Operating up to 50 metres apart, its impressive UHF digital transmission ensures minimal interference and signal disruption, crucial for maintaining audience engagement during outdoor or crowded events. User comfort is a priority with this tour guide system, as both the transmitter and receiver feature compact designs and robust belt clips, comfortably supporting use on long walking expeditions.

The inclusion of AMEX audio compression-extension means clear vocal transmission and efficient operation immediately. Fully self-contained from day one, the package includes an ergonomically-designed headset mic for the transmitter and discreet earphones for listeners. The banded headset sits discreetly behind your head, providing stable placement and ease of movement.
