Condition
This items is in great working condition. There are scratches on its casing. There are some scratches on the foam mat on the bottom. When I bought the item it didn’t have the bottom two plastic 1/4 inch nuts that screw on the jacks so I added two new non OEM plastic nuts.
Overview
The Radial JDI Duplex is a full-feature, stereo passive direct box designed to enhance connectivity, reduce noise, and simplify 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 Radial JDI, the Duplex employs two high-performance Eclipse audio transformers and the same pristine audio signal path that has made the JDI 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 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.
This Swiss Army knife DI is equipped with ¼ inch connectors for instruments, RCA connectors for unbalanced -10dB consumer electronics and 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 mu-metal 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.
Features & Functions
1. HI-CUT FILTER: Works when the PAD is engaged to reduce hiss and noise.
2. -15dB PAD: Allows loud signals from keyboards to be connected without distortion.
3. MERGE: Turns the input and thru jacks into a passive mixer to sum stereo signals to mono.
4. ¼ inch PHONE & RCA JACKS: For instruments and line-level sources like CD players.
5. XLR-IN: Activates the +4dB XLR input and disconnects the ¼” & RCA jacks.
6. BOOK-END DESIGN: Creates a protective zone around the jacks and switches.
7. +4dB XLR INPUT: For balanced line-level sources like mixing consoles and pro VTRs.
8. 180° POLARITY REVERSE: Inverts signal polarity at the XLR output to help align phase when mixing with mics.
9. XLR OUTPUT: 600 Ohms balanced mic-level output for runs to 1000′ (300m) without noise.
10. GROUND LIFT: Helps reduce noise caused by ground loops; lifts pin-1 on both channels.
11. FULL BOTTOM PAD: Improves electrical insulation and mechanical isolation.
12. I-BEAM REINFORCED: 14-guage steel enclosure with extra stiff i-beam shape makes it impossible to torque the PC board and eliminates cold solder joints. Durable baked enamel fi nish.
