Multichannel receiver to enable three Conversor Pro microphone/transmitters to be used simultaneously in the same room for transmission to one or more receivers in the same room. The unit is battery powered and portable. In normal operation an FM system can only have one microphone/transmitter for each frequency switched on at the same time as the broadcast signals cancel each other out Conversor Pro multichannel receiver solves this problem by using a combination of microphone/transmitters and receivers programmed to different frequencies. The signals of the transmitters are then mixed and rebroadcast to a receiver or receivers on an independent fourth frequency channel. This system can be used as a single user system for a barrister or attorney in a courtroom.
