What distinguishes the PRO99 version?
While the classic Okayo WT-300D version offers 25 simultaneous channels, the PRO99 version supports as many as 99 simultaneous channels. With 99 channels, you don’t have to worry about interference. Even if another guide uses the same system, the ample availability of free channels in the PRO99 version virtually eliminates the risk of wave overlap and annoying crackling in tourists’ headphones.
Where will it perform best?
- Handling a large number of tourist groups simultaneously in one location: Ideal for logistics with large passenger ships (cruisers), where dozens of groups simultaneously pick up equipment and depart for sightseeing at a single port.
- Mass events and congresses: Excellent for simultaneous interpretation into many languages (up to 99 different language channels simultaneously).
- Most popular tourist attractions: In places like the Louvre, Prague, or the Vatican, where hundreds of guides use tour guide systems, PRO99 guarantees a clear channel without interference.
Key advantages of the Okayo WT-300D PRO99 system:
- Remote channel change: Allows the transmitter to automatically change the channel on all paired receivers. No more manual setup of each device in a large group!
- Extreme battery efficiency: The receiver operates for over 35 hours on a single charge.
- Hearing Aid Compatible (HAC): The system is fully accessible for individuals with hearing impairments.
- Armored casing: Made of scratch and crack-resistant ABS material in a new, unique color scheme (purple receivers, black transmitters).
- Built-in microphone: The transmitter has an integrated microphone, useful if an external accessory is lost.
The Okayo WT-300D PRO99 model is not compatible with older analog generations WT-300 and WT-300G2 (red receivers/blue transmitters) and the digital model WT-300D (turquoise transmitters/purple receivers).
