I have breadboarded this mic design:
http://www.mp3forkidz.com/mic/phantxy.html
It uses the linkwitz mod on the capsule so that the internal FET works as a souce follower, this allows the capsule to work without distortion right up to 134dB. However, when I connect this to my mixer, it can only take much lower sound levels as the mixer itself overdrives long before that output level (as there is no pad on the mixer). What I wonder is if there is a way to integrate a 20dB (or just a significant reduction) into the mic design itself? Many existing condensers have pads built in for this reason. I just can't figure out how, or if it is possible to do on this design, would resistors in series with the 1uF caps work, or will that upset the cutoff frequency of the design?
