RELIGIOUS MATTER BROADCASTING

All over the world, AGBE transmitters are used to broadcast the religious content of a celebration (mass, wedding, funeral) either inside the church building or outside. With the RF power of the transmitter lowered to cover inside the church area, hearing impaired people with the help of their own portable FM receiver are able to listen to the content of the celebration with crystal clear sound without suffering from natural reverberation and echoes in the hall. Numerous hearing impaired

people are going back to church due to the new concept. When the transmitter is installed to broadcast outside the building, people that cannot attend the celebration are able to pickup the signal in their home with their FM receiver and participate to the celebration.
