JDL Passive Direct Box

The Radial JDI is a passive direct box designed to handle extreme signal levels without distortion of any kind. Unlike an active DI that is limited by the buffering amplifier’s rail voltage, the JDI employs a Jensen audio transformer as the engine. Jensen transformers are legendary in their ability to gracefully handle transients while delivering a smooth, warm sounding Bessel curve, reminiscent of the finest vintage gear. Ruler flat from 10Hz to 40kHz and with virtually zero phase deviation, the JDI delivers the natural, pure sound of the instrument without artifact.

Features

  • Welded I-beam construction makes it impossible to torque the PC board. This virtually eliminates cold solder joints - the No.1 cause of system failure in the field.
  • An innovative 'slide-in-place' XLR trace makes it possible to use I-Beam girder construction.
  • Jensen transformer for distortion-free performance.
  • A military-grade PC board is employed for maximum wear and tear in abusive environments. Welded steel standoffs ensure the PC board will not shift.
  • A -15dB pad allows superhot inputs such as that from a CD player to be connected and balanced for long runs.
  • The Merge function turns the input and thru into a passive mixer to sum stereo feeds to mono at the XLR output. This saves valuable inputs on the mixer!
  • The input connects to the instrument.
  • The thru-put is connected to the instrument amplifier. The JDI has a high input impedance to reduce loading.
  • Book-end design creates a protective zone around the switches & connectors for best protection!
