Grimm’ re-writes the book on tube mic supplies. Drawing from the extensive expertise gained designing the supplies used in the AD1 and CC1 products, the MP1 uses discrete voltage regulators, a shunt regulator for the anode supply and a high precision series one for the filament supply. The anode supply offers noise as low as -100 dBV (in average 20 dB better than existing supplies) and the ‘shunt’ design turns the regulator into an active decoupling device, eliminating electrolytics.
 
Voltages are factory pre-set to match the customer’s microphone specs.
Stylish, compact and practical, the MP1 fits well on any recording stage.
