Wireless Tour Guide Systems

Tour guide transmitters/microphones combined with attendee receivers/headsets make up the basic system components for a wireless tour guide system.

One-Way Systems

These systems can be sized to meet your current tour guide requirements and then be expanded as your tour program grows. They are frequency agile and offer 10 user selectable frequencies. Up to four (sometimes five) systems can be operated simultaneously without interference. By combining different frequency bands, up to 13 systems can be operated simultaneously. They can also be combined to handle that large busload of attendees.

These Systems Offer

  • Superior audio clarity, rejection of ambient noise, and naturalness of tone.
  • Sensitive receivers that work even in difficult RF environments
  • Extended battery life. Proprietary low drain circuitry allows receivers to operate 100 hours on two AA alkaline batteries. Transmitters operate 10 to 12 hours on a standard 9V alkaline battery. Rechargeable nickel-metal hydride batteries and a ‘smart’ twelve-port charger are also available.
  • Automatic “shut off” whenever the headphone is unplugged from a receiver. This eliminates dead batteries due to failure to turn switch off while storing system.
  • These systems have been on the market for over twenty-two years. Over this period, the design has been further refined and improved to the point where it offers unrivaled fidelity, sensitivity, durability and flexibility.

Equipment & Accessories

Each system includes a carry case (unless requested as a deduct). A system carry case provides a convenient way to move a tour guide system around, or between, facilities. A large case holds a basic 1 x 15 (1 tour guide, 15 attendee) system. A medium case holds a 1 x 10 system. We configure the case so there is a foam pocket for each receiver. Thus, if at the end of the tour there is an empty pocket, it signifies that someone has not returned their receiver. These are durable, high quality cases that are air tight and waterproof. They can be checked as baggage on an airline without fear of content damage. They do an excellent job of protecting your investment.

All of the RF equipment is manufactured in the United States. It is built to broadcast standards and has excellent shielding. This shielding, combined with sensitive receivers, allows it to work in difficult RF environments. We actually have systems operating inside hydro-electric generating plants that do not experience generator induced electro-magnetic interference.
