The Radial JR-5 is a multi-switch remote control
designed for the Radial JX44 Air Control wireless guitar and stage amp switcher.
It features 5 footswitches that can be used to select instruments or amplifiers.
Inside is a programmable memory chip (PIC programmable interrupt controller)
that may be programmed using banks or used in manual mode. A series of five ¼"
momentary contact closures may also be used to translate switch commands from a
MIDI controller to remotely control the JR-5 and JX44
