Grace Design m801mk2 Microphone Preamp

High-fidelity eight-channel microphone preamplifier
MFR# m801mk2

Product Description

Slapping an “analog warmth” plug-in on every track can only get you so far. Capturing rich, open, musical performances as they happen requires analog hardware, a good set of ears, and above all - it requires Grace Design. The Grace Design m801mk2 Microphone Preamp introduces a number of improvements upon the original Model 801 from 1994 — yet still delivers Grace’s signature sonic quality and reliability.


The m801mk2 Microphone Preamp utilizes custom-designed amplifier circuitry that expands upon the features of the original. Don’t worry, the m801mk2 still includes a fully differential signal path, and Ribbon Mic mode for use with low output ribbon microphones.

The m801mk2 significantly improves noise performance at low gains, allowing you to capture even the most delicate of moments with fewer distractions. Similarly, the m801mk2 improves RFI/EMI immunity for more protection against interference from cell phones, WiFi antennas, bluetooth devices and even interstellar transmissions, according to Grace.

The m801mk2 also increases low frequency bandwidth for improved phase response, making multi-miked sources sound more musical and open. In addition to sonic enhancements, the m801mk2 also introduces a cosmetic improvement—the external DC power supply has been replaced with a standard IEC cable to create a cleaner, simpler design.


In 1994 Grace Design released the Model 801 microphone preamplifier—their very first production model. For the first time, engineers were reaching for outboard preamps, as the Model 801 provided significantly better performance than the built-in circuits in the recording consoles of the day.

It featured independent circuit boards for each channel, gold contact rotary gain controls wired with precision metal film resistors, gold contact sealed relay signal switching—and perhaps most importantly to the sound, there were NO electrolytic capacitors in the signal path.

12 years later, Grace released the next generation of the Model 801, called the m801.

20 years later, the next generation - the m801mk2 - is here.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
