Radial JDI Duplex Passive DI, 2-chan for keyboards with 1/4", RCA, 3.5mm & XLR inputs

Description Radial JDI Duplex Passive DI, 2-chan for keyboards with 1/4", RCA, 3.5mm & XLR inputs Passive Full-Featured Stereo Direct Box The Radial JDI Duplex is a high performance 2-channel passive direct box professionally designed for enhancing the connectivity for any application, with numerous input connector types and premium Jensen transformers for exceptional audio performance. The Radial JDI Duplex is a high performance dual-channel direct box professionally designed for providing maximum flexibility for the audio engineer in the most demanding applications. It comes with two custom-made nickel laminated transformers designed for optimal signal transfer with absolute minimal distortion of all types. Analysis reveals an exceptionally linear response from 10Hz to 40kHz alongside virtually zero phase shift at all critical frequencies. The excellent performance is shown greatly and with added with a Fast Fourier transform capable of producing a desirable even order harmonic generation and a warm Bessel curve when pushed hard. With the Radial JDI Duplex's heavy-duty steel shell and internal I-beam construction, it is designed to work dependably for years in the most stressful of touring environments. A full complement of connectors is making the Duplex a God-send when faced with the seems infinite challenges of professional touring, broadcast and AV integration. 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.
