Recording and Measurement Microphones. Recording and Measurement MicrophonesRod Elliott (ESP) PCBs for the discrete mic preamp and a complete housing are available - click on the image for details (New PCB available) Introduction The purpose of this article and small group of projects is firstly to introduce the electret microphone into the ESP projects lineup, and secondly to allow the reader to build a microphone that although uncalibrated, can be used to great effect as a measurement mic with any loudspeaker project, or for very high quality recordings.
The P93 microphone amplifier is a discrete fully Class-A transformerless design, and offers high performance at comparatively low cost. Traditionally, measurement microphones are calibrated, so that the exact output level for a given SPL is known, and so that the frequency response is predictable and accurate.
