DBX 3BX Version 1
# 27721
3 band (low/mid/hi) compressor/expander in nice condition with wood sides. Original version with individual board modules for VCA! Modified with 3 band controls and ground mods (no input gain mods). Low noise spec. This is the early version unit preferred by audiophiles.

In addition to proper cleaning and calibration we replace any off spec parts (which will happen naturally on a 30 year old device). The modification I do adds 3 newly installed front panel controls which allow for full adjustment of expansion vs. Compression of each low, middle, and high band. Although the ins/outs are RCA, the 3BX has no trouble handling +14 dbm. This device is probably the only 3 band expander/compressor available on the market. On a mix, one could expand the highs to zip up the clarity and reduce noise, while compressing the bass end to add thickness. Adjustment controls for dynamic range, threshold also increase the versatility

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.
