Short Shotgun 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.
  • Superb sound quality
  • Low inherent-noise level of less than 17 dB SPL
  • Flat-and-wide frequency response (40 Hz to 20 kHz)
  • Compact and lightweight design: 7 7/8 inches in length and 4.76 oz weight
  • High durability and reliability
  • Built-in low-cut filter switch (M, V) for reducing of undesired ambient nose
Feature Benefit
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.
