I'm doing some field recordings with electret microphones. The manufacturer says they require a voltage between 2 and 10 volts. My Zoom H2N recorder delivers something around 2 to 3 volts I believe, which is at the lower range of the operation voltage range.
How does a higher voltage like 9 volts affect the recording behavior of the mic? Does a higher voltage enhance the signal-to-noise ratio (reducing it's self-noise) and increase the sensitivity for quiet sounds in nature?
I've heard that a higher voltage would make the mic more tolerant towards loud sounds but less sensitive for quiet sounds, so I'm a bit confused wether or not I should get a preamp.
