Bellari RP-533
# 23734
Heavily modified by Vince. 7 new switches, overdrive control, combo mic pre/comp/eq with many added features. Low noise high gain tube modification. 2 Band Bass/Treble. Front panel paid gain/phase switch. Tape saturation control. Smooth fast compression switch. High gain / bright switch. Power supply ground mod. Transformer EQ optical mod. This is the cats meow! Call for details 617-926-8020. Top flight cosmetic condition #8 with just a tiny bit of rack rash. Some additional information customers have asked about: This unit is 90% all tube, the op amps are for RMS, DC control, balanced out not audio! What I do is make the circuits have more head room less noise better tube character and more correct RMS detector tracking. As you may have noticed the output circuit clips badly and is nowhere close to semi-pro level. It's a wrongly done balanced line op amp stage. Also the compressor threshold and ratio controls are too sensitive, as such the unit can go into a strange and not very likable distortion if pushed. There is some good basic design circuits in this, but just not enough. My mods are not about installing fancy parts it's about improved circuit performance

Tube mic preamp/compressor/equalizer. AUDIO PRO MODIFIED: Tube Harmonic T. H. E. Bias control transformer in Vactrol EQ Mod. Highly recommended, Super noise spec machine! QC, Test All. #10 new in box
$ 568
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.

Behringer Composer MDX2100
# 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.

FMR Audio RNC1773
# 48385
"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.

Behringer MDX-1000 Autocom
# 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.

Back panel features: Balanced I/O, RCA I/O, Side Chain I/O. Unit has seen low hours of use and it shows. It has excellent calibration channel to channel and is more of a volume ranging compressor as it does some "make up" gain automatically when compressing. Completely cleaned and calibrated.
