Canada

This microphone was one of several acquired by the CBC for use by reporters, announcers and commentators covering the Royal Tour of 1939. These microphones were later used by CBC war correspondents during the Second World War. This is a Canadian-built version of the Western Electric 633A.

Function

Convert sound into an electrical signal that can be amplified, recorded or transmitted over a communication channel.

Technical

The 633A is a dynamic microphone that, when mounted horizontally with the baffle attached over the mouthpiece, provides a degree of directionality well suited for use by a radio announcer. That is, it responds more strongly to sounds coming from the announcer's position than to sounds from other directions. A verticall mounting without the baffle produces a more omnidirectional response.
