Audio/video switching unit

As more and more audiovisual equipment is cheerfully stacked up in your living room, connecting it all is bound to become a problem sooner or later. What do we want? A number of audio and video signals have to switched between different equipment: for instance, we want the pictures produced by the hi-fi video recorder to be visible on two TV sets at the same time, while the recorder should still allow us to choose between recording TV sound or a signal from 'the stereo'. All this is possible with the electronic switch discussed here, wh ich can be given as many inputs as you think necessary.
