Grimm Audio MP1RC Power Supply with Polar-Pattern Control for Tube Microphone

Even if the power supply on your vintage microphone is still functioning, the MP1RC's stable power and exceptionally low noise floor can give you significantly improved sonic results; and voltage settings are customized at the factory for optimal performance with your microphone model. The unit offers discrete voltage regulators, a shunt regulator for the anode supply, and a high-precision series one for the filament supply. The anode supply offers a noise floor as low as -100 dBV, which, on average, is 20 dB better than existing supplies, while the shunt design turns the regulator into an active decoupling device, eliminating electrolytics.

Voltages for the MP1RC are factory-set to optimize performance. Please call us when ordering to customize the settings for your microphone.
