Williams Sound Digi-WAVE Tour Guide System 20
The WS-DWSTTGS20 is a Digi-WAVE one-way tour guide system by Williams Sound. It will allow the tour guide to better communicate with up to 20 people who are hard of hearing! The kit can be expanded with an unlimited number of receivers, just as long as they are within range of the transmitter. This system requires no base station, so it is extremely portable and completely wireless. This kit operates on the 2.4 GHz ISM band and utilizes GFSK modulation with patented frequency-hopping software to reduce interference.
