CardioidMojave Audio MA-201 FET

Cardioid Condenser Microphone

The MA-201 FET is David Royer’s first FET mic under the Mojave Audio name. It features a fixed-cardioid, 3-micron large diaphragm capsule, a Jensen output transformer, and “ultra clean” circuitry in between. It is billed as a solid-state version of the MA-200.

The PCB has very few components on it. There is no DC converter; the capsule is polarized at about 45V. There is no pad nor filter.

[The MA-201FET] has more of a presence peak [than the MA-200], so some of our rock drummers are preferring it for drum overheads over the 200, which a little more of a pretty, open, airy sound, U-67-ish sound. The 201Fet has more of a presence pump to it. It works great on bass guitar amps. I call it the “poor man’s 47FET.” It works great on kick-drum; use it with a dynamic microphone on the kick drum and it works wonderfully.

It ships with a suspension shockmount in an aluminum flight case, and carries a 2-year warranty.

Pro Audio Review, 2009-03

Room miking revealed the wide cardioid pattern of the MA-201; it was nearly as open as my omnis…

After spending several months with the MA-201 FET, I’ve found that during the microphone selection process, it is applicable to think of the MA-200 as a modern-day Neumann U 67 and the MA-201 as a modern day Neumann U 47 FET.

Electronic Musician, 2009-03

One standout application for the MA-201s was on piano… The MA-201s served well spread out across the soundboard, close to the strings for a bright, present, attacky sound… They also sounded great backed off a bit in XY to get a roomier, larger sound for use in a sparser song.

The Mojave Audio MA-201 FET is also known as: MA201.

The mic was released in 2008.
