About this listing
The Radial JDI Duplex Passive Direct Box is a full-feature, passive stereo direct box designed to enhance connectivity, reduce noise, and deliver the utmost in sonic quality. Employing two of the worlds' finest Jensen audio transformers, the JDI Duplex delivers exceptional signal handling with virtually zero phase shift or harmonic distortion. The Radial JDI Duplex Passive Direct Box has often been dubbed the swiss army Knife' of direct boxes. And there is good reason for that. a real swiss-made knife combines tons of useful tools into a small, yet very functional package and if handled correctly, will provide a lifetime of service! The Radial Duplex is exactly the same. The Radial JDI Duplex simplifies the hectic life of the touring professional, broadcast engineer or AV integrator. It is plug-and-play easy to use while delivering the utmost sonic quality. Like the , the Radial JDI Duplex employs two high-performance Jensen audio transformers with the same pristine audio signal path that has made the Radial JDI Duplex the industry standard. It features exceptional signal handling with virtually zero phase shift or harmonic distortion, while remaining linear across the entire audio spectrum. When driven to extremes, the natural transformer saturation and resulting warm Bessel curve makes the Radial JDI Duplex the perfect choice for smoothing out highly dynamic instruments such as digital pianos and electronic drums that can sound harsh when pushed. Transformer isolation provides the additional benefit of eliminating troublesome ground loops that can cause hum and buzz in the audio system or interfere with video displays. This 'Swiss Army knife' Radial JDI Duplex is equipped with ¼" connectors for instruments, RCA connectors and a 3.5mm TRS for unbalanced -10dB consumer electronics plus XLR inputs for +4dB professional line sources. Radial's innovative book-end design provides protective zones on the front and rear to keep connectors and switches out of harm's way. The 14 gauge I-beam inner frame adds tremendous rigidity to eliminate outside stresses that could torque the PC board and cause premature solder joint and trace failure. The steel outer shell couples with the transformer's MuMETAL® shield to protect against stray magnetic fields from power transformers or lighting systems that could cause interference. Finally, a full-bottom no-slip pad works double-duty by providing both mechanical and electrical isolation. The Radial JDI Duplex delivers outstanding connectivity, superlative audio and quiet dependable performance. The Radial JDI Duplex the world's finest passive stereo direct box. Radial JDI Duplex Passive Direct Box Features Stereo direct box for high output sources Ultra linear response from 10Hz to 40kHz Virtually zero phase & harmonic distortion Eliminates hum and buzz from ground loops Linear response from 10Hz ~ 40kHz Enhanced connectivity with ¼, RCA, and XLR inputs Extraordinary level handling without distortion Built to handle the rigors of live touring Plug & play, easy-to-use! Transformer isolation eliminates hum & buzz No battery or phantom power required Makes just about anything sound better!
