The Radial JDI is a premium, no-power passive direct injection (DI) box renowned for its exceptional audio transparency and reliability in professional live sound, studio recording, and touring applications. At its core is a Jensen JT-DB-E transformer, which provides ruler-flat frequency response (10 Hz–40 kHz ±1 dB), virtually zero phase and harmonic distortion (<0.001% THD), and outstanding common-mode noise rejection to eliminate ground loops and hum without any active circuitry. Designed to handle extreme signal levels from high-output sources like active guitars, basses, keyboards, and digital instruments, the JDI delivers warm, artifact-free sound reminiscent of vintage gear—making it the industry standard for engineers seeking uncolored, high-fidelity instrument interfacing.
