This battery module is recommended when you need to use our small microphones in high SPL situations. The case of this battery module is made of lightweight black ABS plastic.
This will power your microphones with 9 volts of bias power (sometimes called “plug in power”). Most small Electret Condenser microphones will enjoy improved high SPL performance with this higher power, since most portable recorders only provide about 3-5 volts plug in power at the mic input.
A selectable bass roll off (bass reduction) filter is built in which provides seven different bass roll-off frequencies to choose from, with independent switches for each channel. The bass roll off is used when the material to be recorded has excessive bass content and allows the user to adjust the bass response of the mic system accordingly. The selectable frequencies are 16Hz (no bass roll off), 69Hz, 95Hz, 107Hz, 160Hz, 195Hz and 888Hz.
