  • Link output to switch multiple units at once

Reroute signals on stage

Designed to address on-stage communication problems for artists who employ in-ear monitoring systems, the Relay Xo is a remotely controlled active switcher that enables artists on stage to quickly reroute their signal without disrupting the performance. Connect the output of a dynamic microphone or wireless receiver to the Relay Xo input, then feed output-A to the PA system, and output-B to a common intercom buss. As soon as the Relay Xo is switched, it cuts the signal feeding the PA and redirects it to the monitoring system, allowing the musician to discreetly speak with other band members or the crew.

Remote access

When artists that employ wireless microphones on tour, the receivers are typically located off stage. The remote input on the Relay Xo allows it to be connected next to the wireless receivers to reduce cable clutter, while still providing control to the artist on stage with a remote footswitch. Two versions of the Radial JR1 footswitch are available for use with the Relay Xo; the JR1-M with a momentary switch that will activate output-B as long as the footswitch is held down, and the JR1-L with a latching switch that will hold on the last selected output.
