Shure PSM900-K1E In-Ear Monitor System

Full Description

RF reliability

Packed full of functionality to improve RF stability, the PSM900 system is built to prevent radio frequency interference as well as avoiding dropouts and digital artefacts. Additional automatic RF gain control prevents distortion for clear, uncoloured sound throughout its use, no matter how high you need the volume cranked.

Highly expandable

Capable of broadcasting up to 20 channels on one frequency band, the PSM900 system can expand to fit the demands of your performance space and setup. With the ability to dynamically switch between up to 20 different stage mixes, any musician can hear exactly what they need to. Thanks to its compact half-rack design, it's easy to integrate and chain multiple systems together for multiple performers. With reduced frequency intermodulation, you can be assured that expanding your system won't add noise or interference to your system.

Clear, accurate sound

The key to any quality monitoring system is an uncoloured, accurate sound to ensure that performers can hear their work clearly and accurately. Thanks to the system's detailed RF filtering to prevent distortion and artefacts, the PSM900 system is incredibly capable of delivering quality you can rely on.
