Tourtalk TT 40-AD1MH audio description system

An audio description system is used to describe an event to individuals (often blind or partially sighted). The system is perfect for the performing arts such as theatre or dance or at sporting events. The system can also be used for silent conferences or as a radio aid system to assist people that are hard-of-hearing.

The transmitter features an integrated microphone, microphone socket (to connect the headband microphone), and microphone mute switch. An aux-in socket to enable the connection of a smartphone is also provided.

The describer can whisper into the sensitive headband microphone so not to disturb people in the vicinity. The describer can add additional commentary of the production e.g. describing body language, expressions and movements. This gives the system users more information about the things they might not be able to see, enabling them to visualise the scene and keep up with the action.

The listener wears the headphones connected to the receiver and simply adjusts their volume to a comfortable level. The Tourtalk system can be used very discreetly without disturbing the surrounding seats.

Both the transmitter and receiver have been designed to be very easy to use. Each unit features a channel lock function, which stops the user accidently changing the channel, and a lanyard so the user doesn’t have to constantly hold it during an event.

As the system is completely wireless, it can be operated indoors or outdoors and requires no installation.

This Tourtalk TT 40 audio description system is also ideal for one-to-one instructing/tutoring and hearing support.
