The Legacy of the "Stereo Bus Compressor" in a Compact Format
This module translates the much-loved musical signature found on countless albums into the API 500 format. It delivers the impact, cohesion, and the famous "glue" effect associated with the historic stereo bus compressor, now accessible in a more flexible modular chassis for modern studios.
Who Is It For and What Are Its Uses?
Ideal for mixers, producers, and creators working in hybrid studios, this compressor offers transparent compression for a glued final mix, yet enough character to tighten drums, an instrument bus, or a full track in light mastering. Its precise dynamic control speeds up decision-making during sessions.
Key Features for a Smooth Workflow
Musical and Controlled Compression
The 6 ratios, from 1.5:1 to 20:1, cover subtle "glue" to firm hold. The 5 release settings plus Auto mode allow you to match the groove of the track or ensure consistent playback when the program material varies.
Intelligent Sidechain
The high-pass filter in the sidechain prevents excessive compression triggered by low frequencies. The result: a clean and present low end, breathing mids, and a mix that stays solid even at high RMS levels.
500 Format, Dual Slot
Occupying two slots ensures easy integration into your lunchbox while allowing the electronics to operate comfortably in stereo. You benefit from consistent processing ready for critical mix bus tasks.
