29 jan 1954 ano - EMT introduces plate reverb

Descrição:

In this electro-mechanical device, an audio
signal is sent to a transducer (rather like a loudspeaker without the paper cone) attached to a large metal plate, which is suspended on elastic mounts. Transducers on the plate pick up the modified sound and convert it back into an electronic signal.
