Behringer MDX-1000 Autocom

Audio Proz Inv #: 17203

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.

Behringer Composer MDX2100

Audio Proz Inv #: 23554

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.

ART PRO VLA II

Audio Proz Inv #: 58509

SN 1739 rev 4 modification. With PS MOD version 4 transformer. With deep bass enhancement, tunes transformer installed in vactrol. Voiced compressor to lessen a "crowded" mix in spatial midrange imaging. Transformer and enhancement now comes into mix when 2 LED's are lit on compressor. Super calibration, low noise channel spec matches + .5db over 58 db range. 9+ condition, new. Since people keep asking, I use an equalized transformer with capacitors and resistors �tuning� the transformer voice midrange slightly down is installed into the Vactrol circuit. This circuit now allows more bass depth and impulse response, as well as insures that high frequency and presence will not be compromised excessively. Also a little 2nd and 3rd harmonic is imparted on the audio to give a slightly thicker sound to the low midrange and up, somewhat like a tape recording or vintage tube/ transformer pre-amp. Except now everything is cleaner, less noise and stays calibrated same way every day every hour, you can lightly or heavily run the compressor for dramatic effects.. I've sent out this design to quite a few personal studios and the unit is some what tweaked for Rock and Roll or modern multi-instrument acoustic music. Some may have felt its most effective use is on tracking vocals.. Its really about combinations of mics and other matters when operating together.
