These systems are ideal for council meetings and conference centres. They have the ability to control from 5 up to 3000 digital microphones and voting receivers. The voting receivers could have either 3 choices (yes, no or not present) or 1 of 5 choices, multi-choice, roll call voting etc. By using a chip card the system can recognise each delegate and by using cameras the system can automatically follow the conversation by showing on a screen who is talking. 2 to 32 simultaneous translations can be achieved.
