Wireless In-Ear Monitor System


The M2 Wireless In-Ear Monitor System is designed to make professional in-ear monitoring features accessible for performers who want to be free from the problems associated with floor wedges. The stereo monitor system offers Personal Mix Control, which gives each musician volume and mix control of two independent signals on stage, via easy-to-use controls on the M2R stereo body-pack receiver. The wireless UHF M2T Stereo Transmitter provides a choice of 100 selectable frequencies and is equipped with two XLR/¼” combo input connectors into which users can connect line-level inputs. While up to 10 complete M2 systems may be used on stage simultaneously, any number of M2R stereo receivers may be used on the same frequency with a single M2T stereo transmitter. These rugged systems are built to stand up to the inevitable bumps of life on the road, delivering clear, natural sound for touring and installed-sound uses.
