ECM-678 (ECM678)

Shotgun Electret condenser microphone

Where to buy

Overview

For superior sound quality, chose the ECM-678. Equipped with a newly developed microphone capsule, it delivers superior sensitivity of -28 dB (0dB=1V/Pa) and extremely low inherent noise of less than 16 dB SPL.
This microphone balances the need for a compact size with its ability to deliver excellent performance. The result is a highly directional microphone that is only 250 mm in length.
