Empirical EL-DS Labs DerrEsser 500 Series

The DerrEsser is a versatile dynamic filtering tool designed in the compact 500 series module format. At its core, the DerrEsser functions as an effective, level-insensitive de-esser, ideal for controlling excessive high frequencies or harsh treble in vocals and other audio sources.

Core Functionality: De-Essing
In its primary "DS" mode, the DerrEsser dynamically reduces high-frequency gain on spiky or overly bright material. By utilizing a crossover technique to split the audio signal into high- and low-frequency bands, the device employs a Voltage Controlled Amplifier (VCA) to smoothly attenuate harsh high frequencies. This process is executed with remarkable musicality, ensuring natural and transparent results.

Beyond De-Essing
What sets the DerrEsser apart is its multi-functional design, which extends its capabilities beyond traditional de-essing. Its flexible circuitry allows it to be used for various applications, offering creative possibilities for dynamic tone shaping and control.

The DerrEsser combines precision, versatility, and a musical approach, making it an indispensable tool for any audio professional.
