Alesis 3630 Signal Compressor Dual Channel Compressor Limiter with Gate.
Since its introduction, the 3630 Compressor™ has become the most popular dynamics processor ever made. The reason is easy to understand: it provides two independent full-featured compressor/ limiters in one rack space while offering excellent sonic quality for any application from studio recording to live sound or broadcast. The 3630 offers Ratio, Threshold, Attack and Decay controls to customize its compression response for even the toughest signals. You can also 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. As an independent dual-channel compressor, the 3630 offers separate controls for two different source signals. Plus, two fully independent gates with threshold and rate controls allow you to easily and efficiently stifle unwanted ambient noise. 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.
Great compression makes a huge difference in your music; it can turn a mediocre demo into a professional 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.
