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-44B, is the XLR version with power barrel for use as a wired microphone.
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.
Tuned for voice pick-up
The ECM-44's capsule features an emphasis curve and a suitable frequency response for voice pick-up.
The capsule has a diameter of only 8.5mm and is 14.5mm long.
Ready for wired applications
The ECM-44B is the wired version with an XLR output and integral power supply barrel. This version is to be powered internally by battery (LR6 or AA size). A single AA battery will provide several thousand hours of use.
