The ART SCL2 Stereo Compressor is a highly sophisticated and flexible dual-channel dynamic compressor/limiter, expander/gate designed for easy operation. The unit can be adjusted to provide any level of compression, from subtle and fine to hard and heavy limiting. Noise reduction is provided by a solid fast gate or a delicate expander. The attack and release functions allow the user to set the overall operating range and then automatically adapt to the audio being processed. A full automatic mode is also available.
