SONY ECM-44BPT Omni-Directional Lapel Microphone (Without Connector Pigtail)
Sony has produced over five million professional ECM (Electret Condenser Microphones) microphones and the ECM-44 is the affordable, general voice model. It provides good sound quality and is widely used in business presentation systems and TV production. The ECM-44 is available in four versions, featuring different connector types. This model, ECM-44BPT, does not feature an XLR connection. The unterminated cable allows users to custom wire connectors to individual need.
Convenient to use
The ECM-44 is an affordable alternative to the traditional hand held microphone and being 'hands free' it allows the presenter to concentrate on her/his performance
Either 'in front of camera' or at a business presentation the ECM-44 creates a professional and tidy image.
Easy to use
It can often be difficult to achieve good quality voice pick-up but the ECM-44 can help get good results. The microphone's capsule is designed for general voice pick-up with a mid-frequency emphasis characteristic and a suitable frequency response.
