It can also be used as a storage case and can put down all the equipment and lanyards, microphones, headphones, and other accessories, a person can easily carry a full set of guide systems.
Silent conference equipment system adopts UHF transmission to ensure the stability of the signal and the clarity of the sound so that the sound penetration is strong, your listeners will not hear annoying noise from the headphones, and they can be more comfortable immersed in the content of the presenter's speech.
The working distance of the transmitter is 200 meters, even if you have a large conference room, and a larger audience, the voice of the presenter can be clearly delivered to the audience in the corner of the conference room.
TT111 ear hook receiver is so light and compact that you can barely feel the weight on your ear, so even if you wear it for a long time, you won't feel any discomfort. In addition, it is suitable for both left and right ears and can be used by people with hearing impairment in one ear. The receiver has a 10-level volume adjustment range, so conference listeners can freely adjust the volume to their desired level with the volume button.
This silent conference equipment system has both manual and automatic pairing options. If you have a lot of receivers, it is a hassle to adjust them to the same channel one by one. However, automatic pairing can synchronize the channels of all receivers and transmitters within 5 seconds to avoid wasting time.
TT111, TT112 audio tour guide system with AUX and MIC interface supports microphone and audio device input at the same time, which means the presenter can play background music while speaking.
The wireless transmitter can work continuously for 10 hours and the mini receiver can work for 8~9 hours. You don't need to charge them frequently, and you don't have to worry about delaying the event process due to equipment power failure during the presentation.

Q: Can I use 2 transmitters on the same channel simultaneously? (For group tour guide scenario with simultaneous speech).
A: This TT112-TT111 tour guide system does not support two transmitters working in the same group. If you want the receiver to listen to two people at the same time, we recommend you use TT106 and TT105, which support two people speaking at the same time.
Q: How to clean and disinfect the headset after use?
A: You just need to wipe it gently with a cotton cloth or cotton swab dipped in alcohol.
Q: What is the warranty on this product?
A: All Retekess guide systems have a 30-day no-reason return and 2-year warranty policy, please refer to Warranty & Return for details.
Q: If demand increases, can I add more receivers?
A: Yes, one transmitter supports working with numerous receivers, if you need additional receivers, just contact us.

The explanation becomes much easier when leading a group in the scenic area. Visitors wearing headphones will not be disturbed by the ambient sound and can listen very attentively. The receiver is also comfortable and durable.
This device does the job perfectly. Easy to operate and always ready to use.It would be better if the logistics could be faster
Our travel agency has equipped all tour guides with TT112, which has improved the quality of their explanations. It is definitely a wise investment and I highly recommend it to my peers!
The training went very smoothly, was easy to operate, and the sound quality was clear. Thank you retekess for your patience and professional service.
The effect of company training has been significantly improved after using TT111! The instructor no longer needs to repeatedly emphasize the key points, and the trainees can hear them clearly through the headphones.
