beyerdynamic Unite Interpretation System at Mahatma Mandir, India

Two access points replace 30 infrared transmitters at an international event in India

The new beyerdynamic Unite digital wireless communication system was installed with only two access points into the ceiling of the Mahatma Mandir Convention and Exhibition Centre in Gandhinagar, India, and used to transmit eight languages in the 6,000m² congress hall for the international Vibrant Gujarat Global Summit 2019. Here, Unite replaces an infrared system comprising 30 infrared transmitters.

The requirements

The 6,000m² (100x60m) congress hall in the Mahatma Mandir Convention & Exhibition Centre, which holds up to 6,000 people, was to be equipped with new interpreter systems. The existing system of 30 infrared transmitters was to be replaced and there was to be no interference with UHF, WiFi and LED screens.

The solution

Only two Unite AP4 access points had to be installed, synchronised and connected to the Dante audio network. “And the second access point was required only because eight languages were to be transmitted – otherwise, one access point would have sufficed”, says Ajay Parwaney, Director of Pyramid Technologies, the company which implemented the project. One access point can transmit up to four languages. A total of eight access points can by synchronised in a network, meaning that 32 channels can be broadcast simultaneously. There are 1,000 Unite RP beltpack receivers available for participants. They can use the receiver to select the channel with the required language. The DECT system is reliable thanks to its high operating range, long operating time, noiseless digital transmission and automatic frequency management. With the highest AES 256 bit encryption standard, this digital system is also tap-proof. The system can be easily monitored, updated and configured via the Unite cockpit charging technology.


beyerdynamic Unite is an excellent alternative to infrared interpreter systems. With respect to rental, the multi-functional system also requires considerably reduced planning effort, storage and transport costs, and on-site installation time. Unite additionally offers vastly better audio quality, a considerably higher range and additional individual encryption options for maximum security.
