Sony ECM-674 Shotgun Condenser

Sony ECM-674 is an affordable shotgun-type electret condenser microphone, which delivers excellent sound performance in field and studio productions. Offering high-sensitivity, low-noise characteristics and flat-and-wide frequency response in a compact and lightweight design. The ECM-674 is well-suited for use with Sony camcorders such as the HDV™ Series, DVCAM™ Series, and XDCAM™ Series. In addition, its two-way powering feature allows for both microphone power operation and battery operation. With its high performance, affordable price, and great versatility, the ECM-674 microphone is an ideal choice for a range of sound-acquisition applications.

Features

The ECM-674 offers an excellent sensitivity of -36 dB (0 dB=1 V/Pa.) and low inherent-noise level of less than 19 dB SPL. This allows the microphone to be used for clear voice pick-up even in noisy environments.

The ECM-674 microphone has a flat and-wide frequency response (60 Hz to 18 kHz) and provides sound reproduction that is extremely smooth and natural.

The ECM-674 has been designed as a highly directional compact and lightweight shotgun microphone. It measures only 10 5/8 inches in length and weighs just 7 oz, maintaining good balance even when mounted on compact camcorders.
