Radial JDI 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. 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!
