It features a slow-ramping filament voltage to extend tube life and full regulation, so the microphones always operate the same regardless of line voltage variations or location; full regulation also means it can safely power only one microphone if needed. Each power supply is calibrated to the microphone system it comes with and is burned in as a full unit. The M 901S dual power supply has two 9-position polar pattern switches, one per microphone, giving nine patterns from omnidirectional to figure-8, including cardioid. Each microphone's pattern is set independently, which makes mid-side and Blumlein recording simple.\u003c\/p\u003e\n\u003ch3 style=\"font-size:17px;font-weight:700;color:#0D1B3E;text-transform:uppercase;letter-spacing:.06em;margin:30px 0 12px;padding:0 0 7px;border-bottom:2px solid #006D77;\"\u003eFC03S locking flight case\u003c\/h3\u003e\n\u003cp style=\"margin:0 0 12px;\"\u003eThe FC03S is a combination locking flight case with a shell made from a blend of hardwoods, wrapped in a premium travel fabric, with dual combination locks and nickel trim.
