A clean microphone preamp for recording

The radio-active topic

Postby fredv » Wed May 30, 2007 12:00 am

Good afternoon, everyone. I'm new to the forum and hope to learn some interesting things from all of you. I subscribed to Elektor in magazine form in the 1970s, (yes, that's right), and recently found a renewed interest and rejoined after 25 years.

One thing I'm interested in finding is a nice preamp circuit for a microphone. I would like to take balanced, 600 or 150 ohm, -55 dB and bring it up to -10 to 0 dB, 10k-ohm. Some of the other criteria I need is; very low noise, like you would find in a Soundcraft or Mackie mixer. I would also prefer a DIP style chip.

Anyone found any interesting chips that will meet the criteria, and available in both the UK and US?
