Clear and accurate audio quality

  • Enhanced digital stereo encoder provides a wider stereo field with exceptional separation, enhancing audio detail and clarity
  • Patented Audio Reference Companding sounds more like wired

Robust RF performance

  • Precision front-end RF filtering, the same found in industry-leading UHF-R wireless systems, significantly reduces RF interference for a cleaner, stronger RF signal, fewer dropouts, and less audible artifacts
  • Exceptional transmitter linearity vastly reduces frequency intermodulation, allows up to 20 compatible channels per frequency range
  • Auto RF gain control prevents signal distortion due to RF overload before it can affect performance

Innovative setup and operation features

  • Patent-pending CueMode allows monitoring of different stage mixes and storing of up to 20 separate channels on one bodypack for quick and easy reference
  • Front Panel RF mute switch for enabling or disabling RF transmission
  • Use Scan and Sync to scan the RF environment with the bodypack and assign the identified group and channel to your system over wireless IR link
  • MixMode Technology allows the bodypack user to balance the level of two separate channels while simultaneously listening to both signals in both ears
  • LCD menu with grouped menu items for easier user interface

James Stoffo, Entertainment RF Engineer and „wireless guru“ about PSM 900 at the Super Bowl 2010

This was my first time using the PSM 900 at a major event, and it performed flawlessly. I’d be happy to see this system on any of my shows as the go-to in-ear system.
