The preamplifier is intended for use with dynamic (moving coil–MC) microphones with an impedance up to 200 Ω and balanced terminals. The preamplifier is intended for use with dynamic (moving coil–MC) ...

Most PC “mic” inputs are pretty average for noise and distortion, and they’re usually mono. Plus, they can’t properly take balanced, pro microphones that often need 48-V phantom power. This ...

We published a design for a stereo microphone preamplifier with balanced inputs and a phantom power supply. The heart of this circuit was a special Analog Devices IC, the SSM2017. Unfortunately, this ...

Over the years I’ve become a student of mic preamp design, building and modifying several along the way and learning a little more each time. Usually, I worked from a kit or published set of plans.
