S-Type 500 VU

Stereo VCA Compressor

The S-Type 500 VU is a stereo bus compressor inspired by the iconic dynamics of legendary British large-format consoles. Designed around a modern THAT VCA and ultra-fast, balanced op-amp signal paths, it delivers transparent compression with exceptionally low noise. With RMS detection, high-headroom circuitry, and a built-in sidechain high-pass filter, the S-Type 500 allows mixes to breathe while maintaining punch and cohesion. From subtle glue on the stereo bus to aggressive parallel compression, it provides precise control and musical results across a wide range of professional applications.

Classic Console Compression, Modern Precision
The S-Type 500 VU faithfully captures the character of classic British bus compression while employing modern components for consistency, reliability, and clarity. The use of a THAT integrated circuit replaces the now-unavailable DBX design, ensuring transparent dynamics control with minimal noise.

Stereo Control with Creative Flexibility
Both channels are summed to control the VCA stages simultaneously, guaranteeing stable stereo imaging. A large gain-reduction meter provides clear visual feedback, while the MIX control enables parallel compression, making it easy to blend aggressive dynamics with the original signal for impact and depth.

Advanced Sidechain Capabilities
An onboard sidechain high-pass filter allows low frequencies to pass uncompressed, preventing unwanted pumping and preserving low-end energy. The external sidechain input further expands creative routing possibilities, making the S-Type 500 equally at home in mixing, mastering, and sound-design workflows.

The Go-To Stereo Bus Tool
From gentle cohesion to assertive punch, the S-Type 500 delivers the familiar “glue” heard on countless records. It is designed to sound musical across all settings, making it a dependable and expressive compressor for demanding professional environments.
