Elevate your audio experience with the API 235L 200 Series Gate / Expander Module, a versatile tool designed to precisely manage noise without compromising the integrity of your sound. Whether you're in a studio, on stage, or broadcasting live, the 235L's exceptional speed and accuracy make it a must-have in any professional audio setup.

This module is engineered to handle a broad range of program levels, featuring a dynamic adjustment range from -45 to +25 dBu. Its ability to open remarkably fast ensures that your audio retains its full richness and nuance, even in the face of high background noise. The 1:2 Expander function is particularly adept at maintaining the subtleties of vocals and percussion, gently lifting the signal without losing those delicate under-threshold details.

Designed for flexibility, the 235L offers customizable settings including Threshold, Attack, and Release controls, allowing you to dial in the perfect configuration for your needs. For creative effects like the iconic "gated snare reverb," the Release function can be switched to Hold, providing even more control over your soundscape.

Built with API’s legendary 2510 and 2520 op-amps, this module guarantees reliability and long-lasting performance, making it a staple in any engineer's toolkit.
