This package includes 2 IRC-21 Emitter/Modulator Panels with power supplies, mounting brackets and manual.
Support for over 350 seats or 11,000 square feet.
The UPC-21 Infrared Transmission Systems use light emitting diodes frequency modulated at 95kHz, the international standard.
The modulated waves radiate from the emitter panels primarily in straight lines. Depending on the lightness of the wall color, some of this energy may be reflected and bounce around the room. Infrared energy does not penetrate walls. The modulated waves remain within the room where the emitter is placed. This feature makes it perfect for use in multiplex theatre units and for use in hotel and convention center meeting rooms and auditoriums. Additionally, this characteristic of infrared transmission makes it ideal for meetings requiring security of the signal.
USL, Inc. provides the following 95kHz headsets:
IRH-501 � an over-the-head receiver designed with a 360� pickup.
IRH-701 � an under-the-chin receiver with an approximate 270� pickup.
