The MA-37 large diaphragm tube condenser microphone from Mojave Audio is a modern take on the legendary Sony C-37a. Known for its high headroom and ability to tame brittle high end, it became a workhorse in the 60’s, especially during the golden age of Hollywood recording. The Mojave MA-37 features an EF86 tube, Lundahl transformer and a special capsule built in California. It features a unique mechanical approach, developed by RCA in the 1930s and adapted by Sony, to achieve a choice between cardioid and omnidirectional polar patterns – an adjustable tuned acoustic chamber. The simple yet elegant circuit design is based around a single-stage tube amplifier. The hi-pass filter controls are located on the power supply, offering three options: at (M), 100Hz (V1) and 200Hz (V2).
