dbx is an American professional audio manufacturer founded in 1971 by David E. Blackmer, with the brand name derived from his initials. The company's early work centered on two foundational inventions: the Blackmer gain cell, a voltage-controlled amplifier (VCA) designed for professional audio, and the dbx RMS level detector. These circuits became the basis of the dbx 160 compressor, introduced in 1976, which helped define the sound of studio dynamics processing and remains a reference point for VCA-style compression.
The brand is also known for the dbx noise reduction system, a companding format used in analog tape recording that competed with Dolby NR, and for products such as the Model 700 digital audio processor. dbx was acquired by BSR in 1979 and, from 1979 through 1989, its name also appeared on consumer audio gear including speakers, CD players, and amplifiers. The brand is now part of Harman Professional Solutions.
Today, dbx focuses on professional signal processing for studio and live sound. Its catalog includes dynamics processors like the 266xs and 166xs compressor/gates, the 560A 500-series compressor, and the 160SL, along with graphic equalizers, loudspeaker management systems such as the DriveRack line, and feedback suppression processors. Many of its compressors feature the brand's OverEasy soft-knee compression and AutoDynamic attack and release controls.
dbx has 161 products cataloged on Equipboard, including Effects Processors, Preamps, and Channel Strips. Their gear is featured by 175 artists, with the strongest followings in Rock, Electronic, and Pop. Notable users include Kevin Parker, Mac DeMarco, and John Petrucci. dbx's catalog spans the full price spectrum — from entry-level options to high-end flagships.
