Behringer 369 Dual Channel Stereo Compressor Limiter Rack Processor

Behringer 369 is a two channel stereo compressor and limiter designed for mixing, mastering, and broadcast signal control. It enables dynamic range compression and peak limiting for audio engineers, supporting signal processing workflows in studio and live production environments. This makes it ideal for stereo bus compression, mastering chains, and broadcast processing where controlled dynamics are critical.

The processor operates as a discrete Class-A dynamics unit with transformer-balanced inputs and outputs. It integrates independent compressor and limiter sections per channel with selectable ratios, threshold controls, and adjustable recovery times.

In practical workflows, the unit can function as a stereo bus compressor, dual-mono dynamics processor, or mastering dynamics stage. Its switching and control architecture supports linking channels for stereo operation or running each channel independently.
