With a form and tone well suited for event video shoots, indie film production, TV and documentary shooting, court room depositions, and more, the Sony ECM-674 shotgun microphone offers strong, clean output signal for recording with camcorders, multitrack field recorders, and portable audio recorders.

The ECM-674 features a supercardioid polar pattern for excellent directivity and minimal noise at the off-axis sections of the capsule, resulting in intelligible voice pickup even in noisy environments. The microphone's wide, flat frequency response yields smooth, accurate signal reproduction with crisp detail and minimal coloration.

The ECM-674 can be powered with a single AA battery (available separately) or 40 to 52 VDC phantom power, making it compatible with a variety of consumer and professional devices. It includes microphone spacers and a mic holder to accommodate camera-mount and stand-mount configurations.


Lightweight Design

The ECM-674 has been designed as a highly directional and lightweight shotgun microphone, measuring 10.6" in length and weighing 6.5 ounces to ensure good balance even when mounted on compact camcorders.

Smooth Frequency Response

With its flat and wide frequency response of 40 Hz to 20 kHz, the ECM-674 provides sound reproduction that is smooth and natural.

High Sensitivity

The ECM-674 offers an excellent sensitivity of -36 dB and low self-noise level of less than 17 dB SPL, allowing the microphone to be used for clear voice capture even in noisy environments.

Onboard Low-Cut Filter

The onboard two-position (M, V) low-cut switch provides users with a simple method of reducing the effects of undesired ambient noise such as rumble.

AA Battery or Phantom Powered

The two-way powering capability allows the ECM-674 to be driven by 40 to 52 VDC phantom power or a single AA battery, making it suitable for both camcorder mounting and many other sound-gathering applications.

Built-In Battery Liquid Leakage Protection Circuit

Considering that old batteries can leak and damage the equipment they power, the ECM-674 prevents this by continually detecting the output voltage of the battery and shutting off the power supplied to the electric circuit whenever the voltage drops beneath a certain threshold.

Included Accessories

The ECM-674 is supplied with a windscreen that attenuates wind noise by approximately 5 dB, a short XLR cable, a microphone holder (for use on a mic stand), two stand adapters, a molded-type microphone spacer, and a sheet-type microphone spacer.
