Multi-Pattern Condenser Microphone

The CM402 is an unusual large-diaphragm multipattern FET condenser microphone built by hand by the designer, Jörgen Thuresson, in Sweden.

The most remarkable aspect of the mic is its physical design, in which the capsule and amplifier electronics together float within a metal-mesh cylinder that is surrounded by an exoskeletal cage. This approach minimizes the number of reflective surfaces near the capsule, thereby reducing sonic coloration. Users confirm that the mic’s response is “accurate” rather than “colored.”

It was reportedly designed for acoustic instrument miking.

The amplifier circuit is a low-noise design, presumably transformerless, rated at 7dBA. Its output impedance is a very low 20Ω, among the lowest we’ve seen.

The capsule is an edge-terminated design built by Thuresson. It has dual diaphragms, and supports nine pickup patterns via the rotary switch on the underside of the microphone.

The mic ships with a shockmount and an elastic suspension mount, in a Pelican “Peli-Case” (a watertight, impact-resistant plastic suitcase). The CM402 can be purchased singly or in pairs.

Few other details about the microphone are available; we will update this profile as we are able.
