Shure PSM900 wireless in-ear personal monitor (IEM) system

Shure PSM900 in ear personal monitor


The Shure PSM 900 wireless In-Ear Personal Monitoring System  (IEM) offers a clear and accurate audio quality and robust RF performance. Innovative features allowing for ease of use and quick setup make the Shure PSM900 the ideal solution for the most demanding professional applications. All new, patent-pending CueMode allows the sound engineer to monitor different stage mixes with the touch of a button. Precision front-end RF filtering significantly reduces dropouts from RF interference.

We supply our Shure PSM900 IEM systems complete with Shure SE425 earphones unless otherwise specified, and a small charge will be made for disposable hygienic foam sleeves. Additional receivers can be hired separately if required.
