The Dizengoff D864 Varimu Compressor is based on the classic Federal AM864 vari-mu compressor.   We chose to base the D864 transformers on the much loved Peerless-Altec designs of the 1960’s.  These are very highly regarded for their signal quality to this day, and used examples fetch a premium.  We chose nickel-50 core material for good signal fidelity.   For feature set, we have added some extras not found in the original build.  For example: variable attack and release, as well as ratio, threshold, and input trim controls.  Additionally, we included switchable bypass, link, and two unique features — Growl and Glow.   Growl is a sort of parallel germanium compression that can be switched in and out of circuit.  It adds a nice, trashy edge to the sound.   Glow shifts the behavior of the output stage.  It gives a more mid-forward response by shifting the way the output transformer saturates.  This makes it a great tool for bringing out a vocal or snare crack within a mix.   For the enclosure, we have designed a nice, 2U high all aluminum rack-mount case.  Metering is provided by a giant 2.55″ round A-scale VU meter.  Knobs are Chicago Daka Ware, of course.
