Direct Box filter, Powered via 48V.
The Radial J33 is a combined high resolution phono preamplifier and stereo direct (DI) box, with an extremely robust design with the build quality to withstand the scraps and bangs of both the professional recording studio and a live touring environment.
The Radial J33 has been designed specifically for dynamic cartridges with Low noise RCA inputs that are fitted with a turntable ground lug. A precise RIAA low pass filter is fitted tailored to produce a clear smooth audio 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 1/4" jack for an audio recorder. A second set of DI XLR outputs deliver a mic level signal to feed multicore, mic splitter and mixing desk preamp inputs. A low pass filter is also fitted for high sound pressure environments to reduce bothersome resonant feedback.
The J33 features a 14 gauge steel enclosure- a unique book-end design creates a protective zone around the switches and input connectors. An internal I-Beam construction ensures maximum rigidity, ensuring minimal stress on the sensitive internal solder joints.
The Radial J33 is a high performance turntable preamp ideally suited for music playback, archiving, DJing and sampling.
