The TT129 wireless full-duplex communication system allows up to 3 speakers to talk simultaneously and engage in real-time conversation, with no limit on the number of listeners. It perfectly solves the pain points of information transmission delays and inefficient collaboration in scenarios such as large group tours, factory receptions, group discussions, and multi-speaker training, achieving seamless and efficient communication.
TT129 wireless tour guide system is a new group communication device that supports three transmitters operating at the same time. It supports 3 speakers speaking simultaneously, with an unlimited number of listeners. The 3 transmitters can talk to each other and hear both their own voices and the voices of others. The receiver can hear the voices of all 3 speakers at the same time.
With a 20-hour battery life for the transmitter and a 120-hour battery life for the receiver after just 5 hours of charging, the TT129 wireless tour guide system ensures uninterrupted use throughout long visit days.
Up to 100m between the main and secondary transmitters, and up to 200m between the transmitter and receiver in open spaces, the TT129 wireless tour guide system ensures clear communication even in expansive environments.
With 4 levels of intelligent noise reduction, you can adjust the settings to suit your specific environment, whether you're in a noisy training facility or a bustling academic conference. Easily adjust the intelligent noise reduction level with a simple long press of the ANC button on the transmitter, allowing you to adapt to changing environmental conditions throughout the day.
Fast charging via the Type-C port or the convenience of the charging case. It's ideal for powering through long conferences, field surveys, and all-day training courses.
The TT129 wireless guide system earphones feature a universal design that fits both left and right ears comfortably with ergonomic D-shaped earbuds, catering to different user preferences.
The lavalier microphone headset keeps your hands free for gesturing or handling materials, making it suitable for guided tours, training workshops, or research discussions where multitasking is essential.
The interface between the microphone and the earphone is tight and must be fully inserted; otherwise, the audio quality may be poor or the signal may not connect properly.
1. Meetings and training: multiple hosts or lecturers
In meetings or training sessions that require multiple lecturers or hosts to discuss together, the three-transmitter function of TT129 allows each lecturer to speak at the same time to avoid delays or duplication in information transmission.
Examples:
Expert panel discussion: Three experts give their opinions on different aspects of a topic, and participants hear the views of all three experts at the same time through the receiver.
Multi-lecturer training: Three lecturers are responsible for different training modules and interact with trainees.
TT129's simple operating interface and intuitive display design allow lecturers to easily switch channels, adjust volume, or enable mute functions during meetings or training to improve communication efficiency.
2. Tour guides: three guides working together
The three-transmitter function of TT129 is particularly important for large tour groups or multilingual tourists. Each guide is equipped with a transmitter (M, S, R) and can explain different topics or languages separately, ensuring that all tourists can hear the explanation clearly.
Examples:
Historical site explanation: One guide explains the historical background, another explains the architectural details, and the third answers tourists' questions.
Multilingual explanation: For tourists speaking different languages, three guides can explain in different languages, ensuring information is conveyed smoothly.
TT129's 999-channel selection and 4-level intelligent noise reduction function ensure a clear audio experience even in noisy environments.
3. Factory tour: multiple receptionists guide
In factory tours, multiple receptionists are often required to explain different production areas or process flows separately. The three-transmitter mode of TT129 enables each receptionist to speak independently, ensuring that the information is conveyed clearly and without duplication.
Examples:
Production process explanation: One receptionist explains the operation of the production line, another explains the quality control process, and the third introduces safety regulations.
TT129's 120-hour receiver battery life is suitable for long factory visits.
