3BX-DS

About the 3BX-DS

The dbx 3BX-DS is a sophisticated dynamic range controller that combines four processors in one: a dynamic-range expander, dynamic-range compressor, impact recoverer, and ambience controller. It divides the audio spectrum into three separate frequency bands (bass, midrange, treble) and processes each band individually using true RMS detectors and voltage-controlled amplifiers. This multi-band approach allows precise dynamic range expansion and compression without unwanted artifacts, preserving the integrity of complex musical material. The impact recovery feature is unique in that it provides three separate meters for impact restoration across the three frequency bands, unlike other models which have only one meter. The unit also includes controls for compression, expansion, and impact recovery, with LED meters indicating gain changes. It is highly regarded for delivering high sound quality and is favored by audiophiles seeking detailed dynamic control.
