dbx 33
Nothing specific is documented about the dbx 33. The archive's source material for this page is empty. There are no production dates, no price, no specifications and no design notes. No period review, service manual or equipment-directory entry for this model has been located. A contemporary dbx advertisement in Recording Engineer (February 1979, p.8) described its 208 noise reduction system as providing 30 dB of noise reduction and 10 dB of headroom improvement.
The closest the surviving period record comes is a High Fidelity equipment report (July 1982, p.30). It measured a tape machine's record/play response with dbx noise reduction engaged and got +6¼, -3 dB from 20 Hz to 20.4 kHz at 3¾ ips. The report names no specific dbx model, and nothing in it can be tied to the 33. Given the number's place in dbx's catalog, the 33 might have been an early, obscure or short-lived entry in the company's professional audio line. That is speculation, not documentation.
If the 33 existed as a distinct product, its record has been lost. The Archive would welcome a correction, a scan, or any documentation from an owner.
