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.
