The black Sony ECM-77BC is a miniature omnidirectional lavalier microphone designed for professional broadcast, sound reinforcement, and recording applications. The condenser mic element's tiny profile allows it to be easily concealed in performance and broadcast situations.

The omnidirectional polar pattern provides even frequency and sensitivity response at the direct and off-axis sections of the microphone capsule, helping to provide consistent levels, even if the talent isn't speaking directly toward the mic.

The ECM-77 provides a wide frequency response of 40 Hz to 20 kHz for accurate reproduction of speech and vocals and requires 1.1 to 10 VDC power from a compatible wireless transmitter or similar device. A windscreen to reduce wind and breath noise and a tie clip to attach the mic to clothing are included.

Features

4-Pin Sony Hirose Connector

Compatible Transmitters
  • Sony: Works with Sony transmitters equipped with a 4-pin Sony Hirose connector including the DWT-B30 and DWT-B01.
  • Third-Party Devices: The ECM-77 will work with many third-party wireless transmitters and portable audio recorders that are equipped to supply 1.1 to 10 VDC through a 4-pin Sony Hirose connector.

Dependable Performance

Small Size
The ECM-77's capsule is 1/4" in diameter and 1/2" in length, allowing the mic to be used on stage or on camera while remaining inconspicuous.

Headroom for Standard Speech and Vocal Applications

The mic can handle up to 120 dB SPL without distortion—adequate headroom for most presenters, performers, and instructors.

Omnidirectional Polar Pattern

The forgiving omnidirectional polar pattern picks up sound from all around the mic and provides a consistent frequency response, even for off-axis sound. This helps to supply clear, intelligible speech and vocals, even when the talent turns away from the microphone.

Wide Frequency Response

With its 40 Hz to 20 kHz frequency range, the ECM-77 provides accurate and transparent reproduction of speech, vocals, and instruments.
