Equipped with Jensen transformers delivering phase accurate, distortion-free signal, the Radial JDI Stereo is a passive direct box designed to handle extreme signal levels without distortion of any kind. Unlike an active DI that is limited by the buffering amplifier’s rail voltage, the JDI employs a Jensen audio transformer as the engine. Jensen transformers are legendary in their ability to gracefully handle transients while delivering a smooth, warm sounding Bessel curve, reminiscent of the finest vintage gear. Ruler flat from 10Hz to 40 kHz and with virtually zero phase deviation, the JDI delivers the natural, pure sound of the instrument without artefact.

Using only 48V phantom power, the Radial J48 Stereo is an active direct box that produces an exceptionally linear response that extends from 20Hz up to well above 40 kHz. Low distortion of all types is achieved via a unique digital switching power supply that raises the internal operating rail voltage for added headroom and improved signal handling.

MNJ has been writing articles, reviews and blogs for the DV online magazine for the last five years or so. Although he has been playing for longer than he cares to remember and is now officially an 'oldie', he is still mad for all things guitar related and when not busy in his studio he's learning new songs, practising bluegrass guitar, painting his house and taking his dogs out. If banished to a desert island and forced to take only one guitar he'd take a Les Paul. Actually, make that several Les Pauls, a Strat, a Tele, an ES-335, a vintage Martin and some boutique amps. Battery powered obviously.
