The Radial JDI 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 40kHz and with virtually zero phase deviation, the JDI delivers the natural, pure sound of the instrument without artifact.

Jensen Transformer equipped passive DI
Eliminates hum and buzz from ground loops
Virtually zero phase & harmonic distortion
Exceptional signal handling and noise rejection
