Product Overview

The J33 from Radial is designed specifically for use with turntables and is a combination RIAA turntable preamp and active direct box. This allows vinyl albums (LP's) to be connected directly to a microphone preamp in a mixing console. The unit is ideally suited for archiving, sampling, scratch performances and DJ mixing when the highest possible sound quality is required.
