Radial J33 Phono Preamp Active Turntable Preamp & DI Box
Active Turntable Preamp & DI Box
The J33™ combines a high quality turntable (phono) preamp with a DI box, providing consumer line-level outputs in addition to balanced mic-level outputs that allow you to connect a record player to pro audio equipment such as mixing consoles and recording interfaces.
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 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.
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.
