Q. It says 10-30v for power. Do you think I would get away with a 9v battery?
A. Hi Mike, thank you for your question. This does really require a stabilised power supply so the 9V battery possibly would not last long anyway. A small 12V battery may be a better option like 18-1146 or 18-0605.

Q. Hi there, what input impedance is this suitable for? Many thanks
A. Hi Lewis, thank you for your question. The input impedance is high, so we would suggest microphones with 1-2K impedance.

Q. Does this pre-amp need a separate power supply?
A. Hi Neil, thanks for your question. Yes this needs a 10-30Vdc supply.
