Dbx Digital, a pioneer in the audio processing industry, has been at the forefront of innovation for decades. Founded in 1971 by David E. Blackmer, the company's name "dbx" is derived from the term "decibels expanded," reflecting its initial focus on reducing noise and improving audio fidelity. With a rich history spanning over 50 years, Dbx Digital has evolved to become a leading manufacturer of professional audio equipment, including compressors, limiters, and noise reduction systems.
Early Innovations and Impact on the Music Industry

Technical Specifications and Applications
The dbx 160 compressor features a unique “over-easy” compression circuit, which provides a smooth, natural-sounding compression characteristic. With a threshold range of -40 dB to +20 dB, this compressor is suitable for a wide range of applications, from subtle dynamic control to extreme limiting. The dbx 160 has been used on countless recordings, including iconic albums by The Beatles, Pink Floyd, and Led Zeppelin. Its impact on the music industry can be seen in the work of legendary audio engineers, such as George Martin and Alan Parsons, who have relied on the dbx 160 to achieve their signature sounds.
