Additional Information for: Radial Engineering
The JDI is a high performance passive direct box for live concert touring and professional studio recording applications, featuring a premium Jensen transformer for exceptional audio performance.
The Radial JDI is a passive direct box designed to handle extreme signal levels without distortion of any kind. At the heart, the Radial JDI employs the world class Jensen JT-DB-EPC audio transformer 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. By its no-power passive design, the Radial JDI performs both high-to-low impedance conversion and signal balancing over a magnetic bridge that passes signal while rejecting stray DC voltage. This makes the JDI particularly adept at eliminating hum and buzz caused by ground loops.
The AC-Driver is an acoustic instrument preamp designed for use on stage, with helpful features to streamline your performance and ensure the best possible tone from your instrument.
