    Dual-Band De-Esser 500 Series module

    Back in the 1990‘s, we developed an alternative way to process signals based on phase cancellation in order to reduce sibilance.

    Unlike traditional compression methods, this procedure is much more unobtrusive and simplifies control to one single parameter. SPL‘s De-Esser quickly became a standard reference among recording studios, broadcast stations and live sound engineers.

    The Dual-Band De-Esser expands on this concept by making use of two frequency bands that can be used independently or jointly. Two de-esser stages increase processing effectiveness without introducing audible artifacts. Focused processing with high and low bands makes it possible to process sibilant sounds with great precision. Furthermore, input signals are automatically adjusted so the processing is uniform, regardless of the distance between source and microphone. The Male/Female modes adapt processing in the lower band to male or female voices.

    Now, the Dual Band De-Esser DeS is also available in 500 Series format
