What sets the PRO99 version apart? While the classic Okayo WT-300D offers 25 simultaneous channels, the PRO99 version supports up to 99 simultaneous channels. With 99 channels, interference is a thing of the past. Even if another tour guide uses the same system, the surplus of available channels on the PRO99 is so extensive that frequency overlap and annoying static in tourists’ headphones are virtually eliminated.
Where does it perform best?
-
Handling multiple tour groups at once in a single location: Ideal for logistics around large cruise ships, where dozens of groups collect equipment simultaneously in a single port before setting off.
-
Mass events and conferences: Perfect for simultaneous interpretation into multiple languages (up to 99 distinct language channels at once).
-
Top tourist attractions: In venues like the Louvre, Prague, or the Vatican, where hundreds of guides use tour guide systems, the PRO99 guarantees a clean, interference-free channel.
Key advantages of the Okayo WT-300D PRO99 system:
-
Remote channel switching: Allows the transmitter to change the channel on all paired receivers automatically. No more setting every device manually in large groups!
-
Extreme battery life: The receiver operates for over 35 hours on a single charge.
-
Hearing Aid Compatibility (HAC): Fully accessible for the hard of hearing.
-
Heavy-duty casing: Made of scratch- and crack-resistant ABS material in a new, unique color scheme (purple receivers, black transmitters).
-
Built-in microphone: The transmitter features an integrated mic, handy if external accessories are lost.
The Okayo WT-300D PRO99 model is not compatible with older analog generations WT-300 and WT-300G2 (red receivers/blue transmitters) or the standard digital WT-300D model (turquoise transmitters/purple receivers).
