How do we create Silent PA?
Congress Rental has the Infrared Multi-channel Distribution system from Bosch.
The system allows up to 32 channels of audio, speech or music to be transmitted simultaneously to the audience. Each participant carries a receiver and headphone. The channel selected on the receiver corresponds to the desired audio channel.
Transmitter and Radiators
The audio channels are transmitted using our electronics and infrared radiators. Each audio feed is modulated onto a separate infrared channel.
Infra Red Digital Receiver
The user tunes to one of 32 channels using the receiver and headphones. They can then move freely throughout the venue.
