PSM 300 SE112 Stereo Personal Monitor Systems deliver reliable wireless freedom to every corner of the stage. Patented Audio Reference Companding ensures the clearest sound, with ultra-low noise and no artifacts. 

Easy to setup and operate, PSM 300 systems offer one-touch frequency scan and sync to find and assign a clean wireless channel. Adjust the volume and use MixMode technology or stereo mode to create a personal mix from two channels of audio.
