Question by: Product code: 70-4084

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.

Question by: Product code: 70-4084

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.

Question by: Product code: 70-4084

Q. Does this pre-amp need a separate power supply?

A. Hi Neil, thanks for your question. Yes this needs a 10-30Vdc supply.
