Tube microphone preamp. Audio Pro Modified for tube harmonic enhancement circuit, high quality USA Sylvania 12AX7A tube, also has IN/OUT phase, second harmonic enhance Control. Six stage tube design for preamp, compression, and equalization. New stock fully QC'ed. With true tube "Gain Cell" compressor. Super spec unit.
Mint condition with box and packaging including users guide and warranty card. Compressor, Meequalizer, and dynamic Enhancer. Earlier version sales representative sample. Owners personal unit, used as a studio comparison model. #9+ condition
Very obvious gain ranging compressor, similar in design to Aphex Easy Rider and many other vintage designs. Warm sounding, old school design uses SSM2010 VCA. XLR and phone in/out, side chain connection. Excellent #9 condition, professionally cleaned and serviced.

Super quality design. Similar to DBX160XT except 2 channels with noise gate. Heavy duty design. Very sophisticated gain ranging design with very accurate calibrated panel controls. Full in/outs for side chain use and phone XLR. Channel calibration within 1 db over 70 db dynamic range!!! Modification to RMS Detector to lessen RMS detector leakage into audio and nicer max compression effect for bigger sound. Low use, all cleaned, minor scuff on top and face. Condition #9-
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.
2 Channel inputs, outputs with independent controls for gain, limiter, expander/gate and compressor. Low use, calibrated channel tracking +/- 1db over 80db range. 9/10 condition, Unit is in great condition, some scratches on top but faceplate is nearly flawless.
Modified to do greater compression and expansion range. For studio use or consumer. Has old style metal shielded modules similar to old DBX 160 series RCA in out. But unit will operate sem pro +14db levels now.
Gated compressor/limiter, gain riding/leveling circuit. 2 channels A+B, blue face panel w/dB meters, De-esser control. Norm/HVY. Modified / upgrade power supply caps and R. F. I protection . This unit has minor modification to allow use as non-balance line as well as standard balance line operation. Rack rush around mounting holes. Good condition low use unit, #9
