Radial J33

Fully outfitted for hi-fi archival and rugged enough for stage performances.

A combination RIAA phono-turntable preamp and direct box that allows long-play vinyl albums to be played directly through a professional microphone preamp or mixing console where the very highest quality is required. This audiophile interface is ideally suited for album archiving, pristine sampling, recording performances, and DJ mixing. It has RCA inputs; stereo RCA, 3.5mm, and 1/4" TRS -10dB line-level outputs; and balanced mic-level XLR outs. Employs an indestructible steel housing with internal I-beam construction, a protective zone around switches and jacks, and a full-bottom no-slip pad. May be powered with 48V phantom or DC supply. An auto sensor automatically selects whichever power supply is present.
