Tour guide systems (also called personal guide systems, whisper systems or simultaneous interpretation systems) transmit the voice of a guide or interpreter wirelessly to a group of listeners — discreetly, without interfering noise and without cables. Typical applications: museum tours for deaf or hard-of-hearing visitors, factory and production site tours in noisy environments, city tours and educational trips, conferences and AGMs with simultaneous interpretation, training in industrial facilities with mandatory hearing protection.

System structure and components: The transmitter is worn by the guide — with a lavalier mic clipped to the lapel or a headset for hands-free operation. Each participant receives a receiver with earphone (in-ear or over-ear). One channel can be received by unlimited participants simultaneously — typical systems support 1–32 channels in parallel (simultaneous interpretation into multiple languages). Transmission technologies: UHF radio (470–694 MHz): range 50–100 m, no line-of-sight required — the most widespread technology. 2.4 GHz DECT: digital transmission, lower interference susceptibility, range approx. 30–50 m. Infrared (IR): absolutely tap-proof (no signal outside the room), requires line-of-sight to IR emitter — ideal for conferences and confidential simultaneous interpretation.

Buying vs. renting — what to consider: For permanent use (museum, factory, training centre) purchase is worthwhile. Systems are modularly expandable — additional receivers can be added at any time. Charging cases charge all receivers simultaneously and serve as transport containers. Batteries: Li-Ion, runtime 8–20 h depending on model. Monacor with the TourGuide family and RCS Audio-Systems with Microflex Wireless offer professional solutions with excellent speech intelligibility, robust plastic housing and easy operation even for non-technicians.
