MA-301fet Condenser Microphone
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 resis-tors, the MA-301fet performs at a level reminiscent of some of the best loved classic condenser microphones. Each MA-301fet microphone iscarefully tested and evaluated, then packaged in its protective casewith a professional grade shock mount.
