MA-100 Condenser Microphone
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
Why choose an MA-100?
Extended low-frequency response
High SPL handling capability - try putting your large-diaphragm mic on a snare drum!
