■ Direct Box ■ Passive Type ■ The World's Best DI The JDI is a high-performance passive direct box for live concert tours and professional studio recording applications, featuring premium Jensen transformers for superior audio performance. ■ Features Passive DI with Jensen transformer Eliminates hum and noise caused by ground loops Virtually zero phase and harmonic distortion Excellent signal processing and noise reduction ■ The Pure Sound of the Instrument The Radial JDI is a passive DI box designed to handle extreme signal levels without distortion. The JDI uses the world's best Jensen JT-DB-EPC audio transformer, achieving a smooth, warm Bessel curve reminiscent of vintage equipment. With a completely flat frequency response from 10Hz to 40kHz and almost zero phase deviation, the JDI delivers the natural sound of the instrument without unnecessary coloration. The passive design, which requires no power, converts high impedance to low impedance and balances the signal via a magnetic bridge, transmitting the signal as is while eliminating unwanted DC voltage. This provides excellent performance in effectively eliminating hum and noise caused by ground loops.
