Mojave Audio MA-37

Technical Grammy Award Winner David Royer’s modern take on a legend – the 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 “Wrecking Crew’ era. Studios such as Capitol Records and Sunset Sound acquired multiples, which are still used today. From Leonard Bernstein and the Columbia Symphony Orchestra and VO legend Mel Blanc (the voice of over 400 characters, from Bugs Bunny to Barney Rubble) though producer Daniel Lanois (U2, Peter Gabriel) and current artists, such as Bon Iver, the C-37a remains a ‘secret weapon’ microphone for those in the know. David states, “Sony took a completely different approach than Neumann and AKG, which made the C-37a a completely different animal”.

The Mojave MA-37 features an EF86 tube, Lundahl transformer and a special capsule hand-built in California. It features a unique mechanical approach, developed by RCA in the 1930s and adapted by Sony, to achieving a choice between cardioid and omnidirectional polar patterns – an adjustable tuned acoustic chamber.
