The SPL TDx Transient Designer brings level-independent dynamics processing to the world of 500 Series.
The On/Bypass switch of the SPL TDx activates (On) or deactivates (Bypass) the module. This allows you to quickly switch between processed and unprocessed signal. The Sig LED (Sig) indicates whether an audio signal is present at the input which has a level higher than -20 dB.
Attack can be used to increase or attenuate the attack phase of a signal by up to 15 dB. Positive attack increases the amplitude of the attack phase. Negative attack attenuates the amplitude of the attack phase. With Sustain the decay phase of a signal can be increased or attenuated by up to 24 dB. Positive Sustain extends the decay. Negative Sustain shortens the decay.
The mix control allows continuously blending between processed (WET) and unprocessed (DRY) signals. With the output control the output gain can be attenuated in order to optimally drive following devices.
Differential Envelope Technology (DET) enables, through differential envelopes, level-independent processing of dynamic signal characteristics. Only two controls are needed to control the transient response.
