Description

Passive Full-Featured Stereo Direct Box

The JDI Duplex™ takes the world’s finest passive direct box one step further, providing numerous connector types to easily interface with any sound source – including line-level devices – while maintaining the highest audio quality and transparency.

Features

  • Jensen transformer equipped passive DI
  • Eliminates hum and buzz from ground loops
  • 1/4″, 3.5mm, RCA, and XLR inputs to connect to any source
  • Exceptional signal handling and noise rejection

Unparalleled tone, multiple connector options

The JDI Duplex takes the exceptional transparency and wide bandwidth of the JDI Stereo passive direct box, and adds numerous connector types and line-level inputs to provide the audio technician with the ability to interface with any stereo sound source. Designed to handle extreme signal levels without distortion, it utilizes two world-class Jensen JT-DB-EPC audio transformers to deliver 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 Duplex delivers the natural, pure sound of the instrument without artifact. The inputs can be accessed via 1/4", RCA, 3.5mm TRS, or XLR line-level connectors, making it easy to plug in any sound source, from stereo instruments to consumer playback equipment, or professional +4dB line-level audio equipment.

JDI Duplex Applications

  • Duplex in Multimedia System
    • Whether you have a CD player, iPod, computer or professional +4dB balanced source, the Duplex can handle any situation.
  • Duplex with Stereo Keyboard
    • The Duplex is able to withstand huge transients without distortion. This gives digital keyboards a warm, smooth vintage tone.
  • Duplex with Two Stereo Sources
    • With the dual stereo architecture, the Duplex can easily be set up to handle two different stereo sources at the same time.

Specifications

Radial JDI Duplex is a high performance dual-channel direct box that is designed to provide maximum flexibility for the audio engineer in the most demanding applications. It features two custom-made nickel laminated transformers for optimal signal transfer with absolute minimal distortion of all types. Analysis reveals an exceptionally linear response from 10Hz to 40kHz with virtually zero phase shift at all critical frequencies. The excellent performance is further substantiated with a Fast Fourier transform that produces desirable even order harmonic generation and a warm Bessel curve when pushed hard. With its heavy-duty steel shell and internal I-beam construction, the Duplex is designed to work dependably for years in the harshest of touring environments. A full complement of connectors make the Duplex a God-send when faced with the never-ending challenges of professional touring, broadcast and AV integration.
