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.
