## Description

The ART Pro MPA II two channel microphone preamp is the next generation in affordable high performance microphone preamp technology. Each microphone input circuit, with selectable 48v phantom power, features variable input impedance which can radically vary the overall performance of any high quality dynamic or ribbon microphone. The Pro MPA II can be configured for dual mono or stereo operation with selectable mid/side mic support, summing the adjacent channel, to decode left/right signals. The Pro MPA II can operate at either a low or high plate voltage on the two integrated hand-selected 12AX7 tubes for wider variation of preamp tone and performance. Large back-lit analog VU output meters display input or output levels while multi-colored LED arrays, with average or peak hold, show tube gain. Housed in a standard 2 space rack-mountable steel chassis, with CNC routed black anodized aluminum face panel, the ProMPA II is designed to deliver years of reliable operation in the studio, production facility, or on the road for live sound reinforcement.

## Questions & Answers

**Q: Anybody tried the MPAII with high quality condensers? I want to try it with a pair of Audix scx25a's, wondering if it will warm up the sound.**
A: I've used it with both AKG 414s and a TLM103 and was pleased with the unit's ability.  I did mess with the controls a bit to "tune in" the nicest sound.  This particular preamp got a very high rating in Sound On Sound Magazines Mic Pre "shoot out."  They put it up against Pres costing several times more and it actually won praises in several categories.  Warning:  I bought (2), returned one as non working. Now the second unit is having meter issues. (meter light tuns on and off randomly.

**Q: will this work in europe? the picture says 250 volt, but there are some confusing answers by the community...**
A: There is no switch but by the power plug input there is a fuse (250V / 0.5A). My best guess is there are EU versions with different fuses for different power loads but I would call ART to be sure. It may work out of the box!

**Q: Will changing the tubes void the warranty?**
A: I don't know. It may.

**Q: What are the steps on how I can connect this to my Scarlett Focusrite 2i2 audio interface? I'm al planning to upgrade to the 6i6, any differences?**
A: I'd recommend skipping the 6i6 and going up to the 18i8 or 18i20 the 6i6 doesn't have enough inputs. In terms of audio quality you won't notice an improvement between Scarlett they all sound good

## Customer Reviews

### ⭐⭐⭐⭐⭐ Beautiful unit, hands down.
*by B***N on June 10, 2015*

If you are looking for your first pre-amp (or a versatile swiss army knife of a unit for your rack) and there is any doubt in your mind over buying this pre take it from me personally that this is worth it. The only bad thing I could manage to find is the tubes are sub-par to the rest of the unit, which those are easily upgraded. Everything is wonderful, the metering is accurate and the controls are simple and sturdy. It adds plenty of flavor to your mics; I use an Shure Sm7b which is relatively flat and this pre warms it up beautifully. It has all the gain you'll ever need and the impedance control can totally flip the sound of your mic from open and large to tight and in your face. The adjustable voltage function squeezes an entire new flavor into the unit, which makes it incredibly versatile on a very large array of sounds. One of my favorite uses is the High Z Instrument input on the front. I love the way this unit warms up a bass guitar before sending it into a DI. On terms of quality, this box holds nothing back. If you are mixing music primarily "in the box" and don't have any hardware, I highly recommend this unit to start.

### ⭐⭐⭐⭐⭐ Sounds like butter!
*by J***N on April 5, 2024*

OMG, this preamp makes my guitars, especially my acoustic, sound like butter. The tube warmth is definitely worth the price. I have my vocal microphone on one channel and my guitar on the other, both feeding an AXE IO usb interface. I can drive the guitar channel into the warmest distortion you’ve ever hear. Butter, butter, butter!! This makes me want to get the smaller single channel tube preamp from Art to take for open mic night!

### ⭐⭐⭐⭐⭐ Perfect!
*by M***E on June 9, 2014*

I am an audio engineer since 2010 acquiring my audio engineering certificate from MAXIM Entertainment Group.These are extremely reliable and durable. Very easy to swap out the stock tubes if you feel you'd like to play with different tubes. I cannot express enough how clean and perfect this preamp is for all recording needs. I have never had a problem with these, I have 3 of them. I also have an Avalon 737, and comparing the two, these ART's with Tungsol Gold Pin tubes are a beautiful matching. If you're starting your own studio or looking for a quality preamp that won't break the bank, these bad boys with get any job done.These have sounded great with any mic I have used with them.
