Radial Engineering JDI Duplex Jensen Stereo Passive DI For Active Bass, Acoustic & Keyboard
The Radial JDI Duplex 2-channel passive direct box delivers great sound and rock-solid reliability, whether you use it onstages or in the studio. The JDI Duplex features Jensen transformers to give you the best performance possible at all frequencies. This box can handle very high signal levels without distorting, and its passive design helps to eliminate 60-cycle ground loops. Great for everything from passive and active guitars and basses to analog and digital keyboards, the Radial JDI Duplex is a dependable, quality performer!
FEATURES
- Welded I-beam construction makes it impossible to torque the PC board. This virtually eliminates cold solder joints - the No.1 cause of system failure in the field.
- An innovative 'slide-in-place' XLR trace makes it possible to use I-Beam girder construction.
- Jensen transformer for distortion-free performance.
- A military-grade PC board is employed for maximum wear and tear in abusive environments. Welded steel standoffs ensure the PC board will not shift.
- A -15dB pad allows super hot inputs such as that from a CD player to be connected and balanced for long runs.
- The Merge function turns the input and thru into a passive mixer to sum stereo feeds to mono at the XLR output. This saves valuable inputs on the mixer!
- The input connects to the instrument.
- The thru-put is connected to the instrument amplifier. The JDI has a high input impedance to reduce loading.
- Our book-end design creates a protective zone around the switches & connectors for best protection!
- A heavy-duty baked enamel finish for excellent durability and great looks for years! 100% 14-gauge steel construction.
- The XLR balanced mic level output provides 100% isolation for runs to 1000 feet without appreciable noise.
- A polarity reverse switch flips the polarity from the AES standard Pin-2 to Pin-3 on the XLR and is used when combining sounds that may be out of phase.
- The ground-lift disconnects the ground path to the transformer at the XLR output. This is used when a ground path is made at the input side such as with a keyboard.
- The parallel speaker interface option introduces a second -30dB pad with band-pass filter to emulate a 12" guitar speaker.
- A no-slip full bottom pad reduces mechanical vibration, improves electrical isolation and keeps the JDI from moving around on busy stages!
