Designed specifically for recording meetings, the ECMF8 from Sony is an inexpensive electret condenser microphone with a high-quality output and a small, inconspicuous design.
As a tabletop omni-directional microphone, the ECMF8 picks up sound from all directions, ensuring that speech is easily discernable, even in multiple sound source environments. As a boundary microphone, the ECMF8 is able to offer a flatter frequency response than many other microphones by reducing frequency distorting reflections, providing a low-noise signal even when the microphone is at a distance from the sound source. A frequency response of 50 to 12,000 Hz captures the most important speech frequencies, while a -51 (+/-4 dBm) effective output level delivers a strong signal to the recording device. Output impedence is 1.6 kohms (+/- 30%, unbalanced).
The ECMF8 operates on Sony's CR2025 lithium battery, which has a life of approximately 100 hours. The mini plug connects directly to most portable recorders, while its L-shape helps ensure that it doesn't come disconnected during use. Small and unobtrusive, the ECMF8 weighs just 0.88 ounces (including battery and cord) while its 3.3 foot long cord lets you position the mic a reasonable distance from your recording device. The ECMF8 also comes backed with a 90 day limited warranty on parts and labor.
