The Symetrix 422 Stereo AGC/Leveler is a professional analog automatic gain control processor designed to maintain consistent audio levels while preserving natural dynamics and clarity. Unlike conventional compressors that primarily reduce loud signals, the 422 combines downward compression with upward leveling, gently reducing louder passages and increasing quieter signals to bring the overall program material toward a user-defined target level. This makes it well suited for broadcast, recording studios, tape duplication, and installed sound systems where consistent, intelligible audio is essential.
Featuring adjustable detector threshold, compression ratio, and target level controls, the 422 provides flexible management of fluctuating audio sources. An integrated peak limiter helps prevent excessive output levels, while dedicated input and output meters provide clear visual monitoring. With stereo operation, balanced and unbalanced connectivity, remote bypass capability, and straightforward front-panel controls, the Symetrix 422 offers practical, transparent level management for professional audio applications.
