What makes the PRO99 version stand out? While the classic Okayo WT-300D offers 25 simultaneous channels, the PRO99 version supports up to 99 simultaneous channels. With 99 channels at your disposal, you no longer need to worry about other guides or devices nearby. Even if another guide is using the same system, the surplus of available channels in the PRO99 version is so vast that the risk of frequency overlap and annoying interference in tourists’ headphones is practically eliminated.
Best Use Cases:
-
Managing Giant Tour Groups: Ideal for logistics at major cruise terminals, where dozens of groups disembark and start their tours simultaneously.
-
Mass Events and Congresses: Perfect for simultaneous interpretation into multiple languages (up to 99 different language channels at once).
-
Top Tourist Attractions: In crowded sites like the Louvre, Prague, or the Vatican, where hundreds of guides use tourguide systems, the PRO99 guarantees a clear, interference-free channel.
Key Advantages of the Okayo WT-300D PRO99 System:
-
Remote Channel Switching: Allows the transmitter to automatically change the channel on all paired receivers. No more manual adjustments for every single device in a large group!
-
Extreme Battery Life: The receiver operates for over 35 hours on a single charge.
-
Hearing Aid Compatible (HAC): The system is fully accessible for people with hearing impairments.
-
Armoured Housing: Made of scratch- and crack-resistant ABS material in a new, unique colour scheme (purple receivers, black transmitters).
-
Built-in Microphone: The transmitter features an integrated microphone, useful if an external accessory is lost.
The Okayo WT-300D PRO99 is a digital system and is not compatible with older analogue generations (red receivers/blue transmitters).
