The SPL TDx 500 Series Transient Designer Module is installed in a single slot of the 500-series rack module and is used to amplify or attenuate attacks and prolong or shorten the sustain. It features the Differential Envelope Technology (DET) that allows level-independent dynamic processing of signal paths by calculating differences in generated envelopes. These envelopes track the curve of the original signal to provide optimal results. Therefore, only two controls per channel are required to allow you to completely reshape the attack and sustain characteristics of a sound.

Thanks to the MIX (parallel mix) feature, you can continuously blend between the processed and unprocessed signal. The transient designer is suitable for use in professional recording, project or home studios, and in sound-reinforcement applications. Applied to single instruments or loops, it allows you to create new sounds and/or effects.
