Sony ECM77B

The Sony ECM-66B is a professional miniature cardioid lavalier microphone crafted for superior audio pickup in live performance, presentation, and broadcast scenarios. Known for its compact design and high audio fidelity, the ECM-66B excels in environments where clarity and discretion are essential. Its cardioid pickup pattern ensures targeted audio capture while minimizing background noise, making it a reliable choice for use in noisy environments or on stage.

This model includes an integrated power supply barrel and comes terminated with an XLR connector, supporting both internal battery power and 48V phantom power for maximum flexibility. With its small capsule (only 10.6 mm in diameter and 24.2 mm long), the ECM-66B can be easily concealed in clothing, making it ideal for interviews and theatrical use. It boasts an extended frequency response from 70 Hz to 14 kHz, high SPL handling (up to 130 dB), and a robust dynamic range of 101 dB or more, allowing it to accurately capture both subtle and powerful sound sources.

The ECM-66B is designed with the end user in mind. It features a 3-meter cable and includes multiple accessories such as windscreen, vertical and horizontal tie clips, and a carrying case for on-the-go convenience. Its cardioid pattern also helps to reduce feedback, a common issue in live sound applications. Whether you're equipping a presenter, a performer, or a corporate speaker, this lavalier microphone delivers clear, consistent sound with minimal fuss.
