The Fonestar TOUR-TXBASE is a desktop wireless transmitter developed for clear, professional communication during guided tours and cultural visits. It can also be used for simultaneous translation or for hearing assistance with a personal induction loop.
Its robust design and efficient, interference-free transmission allow it to send audio to an unlimited number of non-bidirectional TOUR receivers on the same channel. It operates in the licence-free 863 - 865 MHz band, with a range of up to 100 m (extendable to 400 m with a directional antenna and/or antenna amplifier, not included).
