The Radioguide Duo by Crystal Sound is a professional two-way tour guide communication system designed for industrial visits, trainings, conferences and corporate events where interaction and dialogue are as important as clear audio transmission.
Unlike traditional one-way radioguides, Radioguide Duo is a bidirectional intercom system.
It allows participants not only to listen to the guide, but also to speak, ask questions, and interact in real time, creating a more engaging and participatory experience.
Radioguide Duo uses a Push-to-Talk intercom system.
Participants can transmit their voice by pressing and holding a button on their receiver, while guides and speakers use transmitters with headsets. Communication is intuitive, controlled, and interference-free.
The system supports up to 4 simultaneous speakers (transmitters and/or participants) and an unlimited number of listeners, making it ideal for interactive tours, Q&A sessions, and group coordination.
Radioguide Duo provides a stable signal range of up to 150 meters, ensuring reliable communication even in dynamic, outdoor, or noisy environments.
Devices are synchronized using CS. Tap&Connect, Crystal Sound’s one-button pairing system.
Transmitters and receivers are paired quickly and remain synchronized for future use, reducing setup time during daily operations.
Thanks to AI-based automatic channel selection, the system chooses the optimal channel based on the environment, eliminating manual setup and ensuring interference-free communication. Devices remain paired for future use, reducing setup time for daily operations.
