IGS Audio Zen Compressor
The ZEN is unique. The construction is based on the legendary compressors used in Abbey Road Studios. It’s the musical canon of art used by The Beatles. The ZEN Compressor audio circuit is based on 14 bi-polar transistors in each channel. The compression is achieved by 8 hand-matched Zener diodes biased by a perfect feedback circuit.
