SPL Transient Designer RackPack Module

The SPL Transient Designer RackPack Module 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 application are seemingly endless.

Technical foundation is in SPL's Differential Envelope Technology (DET) which allows level-independent dynamic processing by calculating differences in generated envelopes. These envelopes 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. 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.

A new feature of the Transient Designer module for the RackPack series 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.
