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 environmentsTwo-way Powering
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) operationBuilt-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.| Capsule Type | Mono Electret Condenser |
