Product 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.

  • Variable Input Impedance For Flexible Microphone Voicing (150 Ohms To 2400 Ohms)

Very happy with my purchase
General
Your general opinion of this product.
I bought this unit to get my mics on a better pre, instead of interface pre. I use it with a Zoom R16. don't listen to the bloggers on gear sluts, this unit definitely improved my front end, don't get me wrong i still need a better interface eventually.
Quality
Would you consider this product to be made well? How dependable?
Unit is a tank. Like all electronics it is an issue of the internal guts lasting. Time will tell.
Ease of Use
How easy is this product to use? How easy is the product to use with other products? Did it take long for you to learn to use this product? Was the manual helpful? How playable do you consider this product to be?
Super easy to use. just get the VU meters set for your particular interface and it's almost as easy as turning up a gain knob. I say that a little cautiously because unlike just turning up a gain knob this puppy has options, like the Impedance match, low cut filter, plate voltage, etc... i find myself spending about 10 minutes pre-record dialing the unit in to craft the cleanest signal possible. hopefully it gets faster with experience.
Features
What do you consider to be the best features of this product? What features would you add to this product if you could?
There are too many good features to list just one, but I do like the M/S function, but since you have two pre's you can do Blumlein pair also. I wish you had an option like on the Art Compressor VLA II to look at the meters in either input or output stage.
Sound
How is the tone?
This unit is amazing if you take the time to tweak your tone. Also do yourself a favor and pair it with the Art Pro VLA II. This combination is a knock out. My recording already sound more transparent, a huge plus when it's time to go back in the box and add Reverb's and other effects. i notice i can add more, although less is more, without my S/N ratio sounding like crap.
Reliability
How has it stood up over time?
Just got it, but outside of the external build quality, which i said is a tank, it's all about the guts. For you newer project studio guys check out the Sound on Sound review for both the MPA and the VLA. if you can read through he typical British underhandedness you will see that these units are one definite bang for the buck. granted they aren't Neve or Meridian or Great River. but as a first go to pre you could not ask for more and it works on a budget.
