Alesis 3630 Compressor

Great compression makes a huge difference in your music; it can turn a mediocre demo into a processional-quality production. The 3630 Compressor is designed as a high-quality, versatile compression unit which can be used live or in the studio with consistent results. The 3630 is a dual-channel compressor that offers Ratio, Threshold, Attack, and Decay controls to handle the toughtest signals. You can choose between RMS and Peak compression styles, plus Hard and Soft Knee dynamic curves for every application from subtle gain control to in-your face punch. Plus, 2 fully independent gates give you even more control when dealing with difficult signals. Other advanced dynamics processing features such as precise signal metering, a sidechain for keying or ducking effects, and stereo linkable operation make the 3630 the most powerful compressor in its class.
