Short Shotgun Electret Condenser Microphone

The ECM-673 is a short shotgun, electret condenser-type microphone, which delivers excellent sound performance in field and studio production applications at an affordable price.

The ECM-673 offers an excellent sensitivity and a low inherent-noise level. It has a flat-and-wide frequency response and delivers extremely smooth and natural sound reproduction.

The built-in two-position (M, V) low-cut switch on the ECM-673 provides a simple method of reducing the effects of unwanted ambient noise.
