ECM-674
Affordable shotgun Electret condenser
microphone
The ECM-674 is an affordable shotgun-type electret
condenser microphone, which delivers excellent sound
performance in field and studio productions.
Benefits
This product comes with PrimeSupport – fast, hasslefree repairs and a helpline offering expert technical
advice. Which gives you the peace of mind that Sony
is looking after your equipment, and your business.
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
Features
Two-way Powering
Superb Sound Quality
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
A two-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
Compact and Lightweight Design
Built-in Battery Liquid Leakage Protection Circuit
Flat-and-wide Frequency Response
The ECM-674 has been designed as a highly directional compact and lightweight shotgun microphone. It
measures only 268 mm (10 5/8 inches) in length and
weighs just 185 g (6.5 oz), maintaining good balance
even when mounted on compact camcorders.
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.
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.
