Uni-directional (Super Cardiod) Electret Condenser Shotgun Microphone, Phantom Powered
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.
Offering high-sensitivity, low-noise characteristics and flat-and-wide frequency response
in a compact and lightweight design, the ECM-673 is well-suited for use with Sony professional camcorders,
such as the HDV Series, DVCAM Series, and XDCAM Series.
With its high performance, affordable price, and great versatility, the ECM-673 microphone
is an ideal choice for a range of sound-acquisition applications.
FEATURES
Superb Sound Quality
The ECM-673 offers an excellent sensitivity of -36 dB (0 dB=1 V/Pa) and a low inherent-noise
level of less than 17 dB SPL. This allows the microphone to be used for clear voice pickup,
even in noisy environments.
Flat-and-wide Frequency Response
The ECM-673 microphone has a flat-and-wide frequency response (40 Hz to 20 kHz)
and delivers extremely smooth and natural sound reproduction.
Compact and Lightweight Design
The ECM-673 has been designed as a highly directional, compact, and lightweight
short shotgun microphone. It measures only 7 7/8 inches in length, and weighs just 4.76 oz,
maintaining good balance even when mounted on compact camcorders.
High Durability and Reliability
The vibration-resistant mechanism of the ECM-673 offers high durability and reliability,
making it suitable for the harsh environments that can be encountered in field sound-acquisition.
Built-in Low-cut Filter
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.
