API Select SR22 Dual Channel Compressor – 2U Rackmount
The API Select SR22 is a premium-grade dual channel analog compressor housed in a rugged 2U rackmount enclosure. Designed around API’s patented and award-winning compression circuitry, the SR22 offers smooth, musical dynamic control with the signature warmth and precision that API is known for. Whether you’re tracking, mixing, or mastering, the SR22 is built to deliver uncompromising analog performance.
Each channel features API’s proprietary THRUST® circuit, a unique design that protects high-frequency content during heavy compression, preserving detail and clarity while allowing punchy and aggressive control over dynamics. With variable Threshold, Ratio, and Make-up Gain controls, the SR22 offers full flexibility for dialing in the perfect amount of compression for any source.
The front panel includes classic analog VU meters with switchable monitoring between output level and gain reduction, along with peak threshold LED indicators for real-time visual feedback. A switchable knee setting lets you toggle between smooth, transparent soft knee compression and more immediate, aggressive hard knee behavior.
For stereo applications, the SR22 includes a stereo link function with true RMS power summing, ensuring phase-accurate and cohesive stereo imaging. Balanced XLR and 1/4” TRS inputs and outputs provide versatile connectivity for integration into any studio setup, and the unit features an internal power supply for reliable operation.
