The Radial J33 is a combination phono preamplifier and purpose-built stereo direct box made to handle the rigors of the professional recording studio and the abusive environment of live touring. But don't let the tough exterior fool you… the J33's sonic performance will easily surpass many audiophile preamps costing much more.

Designed specifically for dynamic cartridges, the J33 begins with a low-noise front end. Inputs are standard RCA with the required turntable ground lug. A precise RIAA low-pass filter is tailored to produce a smooth, warm response. The signal is then buffered to provide the audio system with a standard -10dB signal with a choice of RCA connectors for compatibility with home HiFi entertainment systems, a 3.5mm (1/8") output to feed a laptop or iPod, or a stereo TRS ¼" jack for an audio recorder. A second set of direct box XLR outputs delivers a mic-level signal to feed a concert snake, mic splitter, and mixing desk preamp inputs. A rumble filter is also available for high sound pressure environments to reduce bothersome resonant feedback.

As with all Radial DIs, the J33 features a 14-gauge steel enclosure with a unique bookend design that creates a protective zone around the switches and connectors. The internal I-beam construction ensures maximum rigidity while ensuring minimal stress on the sensitive solder joints. These combine to provide exceptional shielding against noise while ensuring greater dependability in the most demanding environments.

The Radial J33 is a high-performance turntable preamp that is ideally suited for music playback, archiving, DJing, and sampling.
