Radial Engineering JDI Stereo
2-Channel Passive Direct Box with Jensen Transformers

OUR PART #  JDI-STEREO


The Radial Engineering JDI Stereo is a passive stereo 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 pair of Jensen audio transformers that at once balance the signal and lower the impedance to drive long cables. No power is required. You simply plug in and it works.

Radial Engineering JDI Stereo Features:

  • Jensen Transformer equipped passive DI
  • Eliminates hum and buzz from ground loops
  • Virtually zero phase & harmonic distortion
  • Compact stereo format for twice the performance

Radial Engineering JDI Stereo Specifications:

  • Audio circuit type: Passive, transformer based
  • Number of channels: Two channels (dual mono)
  • Frequency response: 20Hz ~ 20KHz (± 0.2dB)
  • Dynamic range: 135dB
  • Maximum input: +21dB @ 20Hz ~ 20kHz
  • Total harmonic distortion: 0.05% from 20Hz ~ 20kHz@-10dB
  • Phase deviation: 0.3° @ 100Hz; 3° @ 20Hz
  • Input impedance: 140k Ohms, unbalanced
  • Output impedance: 150 Ohms, balanced
