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.

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
• Custom designed low-noise resistors
• Ultra clean signal path

Recommended Applications:

• Vocals
• Voice Over and Broadcast
• High SPL sources, such as Kick Drums and Bass Guitar Amps
• Electric Guitar
• Piano
• Drum Overheads, Drum Rooms
