The Radial Engineering JDI is a high-performance passive direct box designed for live concert touring and professional studio recording applications. It features a premium Jensen JT-DB-EPC audio transformer that delivers a smooth, warm sound with virtually zero phase distortion and ruler-flat response from 10Hz to 40kHz. The JDI can handle extreme signal levels without distortion, making it ideal for keyboards, bass, and acoustic instruments. Built with a heavy-duty 14-gauge steel chassis, the JDI is designed to withstand the rigors of touring while eliminating hum and buzz caused by ground loops.
