MP47

In any audio device, the power supply is a significant contributor to sonic success or failure. In tube microphones this is even more so than anywhere else. The MP47 allows you to realise the full potential of your treasured vintage Neumann U47 or U48 tube mic. Hear your mike as never before.

“The MP47 allows you to realise the full potential of your treasured vintage Neumann U47 or U48.”

The ‘MP47 | 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 MP47 uses a discrete shunt regulator for the anode supply, which doubles as 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.

Stylish, compact and practical, the MP47 fits well on any recording stage.

This week we used the MP1’s with the M50s of my colleague. We were both astonished.

I was thrilled with your power supplies for my Neumann M50's. We used those mics for an upcoming Chandos release of the Kansas City Chorus, and they were stunning.
