Tourtalk TT 21 system
Tourtalk TT 21 is a digital portable wireless communication system that helps the presenter(s) to speak to a group of people when needing to overcome background noise and distance.
The system enables up to two presenters to speak at a comfortable level, ensuring they are clearly heard. The system has 42 channels and up to 15 separate groups can operate within the same environment, with no limit to the size of each group.
The lightweight and compact Tourtalk TT 21-T transmitter has an integrated microphone, audio input socket, mute switch and features wireless channel syncing. Two transmitters can operate on the same channel enabling two presenters to address the same group. Alternatively, the main presenter can use one transmitter and pass the other transmitter for interviews, questions, or simultaneous interpretation (for any foreign guests), ensuring everyone hears. The Channel sync function enables the transmitter to wirelessly sync its channel to a batch of receivers.
The Tourtalk TT 21-R receiver is integrated into a single earphone! This innovative device is issued to each member of the group to hear the presenters. The receiver features a simple two button operation and can be used on the left or right ear. This ensures the user can hear the presenters without feeling isolated from the local environment enabling them to experience the atmosphere and be aware of any potential dangers such as traffic.
The wireless one-piece single earphone design makes distributing receivers to users quicker than ever! There is also no need to spend time trying to untangle cables at the end of the event.
As the receivers sit flat on the outer ear (and are not inserted into the ear canal), cleaning and sanitising is quick and easy. 
Both the transmitter and receivers have integrated rechargeable batteries for all day operation. The system is stored and recharged in lightweight yet robust charger cases, with retractable handle and wheels for easy transportation.
A wide range of accessories for the system can be found here.
