Upgrade Your Sound with Two Channels of Tube Warmth!

Boost your sound with the ART Pro MPA II microphone preamplifier. This high-performance, tube-based mic pre offers two channels for either dual mono or stereo miking, +48V phantom power, a handy mid/side miking switch, large VU meters so you always know where your levels stand, and much more. Conveniently, the Pro MPA II boasts variable input impedance, so you can custom tailor your tone to get the most out of any dynamic or ribbon microphone. With this mic preamp, you gain more than just gain -- you get the flexibility to apply tube warmth to your recordings, no matter what kind of microphone you're using, as well as the presence, clarity, and high-end hardware for which ART is known.

2 Channels of Tube Tone

On each of the two microphone input circuits, you have selectable +48V phantom power plus variable input impedance, which can help you extract a wider range of tones out of a microphone -- try tweaking it on a ribbon mic! You can use any high-quality condenser, dynamic or ribbon microphone with the Pro MPA II.

For even wider variation of preamp tone and performance, operate the Pro MPA II at either a low or high plate voltage on the two integrated 12AX7 tubes.

Meant for Dual-Mono, Stereo, MS Recording -- You Name It

Since the Pro MPA II microphone preamp can be configured for either dual mono or stereo miking, you have the flexibility to match the unit to your recordings and get optimal sound every time. Want to record acoustic guitar or drum overheads? No problem! The Pro MPA II is up to the task.

Selectable mid/side mic support makes it easy to capture pianos, acoustic guitar, drum overheads, strings, and more. Just hit the Mid/Side Matrix switch when you're miking in a middle/side configuration.

Big VU Meters

Large back-lit analog VU output meters let you check input or output levels at a glance, and multi-colored LED arrays, with average or peak hold, provide a clear visual display of tube gain (warmth).

Built to Last

The professional Pro MPA II looks sharp in any studio, production facility, or live sound setup. Housed in a standard 2U rackmountable steel chassis, the durable mic pre features easy-to-read white screen-printed text against a CNC-routed black anodized aluminum face panel.

- 2-channel tube-based microphone preamplifier

Customer Reviews
4.5 out of 5 (19 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Best in class --but swap out the tubes"
Sound: This product is the best in its class. I have tried pretty much all the cheaper tube-based preamps and this product is by far the best. That said, the stock Chinese tubes are not very good and I would highly recommend upgrading them, preferably with vintage "New Old Stock" tubes. (12AT7 tubes work well, as well as many others in the general family that includes 12AX7's that are the stock item. Don't be afraid to experiment! I found a number of nice choices.) Quality: I have a slightly older Art MPA II digital unit and I was pleasantly surprised to discover that the new MPA II has better front-end gain. Same model names, but I guess Art has been quietly improving them. Value: Best in class. When comparing prices with cheaper low-voltage units, remember that many of them are mono, and that this unit has two channels. It is worth the few extra dollars --for sure. As I said above, replace the tubes --easy to do and makes a big difference, given a good vintage tube. The Wow Factor: Basic design. Not "sexy" but functional. What more do you need? Overall: If lost, I would replace it. Many other tube preamps I would not replace...

zZounds has verified that this customer bought this product from us. "Great Preamp for Stereo recording"
Sound: I use this mostly for stereo micing on acoustic guitar and drum overheads. I use a Universal Audio 710 for vocal recordings. I have usaed the ART for vocals but it doesn't quite do the job I want it to. But on acoustic guitar with 2 mics, it's amazing! There are lots of options for shaping a great sound. In stereo mode, the right channel output knob becomes a pan pot which I think is pretty cool. The mod-side matrix is also a great feature. I changed my tubes in this for a pair of EH 12AX7's and that really really helped too. I recommend anyone buying this to do the same. Feature: Lots of features for a preamp this cheap. I had to play around with them for a little while to really grasp it. But a lot can be achieved with this product. Quality: Great quality. Solid build. Value: For under $300 this thing is a steal! The Wow Factor: This has a really sleek look on my rack. Looks very pro. Overall: This unit gets a ton of use in my studio. I have used and own high-end equipment and I still use this preamp a lot. If it breaks, I will buy another one. But I must say that this has given me not one single problem at all. Really great product and value.
