The JR2 is a dual function remote footswitch that lets you switch or mute outputs, depending on the Radial device that is connected.
The Radial JR-2 is an innovative remote control that is equipped with two footswitches - designated as MUTE and AB select. Although designated this way, the actual functionality of the switch depends on the specific Radial product that is connected. The JR-2 connects to the device using a standard balanced audio cable with choice of ¼" TRS or XLR connections. The JR-2 is unique in that it derives its power from the device being controlled which in turn illuminates the on-board LED indicators to show the remote status. Both switches are latching type.
