Lavalier Microphone Kit

The F&DM Equipment Checkout Lab releases the Sony ECM-44B Lavalier Microphone in a microphone kit package.

This package includes:

  • Sony ECM-44B Electret Condenser Microphone
  • Lapel Clip
  • Windscreen
  • AA NiMH Rechargeable Battery

Technical Specifications and Settings

The microphone’s diaphragm is extremely sensitive, and will pick-up physical contact with clothes quite easily if not situated carefully. It will also pick-up the force of air, making the mic susceptible to wind noise as well.

The audio cable connecting the microphone to the power module/XLR connection is extremely delicate, and great care should be used to protect it from harm; wheeled chairs in particular.

The ECM-44B Lavaliere Mic is considered a battery-powered microphone; therefore it powers its own signal, and should not be used in conjunction with Phantom-power systems. Engaging the Phantom-power option in conjunction with a battery-power microphone may have particularly harmful effects, such as permanent damage to the connector due to voltage overload. Users should take care to confirm that the proper settings correspond with the microphones they are using accordingly.

Access, Instruction, and Support

The ECM-44B lavaliere microphone is generally available at all course levels, however they are limited in supply. Also, unlike the F&DM Department’s pool of basic cardioid and super-directional microphones, these ECM-44B microphones are not included with an Audio or Video Kit, and must be thereby reserved separately. Given the more limited supply and popularity of these microphones, it is recommended that they be reserved as soon as possible to ensure timely access accordingly.
