Greetings from Norfolk, UK.

Before anybody can sensibly answer,the following would be very useful

What type of mic.?
What output level required ?
What frequency response required ?
What skill level of builder ?
And MOST IMPORTANT, what funds available ?

The very best mic preamp, taken from INA103's datasheet.

I use it in broadcasting equipment and it has very good specs.

To make a +48V phantom PSU, just check here or follow this link

Did it helped?
