An early picture, taken on the 13th of May, 1958, looking through the window of Room 15 towards Rooms 13 and 14. The room on this side is the recording area, complete with microphone and actor. In the distance there's Desmond Briscoe with a tape loop, with a Motosacoche tape machine beyond him, 'Dickie' Bird the engineer, preparing to record the next sequence, and producer Donald McWhinnie, in charge, standing in front of a Ferrograph recorder. Daphne Oram is at the controls of the 'Albert Hall' mixer, on top of which there are a pair of Programme Effects Units (PEUs), which were very effectve top-cut/bottom-cut equalisers. Note the flowers on the loudspeaker.
