Versatile Tube Preamplifier Steps Up Your Sound!

ART's Pro MPA-II is a value-packed 2-channel tube microphone preamplifier. It's loaded with the right complement of professional features to deliver a serious sonic upgrade for any project studio or mobile recording studio. For flexible flavor, the ART Pro MPA-II features variable input impedance, so you can dial in a range of tube tones to suit your microphones. What's more, dual-mono and stereo support, and a mid/side miking switch give you the flexibility you need to tackle a wide range of projects and recording setups with the ART Pro MPA-II.

ART Pro MPA-II 2-channel Tube Microphone Preamplifier at a Glance:
  • Two channels of flexible tube preamplification
  • Supports dual-mono and stereo operation, as well as mid/side miking
  • Large VU meters and multicolored LEDs display levels

Two channels of flexible tube preamplification
If you're looking to bring your recordings up to the level, there's nothing like introducing a quality preamplifier. And, with ART's Pro MPA-II, you'll have more than enough sonic range to dial in nearly any sound imaginable - no matter what kind of microphones you have in your mic locker right now, or the microphones you add to it in the future. That's because, on each channel you have selectable phantom power for your condensers. Plus, there's plenty of gain onboard for bringing your ribbon microphone signals up into usable levels. Beyond that, variable input impedance lets you draw out a rich range of tones from each of your microphones - use it to match the preamplifier to your microphones, or creatively mismatch tones for a unique sound. Plus, you can operate the ART Pro MPA-II at high or normal plate voltage, for an even wider range of sounds. There's also a per-channel low-cut filter to squelch issues with rumble.

Supports dual-mono and stereo operation, as well as mid/side miking
Your preamplification needs will vary depending on what you want to do and what you're recording - but, luckily, ART equipped the Pro MPA-II with the flexibility to meet your changing needs. You can operate the preamplifier in dual-mono or stereo, to suit what you're recording. There's even selectable support for mid/side microphone setups.

Large VU meters and multicolored LEDs display levels
Get an eye on what's going on using the ART Pro MPA-II's full assortment of metering. Onboard, two professional VU meters display input or output levels, while its multicolored LED arrays, with average or peak hold, show you tube gain.

Great Tube PreS!

I purchased this used from Guitar Center a few months ago. With it I purchased 2- AX7-C tubes. My Audio Chain: RME800 -> Art MPA2 -> DBX266SX-> KRK reference 6 pair, KRK 10S Subwoofer. This thing heats up the sound so smoothly. Big hearty audio, Tubes, seem to have a unique ability to tune certain frequencies, making it resonate more with less amperage. The lows are so clean. I use this as a PC Gaming Desktop Audio Output. But the tubes themselves are incredible. Very easy to get a clean stereo spectrum with these tubes. High End Tube Hardware for a great price. Final note: This thing is built like a f:;;;; tank. Plan to have a Screw gun ready for taking off the cover if you want to replace the tubes.

Love it!

Running this with some upgraded Telefunken tubes and it's awesome. Got some great vocals and acoustic guitar recordings. Great addition to the studio.

Great Addition to my Collection

If you're getting started into pro audio and are looking to upgrade, this is a great buy. I love this Preamp. Let me put it this way, even if I had a hundred other preamps to choose from I would still deem this worthy of taking up some space in my rack. It might seem like a mediocre preamp at it's price point, but after 2 years of upgrading to better gear I still find myself using it all the time. I can't say that it's my "go to preamp", but, for all it's worth, I am glad it's part of my collection.

Good Stuff!

For the money... you really can't beat this. For lack of a better term... it really smooths out the rough edges. You can really saturate your tone or simply warm it up a bit. I haven't drastically changed my tone with with it, but I know it's capable. Nice piece of gear, and it'll probably sound even nicer with new higher quality tubes. Hard to beat IMHO.

New ToTube Amps

Ran everything through this and wow... I'll never process audio the same again! Beats, bass, pads, and leads all sound so much better warmed up by this amp. If I knew about 'tube amps' ten years ago I wouldn't be so astonished. I'm currently using it to process a Kurzweil K2000 to fatten up it's overall sound and all I can say is 'WIN'! Buy this if you want to GIVE new life to your audio.

Sweetwater Advice

Tyler Berggren

The ART Pro MPA II is the best value in an outboard preamp - bar none. I've got one that lives in my studio and sees A LOT of action. Drums, guitars, vocals, synths - they all enjoy getting a little tube massage. Everything from big, full, and natural to over-the-top hairy tube distortion is on tap here. (Mine shone even MORE when I upgraded the tubes!)
