Empirical Labs EL500 API 500 Series Compatible Rack /DerrEsser EL-DS x2

Thank you for viewing this listing.

This is a complete Empirical Labs EL500 + DerrEsser EL-DS ×2 500 Series de-esser system.

The Empirical Labs DerrEsser EL-DS is a high-quality 500 Series de-esser designed to control harsh sibilance (such as excessive “S” and “T” sounds) while preserving vocal clarity, presence, and natural character.

Rather than simply cutting high frequencies, the DerrEsser EL-DS smoothly reduces unwanted sibilance while maintaining the energy and definition of the original source. It is ideal for vocal recording, mixing, and professional audio production, especially for users who want the immediacy, response, and sonic character of dedicated hardware processing rather than software plug-ins.

The included Empirical Labs EL500 rack chassis provides power and housing for API 500 Series compatible modules, allowing you to build a flexible and efficient outboard processing setup. With two DerrEsser EL-DS modules installed, this system is suitable for stereo processing, dual-channel operation, and professional vocal processing workflows.
