Under my administration was a computer class in high school with a good projector.
One thing — audio equipment there are no plans.
But computer monitors are a pair of speakers, the Machico placed around the perimeter of the class.
One idea is to configure the broadcast channels from the host computer (for example to drive through a stream only right channel and only the left, and ideally 5 or 7) to each PC played the role of a space diversity dynamics.
Possible problems with the implementation of the idea just want to try.
Are only interested in how to broadcast multiple channels.
