Details
Controls: Threshold, Attack, Release, Gain (output level), 3-way rotary switch (bypass/compression/HPF mode), high-pass filter (~100Hz)
I/O: Rear-panel balanced XLR line input and output; front-panel output level indicator; IEC mains
Notable use: Used by Dom Morley, Wes Maebe, Brian Moncarz and others, primarily on vocals, per manufacturer site
Notes: Single-channel all-tube Class-A PWM (Pulse Width Modulation) compressor, circuit derived from the D.W. Fearn VT-7 (flagged D.W. Fearn heritage). Gain reduction range 15dB max, THD <0.07% (site) / 0.04% at nominal (Sound on Sound), SNR >80dB. Four 6072A dual-triode tubes; Jensen input transformer, custom output transformer (Sound on Sound). Weight 5.6kg/12.5lbs, 2U rack (Sound on Sound review, not on manufacturer page). Price $4,500 consistent across Sweetwater/Reverb/Alto Music (2026); Sound on Sound (2022) cited ~$4,395/£4,395 basis. Note: this is the rack version; DNE below is the 500-series module derived from the same compression circuit.
