Right - here goes......
Music room (PC'S) - The teacher has asked if we can find a 'wireless' device - that plugs into the headphone socket of the PC that will transmit the audio to a reciver which is plugged into a Hi-Fi.
i.e. When a child produces a good piece of work you can plug in a (battery powered) 'dongle' type thingy and the whole class can listen via the classroom hifi.
Tried just a set of speakers - but not enough 240v plug sockets in the room. They already have a long lead (H&S kicking up).
