Manufacturer's Description from Mojave Mics

Retro. Futuristic. We are proud to introduce 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 use 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 Royer, who has been a fan of the C-37a for thirty years, has long desired to oer his updated version to the Mojave family – and that time has come. He states, “Sony took a completely different approach than Neumann and AKG, which made the C-37a a completely dierent animal”.

The Mojave MA-37 features an EF86 tube, Lundahl transformer and a special capsule built here 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 pattens – an adjustable tuned acoustic chamber. In keeping with David Royer’s “simple yet elegant” design philosophy, the circuit is based around a single-stage tube amplier. The hi-pass lter controls are located on the power supply, oering three options: at (M), 100Hz (V1) and 200Hz (V2).

The Mojave MA-37 – it sounds great – in a different way!

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.
