Thank you Rob, that's good info about gain requirements. I do not trust the=

You ask, do I need pre-amps. Yes, I want line level to avoid the mic pre's =

Neat find Paul. As you are probably aware, there are very few
battery-powered mics pres with phantom at this price point. 50 dB
gain is on the low side for nature recording-- 60dB is closer to the
desired minimum in my experience. Based on the spec sheet I found,
there are no noise specs supplied and no phantom voltage specified.
Your mics may or may not require higher voltage, even 48 volts. None
of this means you shouldn't give it test. If you order it from
Sweetwater, they'll usually let you return if it it doesn't meet your
needs. Are you sure you need a preamp and not just a portable
phantom power supply? These are available at high (no risk) quality
for $50. Rob D.
