Cardioid Pencil Condenser Microphone

The Equation Audio CMI.103 is a small-diaphragm short pencil condenser.

Switchable 10dB pad and low rolloff are available on the metal body.

Sound On Sound 2008
I thought the overheads sounded pretty well balanced with no pad or low-cut filter switched in, and pulling up their fader really brought the kit sound to life, although a little ‘air’ EQ at 12kHz helped to lift the cymbals. More exotic mics would no doubt give a better-focused sound, but overall I have to say that I liked what I was hearing.

Equation Audio has published very little information about their China manufactured Alpha Series.

The Equation Audio CMI.103 is also known as: CMI-103.
