setting
may result in some audible artifacts, i.e. distortion.
This is not a fault of the DTC™, but is the natural
result of making rapid changes in longer or softer
waveforms. In such a case as this you should set the
Release time a little longer or simply not compress
quite as strongly. With longer release times, more of
the character of the original signal is preserved.
Thanks to the AdaptiveResponse™ circuitry, using a
maximum setting here (full clockwise) ordinarily will
not cause problems.
AdaptiveResponse™
AdaptiveResponse™ is a circuit developed by
MindPrint that operates with several control times
which are mutually interdependent., and which uses
intelligent automatic circuitry to adjust the Attack
and Release times to avoid unwanted side effects.
The Adaptive circuitry changes the given Release time
so as to use a quicker control setting with shorter
signals, and a slower setting with longer signals.
A standard compressor will kick in, for example, when
signal peaks appear in material that is already fairly
dense, and you will hear pumping. Here an
additional controlling function kicks in which handles
fast transients independently of the basic setting.
INFO
Pumping can occur when bass-heavy signals affect
the sensors too strongly. For this reason the filter was
designed in such a way as to make the compressor
less sensitive to low frequencies, resulting in a type of
compression that corresponds much more closely to
the way the human ear actually works. Since we are
modeling a natural function of human hearing, this
filter circuitry improves practically every signal
thrown at it.
Since this filter is not in the signal path but is only
part of the sidechain control circuitry, it does not
directly affect the sound of the signal, but only the
way in which the compressor works.
HELPFUL HINT
You may also use the LINK switch for frequency-
dependent compression by feeding the right and left
channel of the DTC™ with the same mono signal (e.g.
from the Insert Send of channel 1 into the Insert
Return of channel 2), but using only one output.
Then you can use the equalizer of the second
channel to boost or cut those frequency bands that
will then be more strongly or mildly compressed.
By boosting the highs, for example, you create a
De-Esser function, i.e. vocal sibilance is reduced.
In general with this type of application you should be
careful to ensure that the level in the control channel
(the EQ channel) is somewhat higher than that in the
processed channel, since the louder channel is always
the one which will determine the degree and type
of compression.
