The Transient Designer provides a revolutionary concept for level-independent
dynamic processing. In this it differs in principle from common compressors that
are based upon processing signals of a specific level. Working with the Transient
Designer is very simple: Attacks can be amplified or attenuated and sustain may
be prolonged or shortened. However, the possibilities for studio and live applica-
tion are seemingly endless.
Technical foundation is SPL‘s Differential Envelope Technology (DET) which allows level-inde-
pendent dynamic processing by calculating differences in generated envelopes. These enve-
lopes are always tracking the curve of the original signal to provide optimal results in every
moment of the music.
Thanks to the level-independent processing DET the setting of a threshold is needless. Other
common controls of dynamic processing, such as ratio or parameters for time-constants are
automated and optimized adaptively in a musical manner according to the characteristics of
the input signal.
So only two controls per channel are required to allow the user to completely reshape the
attack and sustain characteristics of a sound: attack can be amplified or attenuated by up to
15dB while sustain can be amplified or attenuated by up to 24 dB.
Thus, in a very obvious and simple way, the Transient Designer opens a whole new dimension
in dynamic processing with entirely new, stunning and vast possibilities for dynamic manip-
ulation and processing that cannot even be duplicated with several daisy-chained, conven-
tional compressors or other dynamics devices.
A new feature of the Transient Designer module is the output gain control that enables you
to compensate changes in the level of the processed signal. This ensures a simple and safe
adjustment of levels for any following device – especially A/D converters.
The Transient Designer uses the excellently specified THAT 2181-VCAs, which are particu-
larly natural and transparent sounding and renowned for minimal distortion values. The 2181
processes highest amplitudes without damping of high frequencies or reducing bass.
The module is equipped with a relay hard bypass to ensure the switching audio signals
directly from input to outputs in the case of a power failure. Signal flow is always maintained.
On
With the ON button you can turn the device on or off. The ON button is illuminated when the
device is active.
Relay hard bypass circuits ensure signals to be directly switched from input to output in the
case power failures – this “Power Fail Safety“ feature guarantees signal flow in any situation.
If you operate a Transient Designer module in LINK-Mode, the ON button of the master module
(left) controls both modules. The LINK and ON buttons of the Transient Designer module that
is currently in LINK mode will thus be illuminated as well—although they have not been acti-
vated.
Attack
With the ATTACK control you can amplify or attenuate the attack of a signal by up to 15 dB.
The ATTACK control circuitry uses two envelope generators. One follows the shape of the
original curve and adapts perfectly to the dynamic gradient. The second envelope generator
produces an envelope with a slower attack. From the difference of both envelopes the VCA
control voltage is derived. Positive ATTACK values emphasize attack events, negative ATTACK
values smooth out the attack envelopes of sound events.
For an extensive description and explanation of the possible applications of the ATTACK
control please refer to “Applications” on pp. 42-43.
