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.

Versatile performance
The ECM-66B has an extended frequency response and high SPL handling, making it highly versatile.

FEATURES

  • Designed for a wide range of audio sources - The ECM-66B's capsule features an extended frequency response and it can handle high SPL signals.
  • Ready for wired applications - The ECM-66B is the wired microphone version with an XLR output and integral power supply barrel. It can either be powered by the external microphone amp or an internal battery (LR6/AA size).
  • Compact size - The capsule has a diameter of only 10.6mm and is 24mm long, making it easy to conceal.
