SONY ECM-66B Miniature Cardioid Directional Lapel Electret Condenser Microphone
The ECM-66B miniature, lapel microphone is suitable for voice and musical instrument pick-up in noisy environments. The cardioid polar response allows the microphone to be positioned for picking up the sound source while rejecting background noises. It is supplied with a integral power barrel and it is terminated with an XLR connector.
Hands Free microphone
As a lapel microphone, the ECM-66B is an alternative to the traditional hand held microphone and being 'hands free' it allows the presenter to concentrate on her/his performance.
Simple to use in public address systems.
As a cardioid polar response microphone, the ECM-66B can help to reduce the potential problem of microphone 'howl round'. The alternative omni-directional microphones are more prone to creating audio feedback loops.
The ECM-66B has an extended frequency response and high SPL handling, making it highly versatile.
