Dynafex DX-2 Noise Reduction System

CRL Dynafex DX-2 2-channel analog noise reduction system. This is a highly regarded, professional-grade 1U rackmount unit from the late 1980s/early 1990s, built by Circuit Research Labs. Unlike Dolby or dbx systems, the Dynafex DX-2 is single-ended. It does not require encoded source material. It works in real-time on any pre-recorded audio, live feed, or tape transfer to remove up to 30 dB of background hiss, hum, and line noise without dulling your high end. Perfect for analog/vintage studio setups, vinyl/tape digital archiving, or adding analog warmth and dynamic filtering to your hybrid DAW workflow.Features & Specifications
