Radial J33 Combination RIAA phono Preamp and DI box.

Description

The Radial J33 is a combination ofa purpose built DI box with a Phono preamp built in. It is built for the professional musician, with its fantastic audioperformance and quality construction able to withstand a life constantly in use at the studio or on the road.
Here’s what Radial say about the J33
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 choice of RCA connectors for compatibility with home HiFi entertainment systems, 3.5mm (1/8″) output to feed a laptop or iPod, or a stereo TRS ” jack for an audio recorder. A second set of direct box XLR outputs deliver 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 book-end 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.
