From Radial Engineering
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.
