Transient Designer
4
The new TRANSIENT DESIGNER provides a revolutionary concept for
dynamic processing rendering controls such as Threshold, Ratio
and Gain superfluous. The T
RANSIENT DESIGNER's automation is
highly developed, so that while the processing going on inside
the box may be very complex, the user has to deal with just a few
intuitive controls. SPL's Differential Envelope Technology® is the
first solution for level-independent processing of envelopes allo-
wing transients to be accelerated or slowed down and sustain
prolonged or shortened. The degree of dynamic processing
required to do this couldn't be duplicated even using a chain of
several conventional compressors, yet 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 24dB, enabling
weak drum sounds to be made much more percussive and
powerful, or for over-percussive transients to be softened.All the
necessary time-constants (Attack, Decay and Release) are auto-
mated and optimised adaptively in a musical manner according
to the characteristics of the input signal. This results in natural
sounding signal processing and fast operation.
The T
RANSIENT DESIGNER uses envelope followers to track the
curve of the natural signal so that optimum results are guaran-
teed regardless of the input signal's dynamics. Because of the
level-independent processing inherent in Differential Envelope
Technology®, manual threshold adjustments are not required. In
order to maintain the cleanest possible signal path, the T
RANSIENT
DESIGNER uses the excellently specified THAT 2181-VCAs,which are
especially natural sounding, transparent and create minimal
distortion. High amplitudes are processed without damping of
high frequencies or reducing bass.
For stereo operation the LINK function connects channel pairs
(1,2 and/or 3,4) such that both channels are controlled by the
same side-chain voltage so as to maintain a coherent and stable
stereo image. When operating in LINK-mode, the control
elements of the first (or third) channel, including the ACTIVE
switch, control the second (or fourth) channel, too. Each channel
is equipped with a relay hard bypass circuit to ensure a minimum
signal path when the process is bypassed.
The Signal-LEDs provide a simple and positive means to quickly
monitor the signal flow,which is particularly important if the four
channels are connected to a patchbay.
The T
RANSIENT DESIGNER is a
revolutionary Dynamic
Processor based on level-
independent sound proces-
sing that makes it possible to
radically change the attack
and sustain characteristics of
any musical sound in a crea-
tive way.
Transients can be accelerated
or slowed down and sustain
may be prolonged or shor-
tened.
This is made possible by the
use of adaptively optimised
time-constant parameters.
SPL's Differential Envelope
Technology® for level-inde-
pendent processing.
The latest VCA-technology
preserves audio transparency
and minimises distortion.
There are four independent
channels of signal processing
in the T
RANSIENT DESIGNER,
though channels may also be
linked for stereo operation.
The unit features a relay hard
bypass and Signal-LEDs to
simplify metering.
