    I need help with the design of a circuit board along with parts sourcing.

    I need to make several single channel Microphone preamps with 48 volt phantom power inexpensively.

    I would like to work with someone to map the circuit board for production.

    Pre Amp is for semiprofessional audio use (XLR input - Line Level output)

    Help needed fast.

    Thank you

    Steven

    I need help with your request.

    Physical size limits on pc board?

    Power availability / requirements? Batteries/AC/DC/unipolar/bipolar/clean/dirty?

    Location? Inside a mixing console, stand-alone at a truck rally, oceanfront - ?

    Several channels on on board, or several single-channel boards?

    Equalization / bandwidth / rolloffs?

    This is all great everyone though I'm actually needing help designing the board with components. I'm willing to pay for the assistance. What I need is to possibly speak with someone here and go over exactly what I'm needing for a finished product. Let me know if your interested.

    Thank you
