The JR1M from Radial is a momentary footswitch that can control various Radial devices, such as the Relay Xo stereo switcher, and is designed to remotely control functions such as switching between A and B outputs. The momentary footswitch changes states only when held down and subsequently released and is a well suited for 'push-to-talk' uses like toggling to an intercom system to speak with stage technicians.
The footswitch can also function in passive mode, allowing it to function as a standard footswitch for any device with a compatible 1/4" footswitch jack. When used for this purpose and set to active mode, the footswitch derives power from the device under control, thus eliminating the need for a local power supply or batteries.
