Advanced Control Circuitry

Compressor features a gain-reduction element, positioned immediately after the input transformer. It is controlled by the sidechain amplifier, which also contain the two time control circuits one for fixed and one for variable Attack/Release. The two time-controllers can either be use separately or combined. This circuit contains semiconductor OP-amps for the entire control.

Versatile Features

The gain-reduction element is followed by a tube-based push-pull amplifier with variable gain up to 30 dB. A dedicated Bus selector with three positions (Off, Bus 1, Bus 2) is used whenever you want to link several compressors together. Input and output transformers have a static-screen between the primary and secondary wirings. Both Input and Output are balanced as well as fully floating.
