MA-50

A transformerless FET condenser with premium clarity

The challenge? Create a transformerless microphone circuit without
the inherent problems found in transformerless microphones. TECHNICAL
GRAMMY® Award-winning microphone designer David Royer has
created a thoroughly modern microphone that rises to that challenge:
the new MA-50BLK. Designed to produce the clarity and realism that
Mojave microphones are known for, at an entry level price, the MA-50BLK
outperforms well-known transformerless mics costing many times
more.
