The Drawmer DL221 is a dual-channel analog VCA compressor/limiter that can operate in dual mono or stereo-linked modes. Each channel features a compressor with adjustable threshold, ratio, attack, and release controls, along with an ultra-fast peak limiter to prevent overloads. It is known for its low distortion, wide dynamic range, and the ability to use an external sidechain, making it a versatile tool for dynamic control in both studio and live sound applications.
