David Blackmer, who is considered to be the father of the modern VCA, had an incurable quest of using decibel expansion to replace the peaks lost to the limited dynamic range of magnetic tape. This quest in turn produced the VCA and RMS detector that have in turn, changed the world of audio, yielding the dbx® noise reduction system, and dbx® compressors. In 1971, Mr. Blackmer founded dbx Professional Products which has collectively produced more than 37 patents that continue to forge and reshape the technology in live, install and tour professional audio markets today. Dbx Professional continue to design and build the precision and hyper-accurate graphic EQs, compressors, crossovers, mic preamps, digital processors and control systems for highly-scrutinizing audio society.
