The Transient Designer with the revolutionary Differential Envelope Technology (DET)

Level independent dynamic shaping: for the first time it is possible to set attack and sustain in a very simple way.

Description

The Transient Designer revolutionizes dynamics editing. For the first time, the envelopes of audio signals can be edited independently of the level. Transients can be accelerated or slowed down, decay times can be lengthened or shortened. The Transient Designer offers unique processing options for signal dynamics that cannot be achieved with conventional compressors.
You will not find parameters such as threshold, ratio and gain , nor time constant parameters. The user is only provided with the parameters that are really important: With just two controls per channel (attack and sustain), transient response can be boosted or reduced by up to 15 dB and decay by up to 24 dB become. All time constants are musically automated and adaptively optimize according to the characteristics of the input signal.

The Transient Designer has envelope tracers that align the work processes with the natural signal curve. This way, optimal results are achieved for every moment in the music. Setting a threshold value is unnecessary due to the level-independent nature of the processing.
The Transient Designer works on the basis of THAT 2181 VCAs, which are particularly transparent, sound-neutral and low in distortion. Even at high processing intensities, no treble attenuation effects or bass reduction occur. For stereo operation, the link function is activated, which allows two of the four channels to be linked together. Both channels receive the same control voltage to ensure a coherent stereo image. The controls of the first (or third) channel including the active circuit then control the second (or fourth) channel. Each channel equipped with a relay hard bypass circuit. The signal LEDs are used to quickly control the signal flow, which is particularly important when the four channels are plugged into a patchbay.

The controls

Active

The active switching functions, designated by the number of the respective channel (1 to 4), switch the channels on or off individually. The status LEDs indicate that the respective channel is activated. With Active, relay hard bypass circuits are operated, which implement a direct "hard-wired" redirection of the inputs to the outputs. Even in the event of a power error on the primary or secondary side of the power supply, the device is switched to hard bypass via a relay. If the Transient Designer is operated in link mode (see point 5), the active switches on channels one and three are also responsible for channels two and four. The status LEDs in the second and fourth channels also light up when the first or third channel is activated.

Signal LED

The signal LED indicates whether an audio signal is present at the input and its level exceeds -40 dB. The LED display serves as an aid to quickly identify in complex studio cabling whether a signal is actually arriving at the Transient Designer.

Attack control

The attack control can be used to increase or decrease the attack phase of a signal by up to 15 dB. To better understand how the attack control works, please read the explanations in the Tech Talk. Two envelope generators work in the attack control network. One follows the original envelope and adapts to its curve as optimally as possible. The second generator produces an envelope with a weaker attack

A difference is formed from the two envelopes, which serves as a control voltage for the VCA (THAT 2181). The course of the control voltage is now completely adapted to the timing of the original signal. If a positive attack value is set, the amplitude of the transient response increases. Negative attack values ​​lead to a weakening of the amplitude of the transient response.

Sustain control

The sustain control can be used to increase or decrease the decay phase of a signal by up to 24 dB. To better understand how the Sustain control works, please read the explanations in the Tech Talk. Two envelope generators also work in the sustain control network. In turn, an envelope tracker tracks the original envelope and adapts optimally to the curve shape of the decay phase. The second generator produces an envelope with a longer lasting sustain.

A difference is formed from the two envelopes, which serves as a control voltage for the VCA (THAT 2181). The course of the control voltage is in turn adapted to the timing of the original signal. If positive sustain values ​​are set, the amplitude of the decay process increases. Negative sustain values ​​result in a weakening of the decay amplitude.

Link function

For stereo operation, the link function is activated so that both channels receive the same control voltage to ensure a coherent stereo image. The controls of the first and third channels, including the active circuit, then control channels 2 and 4. The active LEDs of channels two and four are also controlled by the first and third channels.
