"Controlled reluctance" microphone.
Shure statement from 06/03/2001:
This microphone was an OEM (Original Equipment Manufacturer) model. We made the microphone for another manufacturer. Information on OEM microphones is sketchy.
The CR81 was a Controlled Magnetic, high-impedance (14 kohm) model, light brown in color and made for Revere (Camera), the tape recorder manufacturer.Das Shure CR-81 war anfangs ausgerüstet mit dem "Black Label"-Element, später mit dem "White Label".
Das Gehäuse aus Zink-Druckguss ist identisch mit dem des Shure 510, das erstmals im Katalog von 1949 vorgestellt wurde.
