GRAMPIAN TYPE MCR MICROPHONE, 1930's

Early Moving Coil Microphone used with Public Address systems.

Your comments:

  • I have one of these and was surprised to see one in an air museum wired to a Bomber Command transmitter used in WWII.
    Not sure if this was a genuine alliance?
    However I have regularly seen them on films of that era used as a PA mike and even used by singers of big bands.
    Unfortunately on TV dramas I've seen them used round the other way, being spoken into from the back; shame on the sound man!

  • I have one of these and although the device appears rudimentary, the design of a cone shaped receptor, attached to the coil, is mounted so that it sits between the front apperture and the side appertures. This makes the microphone behave as a velocity microphone and is quite directional.
