• Classic VCA compressor/limiter with fast response
• Perfect for drums, vocals, and transient material
• Transparent compression or aggressive peak control
• Wide range of ratio and release settings
• Recreation of an iconic 1980s dynamics module

Designed for both control and character, the X903 offers lightning-fast response times ideal for transient-heavy material such as drums, vocals, and guitars. Its VCA-based topology ensures tight, consistent compression with minimal coloration while retaining the punch and definition of the source.

Additional ratio and release settings allow for everything from subtle smoothing to aggressive peak limiting, making X903 an indispensable dynamics tool for modern productions.

The original hardware that inspired the X903 was a rack-mounted version of a popular console module, celebrated for its reliability and flexible dynamic control. It shaped the sound of countless hit records through the 1980s and beyond. Antelope Audio’s recreation brings that same performance accuracy to the digital realm, preserving its fast and musical behavior.
