MA-100 Condenser Microphone

Mojave Microphones

The MA-100 is a small diaphragm, vacuum tube condenser microphone with interchangeable cardioid and omnidirectional capsules. The latest in a lineage of successful microphone designs by David Royer, 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 a small diaphragm, vacuum tube condenser microphone, such as acoustic instruments, cymbals, stereo pairs and pianos.

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 microphones. The MA-100 power supply can be set for either 115v or 230v via an external switch. 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.

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

    Russ Long - Pro Audio Review
  • "Having a mic this versatile come with two capsules for less than $1k ($795) is a steal. Mojave's second outing is a must-hear."
    Kevin Becka - Mix
  • "At around $795.00 each, the MA100 is an affordable, great sounding solid studio microphone that will greatly enhance all your recording needs. It is the biggest sounding small diaphragm condenser I've had the pleasure to listen to. I can't wait to hear what Mojave comes up with next! "
    Craig Schumacher - TapeOp

  • "These MA-100s are the business! Blew away the 'standard'
    small-diaphragm mics I've used before. The players were all floored, as was my assistant."
