    It would look like a little box with line-in and line-out sockets and a 5V input (or whatever is need to start the Beolab AND power the box circuitry.

    Inside there will be a relay or something similar that would be triggered by the amplified Line-in signal (sound). The relay would have an auto hold loop with some sort of timing circuitry (I.E it would stick for “some” time when no sound is present and then open).

    Output of the relay will trigger or not the 5V to the Beolab.

    Now, Please note that I’m totally ignorant of how it could impact sound (since we’re playing with the main audio feed, but as far as I remember my electronic classes, this is not NASA technology here.
