| 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 HDVTM Series, DVCAMTM Series, and XDCAMTM 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. Superb Sound Quality 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. Flat-and-wide Frequency Response 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. Compact and Lightweight Design 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. Specifications
