Sony ECM-673 Shotgun Microphone

Overview
The ECM-673 microphone is known for its superb sound quality, offering a sensitivity of -36 dB and a low inherent-noise level of less than 17 dB SPL. This allows for clear voice pickup, even in noisy environments. Additionally, the microphone has a flat-and-wide frequency response of 40 Hz to 20 kHz, providing smooth and natural sound reproduction.

The compact and lightweight design of the ECM-673 makes it highly versatile and suitable for use with compact camcorders. It measures only 200 mm in length and weighs just 135 g, maintaining good balance when mounted on a camera. The microphone is also built to withstand harsh environments, thanks to its vibration-resistant mechanism. It also features a built-in low-cut filter for reducing unwanted ambient noise. The ECM-673 is a short shotgun, electret condenser-type microphone that delivers excellent sound performance at an affordable price. It is also tailored for use with HDV type camcorders for compatibility.

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 working 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 200 mm (7 7/8 inches) in length, and weighs just 135 g (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.
