The DBX 117 Decilinear Compressor remains a legendary piece of vintage outboard gear, highly coveted by audio engineers for its unique ability to impart a smooth, musical character to recordings. Introduced in the 1970s, it functions as a "decilinear" processor, meaning it provides both compression and expansion capabilities by operating on a logarithmic scale that corresponds to human hearing. Known for its deceptively simple interface, the 117 features a single "compression" knob that controls both the threshold and the ratio simultaneously, making it an intuitive tool for taming transients or adding punch to drums, vocals, and bass. It's analog circuitry excels at "gluing" a mix together, offering a distinctively warm, vintage grit that continues to define the sound of many classic studio productions.
