help Sony ECM-50 FAQ
When was the Sony ECM-50 first released?
Sony identifies the ECM-50 as its first lavalier microphone, released in 1969. Its unusually small capsule subsequently became a familiar sight in broadcasting and television production.
Why was the ECM-50 often visible on old television presenters?
The microphone was frequently clipped prominently to clothing because its cylindrical housing was considered remarkably small in 1969. Its omnidirectional pattern also made placement less critical than with a directional microphone.
Can the Sony ECM-50 plug directly into a modern camera?
Not usually. The ECM-50 was designed to work with an external power unit and professional audio equipment, so connector type and powering must be confirmed before connecting it to a camera or wireless transmitter.
How does the ECM-50 differ from a modern Sony ECM-77 lavalier?
The ECM-77 is considerably smaller and is available in connector variants intended for modern professional wireless systems. The ECM-50 remains attractive mainly for period production, collecting, and its recognizable broadcast appearance.
