30-Person Portable RF System (72 MHz) (Discontinued)


The LS-13 30-Person Tour Group System is a great for organizations that need a fair number of people to understand the message of one guide. This system is ideal for class field trips, site-seeing tours and language interpretation as well. The 30-Person System includes a portable transmitter and microphone, display receivers with ear speakers, batteries and a carrying case. Also be sure to consider whether a hand held or noise canceling microphone might be appropriate for your application. You can add any number of receivers to a single transmitter if you need to accommodate more guests. This system is a good size for rentals. Use this system for auditory assistance and language interpretation on tours, for events or in other venues. Great for schools, manufacturers, museums, governments, houses of worship, tour companies, busing companies, zoos, and board rooms.
