Radial JDI Duplex is a 2-channel passive direct box with numerous input connector types and premium Jensen transformers.




Passive Full-Featured Stereo Direct Box

The JDI Duplex is a high performance 2-channel passive direct box designed for enhanced connectivity for any application, with numerous input connector types and premium Jensen transformers for exceptional audio performance.

 

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 like an ipod, computer or CD player, or professional +4dB line-level audio equipment.

 

Applications:

  • Digital piano, samplers and keyboards  

  • Stereo bass guitar & synth setups  

  • CD, DJ mixers and DVD players   

  • Inputs for line-level +4dB sources

 

Features at a Glance:

  • 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

 

Worth noting (Pro Tip):

You can use the RCA and 3.5mm inputs in tandem with the ¼” inputs. However, please note that if all of the connections are carrying audio at the same time you may have some of the signals overpowering the others, which may require some careful balancing of the source materials to make things sound good as the inputs on the Duplex are simply wired in parallel with each other.

 

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.
