Mojave AudioMA-37 Large Diaphragm Tube Condenser Microphone
1/5
Independent shopping perspective
The Korena take
MA-37 is a large-diaphragm tube condenser built around a single-stage EF86 tube amplifier, Lundahl transformer, and California-built capsule. Its mechanically adjusted acoustic chamber selects cardioid or omnidirectional operation instead of using an electronic pattern switch. The design is described as offering high headroom and reducing brittle high frequencies. On its power supply, select flat M, 100 Hz V1, or 200 Hz V2 high-pass settings to tailor the low end. It offers a focused tube-mic signal path with hands-on pattern and filter selection.
Strong match
Who this is for
- Recording setups that need a choice between cardioid and omnidirectional microphone patterns.
- Sessions needing selectable flat, 100 Hz, or 200 Hz high-pass settings.
