Condenser Microphone. Your MA-37 was carefully designed and constructed using only the finest materials. The MA-37 microphone is capable of delivering superb performance and, with minimal care, will do so for many years. Your MA-37 was thoroughly tested and given a 24-hour factory burn in prior to shipment.
The MA-37 uses a line fuse for protection. Never replace this fuse with one of a higher current rating. Use only that type which was supplied with the unit. The power supply cord that is supplied with your MA-37 is a standard “business machine”...
Your MA-37 was thoroughly checked and burned-in before leaving the factory. Before using it for the first time, we recommend connecting the MA-37 to its power supply and letting it warm up for at least thirty minutes. Moisture build-up on the capsule or on the other high-impedance components within the microphone can cause random noise or static.
6. Do not expose the microphone to dusty, smokey, or humid environments. 7. Any repairs must be performed by a qualified technician. Other than the EF-86 tube, there are no user serviceable parts in the MA-37. For tube replacement instructions, please contact support@mojaveaudio.com 8.
