The Radial JDI is widely regarded as the world’s finest direct box. It features the legendary Jensen JT-DBE transformer, known for its warm Bessel response curve. With virtually zero phase distortion, exceptional signal handling, and true transformer isolation, the Radial JDI eliminates hum, making it a top choice for live sound reinforcement.
As a completely passive, plug-and-play unit, the JDI requires no power, helping to eliminate 60-cycle ground loops. This feature makes the JDI a favorite among knowledgeable audio engineers. The JDI is ideal for guitars, bass, keyboards, and particularly high-output broadband instruments, such as active instruments and digital keyboards. The JDI can be rack-mounted using the J-Rak and is also available in a stereo (2-channel) version called the JDI Duplex, as well as a 6-channel rack-mountable version, the JD6.
