The Aphex Model 661 is a totally new type of compressor incorporating vacuum tube technology with the latest innovations in audio compression.
Use the Model 661 to control dynamics for mixdowns, protect your sound system's loudspeakers from transients and distortion or shape the sound of individual instruments and vocals.
This is most useful when using the 661 (two in stereo link mode) to process a stereo mix-down of bass predominant material.
