Williams AV Interference-Free FM Tour Guide System (TGS PRO MULTI)

The Williams AV TGS PRO MULTI is part of the Personal PA / FM tour-guide line, pairing a compact FM transmitter with one or more wideband FM receivers for one-on-one or small-group listening. Williams AV's FM receivers tune across 17 preset wideband channels (72.1-75.9 MHz), with an OLED display for quick channel selection, and the system is immune to the line-of-sight limits of infrared. It's a common choice for retail and medical point-of-service communication, museum and walking tours, and personal hard-of-hearing use.
