A versatile tube mic with interchangeable capsules.

The Mojave Audio MA-100 is a small diaphragm, vacuum-tube condenser microphone with interchangeable cardioid and omnidirectional capsules. Featuring hand-selected 3-micron capsules, high-quality Jensen audio transformers, and military-grade JAN 5840 vacuum tubes, the MA-100 performs at a level reminiscent of some of the best-loved, classic, small-diaphragm tube condenser mics.

The latest in a lineage of successful microphone designs by David Royer, one of an elite group of microphone designers who know that music and sound are inseparable from electronic design. The MA-100's 'cathode follower' design allows use on high SPL instruments, such as drums and guitar amplifiers, as well as the more common applications of small-diaphragm, vacuum tube condenser micd, such as acoustic instruments, cymbals, stereo pairs, and pianos. Each MA-100 microphone, power supply, and cable set is burned in for 24 hours, carefully tested and evaluated, then packaged in its protective case. The MA-100 power supply can be set for either 115v or 230v via an external switch.

Small Diaphragm—Big Sound!
Why choose a small diaphragm microphone? Because small diaphragm microphones offer some distinct advantages over their larger brethren:
•More consistent polar pattern
•Better transient response
•Ease of placement

Why choose an MA-100 Mic from Mojave Audio?
•Extended low-frequency response
•High SPL handling capability—try putting your large-diaphragm mic on a snare drum.
