Sony ECM-674 Electret Condenser Short Shotgun Microphone

The Sony ECM-674 is a shotgun-type electret condenser microphone which delivers excellent sound performance in both field and studio productions. It features superb sound quality, 2-way powering options, and automatic battery leak prevention.

Key Features: Sony ECM-674 Electret Condenser Short Shotgun Microphone

• Superb sound quality
  The ECM-674 offers an excellent sensitivity of -36 dB (0 dB=1 V/Pa.) and low inherent-noise level of less than 17 dB SPL. This allows the microphone to be used for clear voice pick-up, even in noisy environments
• 2-way powering
  Its 2-way powering capability allows the ECM-674 to be driven by microphone power or batteries, making it suitable for both camcorder mounting and many other sound-gathering applications. Internal: AA-size battery operation. External: DC (40 to 52 V) operation
• Built-in battery liquid leakage protection circuit
  In general, old batteries can leak and damage the equipment they are used in. 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
• Flat-and-wide Frequency Response
  The ECM-674 microphone has a flat-and-wide frequency response (40 Hz to 20 kHz) and provides sound reproduction that is extremely smooth and natural
• Compact and Lightweight Design
  The ECM-674 has been designed as a highly directional compact and lightweight shotgun microphone. It measures only 268 mm (10.6") in length and weighs just 185 g (6.5 oz), maintaining good balance even when mounted on compact camcorders
• Built-in Low Cut Filter
  The built-in two-position (M, V) low-cut switch provides users with a simple method of reducing the effects of undesired ambient noise
