Manufacturer's Description from Mojave Mics

The MA-100SP is a matched pair of MA-100 small-diaphragm, vacuum tube condenser microphones with interchangeable cardioid and omnidirectional capsules and a dual power supply. Packaged in a single carrying case, the MA-100SP provides professional recording engineers with a convenient, easy to set up system for stereo recording applications.

From a linage of successful microphone designs by David Royer, the MA-100SP's cathode follower circuitry provides ample headroom for high SPL applications such as drums and guitar amplifiers. It also excels at the more common applications for small diaphragm, vacuum tube condenser microphones such as acoustic instruments, cymbals, stereo pairs and pianos.

Featuring hand selected, 3-micron cardioid and omni capsules, high quality Jensen audio transformers and military-grade JAN 5840 vacuum tubes, the MA-100SP performs at a level reminiscent of some of the best loved classic small-diaphragm tube condenser microphones. The MA-100SP's power supply can be set for either 110-120 VAC or 220-240 VAC via an external switch. The complete MA-100SP system is burned in for 24 hours, carefully tested and evaluated, then packaged in a protective carrying 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

Why choose an MA-100SP?

  • Extended low-frequency response
  • High SPL handling capability - try putting your large-diaphragm mic on a snare drum!

Features:

  • Interchangeable cardioid and omnidirectional capsules
  • Hand-selected 3-micron capsules
  • Jensen audio transformer
  • Military grade JAN 5840 vacuum tube
  • External switchable power supply voltage
  • Ultra clean signal path
  • High SPL handling capability

Recommended applications:

  • Acoustic Instruments
  • Drums
  • Guitar Amplifiers
  • Piano
  • Stereo Pairs (X/Y, MS, etc.)
  • Decca Tree
  • Orchestral Recording
  • Choral Recording
  • Voice-overs and Broadcast
  • Percussion

About Manufacturer

David Royer started Mojave Audio in 1985 in the garage of his house. The location was Fullerton, California, and Mojave Audio was a one-man, custom pro audio gear shop. David is best known for his ribbon microphone designs with Royer Labs, but he originally started out designing and building vacuum tube microphones, mic pre's and compressors for engineers in the Los Angeles area. Since the mid 1990's, Davidýs custom Mojave products have been used on a number of well-known recordings and have achieved legendary status among a small circle of high-end engineers. With the launching of Mojave Audio, we are able to bring David's non-ribbon designs to the world.
