A DI box for your turntables
The J33 provides the ability to connect turntables to pro audio equipment such as a recording interfaces and mixers, allowing you to easily integrate your vinyl collection with studio gear for playback or recording. Balanced XLR mic-level outputs are available for connection to a mic preamplifier for archiving or sampling in the studio, and -10dB consumer line-level outputs are also provided to connect to home stereo equipment. The J33 can also be used in a live performance environment, offering an improved interface for DJs to connect to the PA system.
The Radial J33 is a combination stereo phono preamp and direct box designed for dynamic cartridges. Careful attention has been paid to delivering a smooth sounding RIAA transfer curve while keeping the noise down to the absolute minimum for the noise-prone world of 33 RPM long-play records. Both unbalanced consumer line-level and balanced mic level outputs are supported.
