Mojave MA301-FET Specifications

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 selec-
tor, 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 is
carefully tested and evaluated, then packaged in its protective case
with a professional grade shockmount.

Features:

• Multi-pattern: Cardioid, Omnidiectional, Figure-eight (Bi-directional)

• Switchable 15dB pad

• Switchable Bass Roll-off

• Hand-selected 3-micron 1” capsule

• Jensen audio transformer

• Military-grade FET
