The CN-220 features an impressive + 24 dBu (max) input/output level operation and extremely low output noise. As an additional feature, the unit includes a band compressor mode with adjustable frequency to achieve a wide variety of effects (de-essing, vocal stopping, drum levelling, etc...). Electric bass guitar sounds, for example, become more natural as the harmonic contents are unaltered when "Slap Bass" playing.

Due to these complete features and excellent technical specifications the ALTAIR CN-220 has become a classic in professional audio, going a step further in dynamic processing.
