Bison 500

Parallel Mixer Width MidSide Processing

BISON 500 is a compact Mid/Side and parallel processing tool designed to transform any dual-mono compressor setup into a powerful stereo imaging processor. Built for the 500-series format, it allows engineers to route their favorite mono or dual-mono compressors into a Mid/Side matrix with an integrated dry/wet control. With just one switch and one knob, BISON 500 delivers enhanced stereo width, punch, and depth while preserving clarity. Simple, flexible, and intuitive, it adds advanced processing capabilities to existing compressors without altering their original character.

Mid/Side Processing Made Effortless
BISON 500 enables any pair of mono compressors to operate in Mid/Side mode. With a single switch, the left channel controls the Mid information, while the right channel processes the Side content. This allows precise control over stereo width, center focus, and spatial balance without complex routing.

Bring Your Own Compressors
Two stereo jack send and return connectors on the front panel make it easy to integrate external compressors directly into the Mid/Side matrix. Engineers can pair and experiment with different compressor types to shape stereo dynamics creatively.

Parallel Compression Control
The onboard dry/wet knob introduces effortless parallel processing. This makes it possible to add impact, density, and energy to a mix while retaining the natural dynamics of the unprocessed signal.

Minimal Controls, Maximum Impact
Designed for speed and clarity, BISON 500 uses a one-switch, one-knob interface that encourages experimentation without distraction, making it an ideal utility module for mixing, mastering, and creative sound design.
