Quad compressor/limiter. 4 chan (2 linkable in pairs) comp/limiter. Lo-pass filter, sweepable 20hz-20khz. Compand, threshold, ratio, gain, attack, release, and limit knobs. Optical, link 1/2 (3/4), auto and bypass switches. 10-led metering of gain reduction. XLR and 1/4" in/out with side chain input. Nice performance, good build quality! #9 condition with some minor rack rash. With manual.
Eight channel analog controlled dynamic processor, full function compressor and noise gate. Excellent #9 condition, one knob missing to be replaced with nonoriginal. Professionally cleaned, serviced, and tested.
Stereo/2-chan compressor/limiter/noise gate. High spec spectral noise gates. Balanced XLR in/out, balanced 1/4" in/out with side chain. All controls and switches cleaned, all functions check ok! With Manual. #9 condition, minor rack rash.
Stereo tube compressor. Super spec noise and calibration unit with minor AP-modifications of critical tube selection and internal calibration to allow "warmth control" to create in phase or out of phase perfect second harmonics of .2 to 1%. (Warmth meter will now read lower than original.) Noise mod in power supply. Excellent condition.
Unit has super spec controls. Two channels of expander/gate and compressor/limiter. Two 12AX7 tubes to add harmonic character. Both channels track within 0.5 db of each other! Up to 60db range of compression. Modified for more pleasing 2nd order harmonic enhanced sound. Demo unit, with box, packing and manual. Please call for details.
Limiter Compressor, 2 ch. Slave switch/external detector, RF earthing cap, minor upgrades, excellent condition. #9 Unit with Valley People VCA Modules---NPW Probably SOLD Similar unit available
FYI, Around the database you will often see us describe the condition of units on a scale of 1-10. #10 would mean the product is new from one of our suppliers, such as Behringer, Audio Technica, etc. #9 means the product is in perfect condition but is used, #8 implies there are some minor cosmetic scratches but unit is mechanically perfect, and so on and so forth.
Limiter, Ducker 2 channel, true balanced IC socketed op amp design. Uses Valley People VCA modules. Calibrated. Low use unit from Shop owners studio, No Rack Rash. #9 condition
Demo, compressor/limiter/expander/gate, 2 channel, XLR and 1/4" ins and outs, original like new, better built, better performance, excellent high accuracy compressor, channel matching for tracking is superb
Units vary in retail cost due to condition. Real nice, modified, low use units get more money. The simple fact is this era design compressor is the same as the DBX XT !! But I modify many designs with more R.F.I. suppression and less R.M.S. detector noise getting into the audio V.C.A. (check the internet if not familiar with the abbreviations) Simply put, mods make a slightly cleaner, better accuracy and control of compression of the audio signals. This is done to accommodate today's higher quality signals from microphones and the intense dynamics in modern music.

Compressor and noise gate pair mounted together in rack. Very good #8+ condition with many tiny minor scratches on ears and face.
Dual compressor, expander gate w/ compressor limit threshold output level, uses Valley People VCA modules, phone in and out, process loop in and out, new control installed.
Composer Compressor, Has upgrade RMS detector mods. Super Low noise P.S. mods. Channel matching/compression calibration. Call for Details.
2 channel Compressor, one of the best. Modified P.S ground and shields on VCA, with Rack ears. Super high spec Calibration. Low use, all cleaned and calibrated. #9 condition +- .5db over 80 db range compression
All Remotes are now 25% off or Free Shipping!!! (Reel to Reel remotes excluded).
500 series format plug in. Top quality vactrol design. 10 (new) condition.
"Really Nice Compressor," with controls for threshold, ratio, attack, release, and gain. Bypass and "super nice" switches. The RMS digital detector circuit in this unit causes chattering and gulging noise in the audio, especially at low threshold settings. We modified the circuit to improve the audio quality and give the threshold control better range. Unit is now more accurate, releases fast and consistently, and compressed voice of instruments is cleaner and more detailed with subtle dynamics. Like new condition, with power supply and manual.
Excellent mint condition as new, with original box, packing, and manual. Great multifunction 2 channel gate, excellent spec.
Vacuum Tube Processor, 2 channels, Gate/Expander, Comp/Limiter and Warmth controls, Ultra-low noise, QC check ok: all switches match with 1db on both channels
This is the older, more well built version compressor, actually a DBX 166 or 160x design (licensed to Behringer), with all controls and switches done better. I also correct a design flaw in these units (there is some sonic distortion and crosstalk of the controlling voltages into the VCA) and improve the power supply decoupling. Vince personally uses one of these units in his synth studio for final mix.
2 Channel Vactrol/ tube leveling amp, 2 TRS inputs/outputs, 2 XLR inputs/outputs, threshold, ratio, output controls, complete service, power supply mod 35V caps #9+ condition
