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 the initial test winding.
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 input tubes as well as the compression behavior. It gives a smoother sounding response but a harder knee.
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.
