J33™ Specifications

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.
