Radial Engineering JDI Premium Passive DI

The Radial Engineering JDI is a passive direct box designed to handle extreme signal levels without any distortion. At its core, the Radial JDI features the world-class Jensen JT-DB-EPC audio transformer, delivering a smooth, warm Bessel curve reminiscent of the finest vintage gear.

With a ruler-flat frequency response from 10Hz to 40kHz and virtually zero phase deviation, the Radial Engineering JDI provides the natural, pure sound of the instrument without artifacts. Its passive, no-power design allows the Radial JDI to perform high-to-low impedance conversion and signal balancing over a magnetic bridge, which passes the signal while rejecting stray DC voltage.

This makes the Radial Engineering JDI particularly effective at eliminating hum and buzz caused by ground loops.

Features

• Jensen Transformer equipped passive DI
• Eliminates hum and buzz from ground loops
• Virtually zero phase & harmonic distortion
• Exceptional signal handling and noise rejection

JDI with Electric Bass
The JDI is often selected for high output bass guitars. It is able to handle huge signal levels without distortion or artifact. On stage it sends the pure sound of the bass to the PA with minimal loading. In studio, it is perfect for recording direct.

JDI with Acoustic Guitar
Most acoustic guitars have built-in preamps that can be peaky. The JDI naturally smoothes out the transients for a warmer tone. And because the JDI is able to handle huge transients, it will not distort. This makes the JDI a great direct box for acoustic guitars.

JDI with Keyboards
Today’s digital keyboards are not only very dynamic, but some like digital pianos also have a tremendously wide frequency response. The Radial JDI is able to withstand excessive signal levels at all frequencies without introducing distortion or phase shift.

The Radial JDI is a phase coherent, passive direct box employing a nickel laminated Jensen® audio transformer with virtually zero phase distortion, huge dynamics handling and ruler flat response from 10Hz to 40kHz. The Radial JDI is quite simply the world’s finest passive direct box. With its heavy-duty steel shell and internal I-beam construction, the JDI is designed to work dependably for years in even the harshest of touring environments. Ideal for keyboards, bass and acoustic instruments of all kinds, the JDI Duplex and JD6 are also available for stereo and multi-channel applications.
