Large Diaphragm Condensers
The MA-301fet is a multi-pattern large diaphragm, solid-state condenser microphone. Based upon the popular MA-201fet designed by David Royer, the MA-301fet adds a 3-posistion pickup pattern selector, a15dB pad and a switchable bass roll-off.
Utilizing a 3-micron gold-sputtered capsule, high-quality Jensen audio
transformer, military-grade FET and custom designed low-noise resistors, the MA-301fet performs at a level reminiscent of some of the best
loved classic condenser microphones. Each MA-301fet microphone is
carefully tested and evaluated, then packaged in its protective case
with a professional grade shockmount.
