Product Description

The all new ART Digital MPA II is a great two channel microphone preamp with the added versatility of digital output. Like the ProMPA II, each input circuit has 48v phantom power and features variable input impedance which can radically vary the overall performance of any high quality dynamic or ribbon microphone. The Digital 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 input section of the Digital MPA II operates at either a low or high plate voltage applied to 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 and digital output levels. In addition to XLR and 1/4 inch analog outputs, the Digital MPA II features a high quality A to D converter which offers digital connectivity on S/PDIF, ADAT, or AES/EBU outputs. A rotary control on the front panel allows selection of format and sample rates from 44.1 to 192 KHz and 16 bit dithering. There is also a push button for, and two wordclock jacks, allowing loop-through.

The Digital MPA II comes in a standard 2 space rack-mountable steel chassis, with CNC routed black anodized aluminum face panel.

So far very dependable.
Features
What do you consider to be the best features of this product? What features would you add to this product if you could?
It has plenty of IO including AES digital IO. Separate analog and digital output level control. Wordclock pass thru to name a few.
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?
Really easy to use and connect the way you want it. Manual is short but gives you enough info to start using without any problems.
Sound
How is the tone?
Great. Numerous ways to get the sound you want. Plate voltage, input impedance or input gain. Easy to change tubes too for a different character.
Reliability
How has it stood up over time?
Didn't have it for very long but no problems so far. Feels solid.
General
Your general opinion of this product.
You can buy other models but this seems most flexible and AD/DA (192k capable) with numerous including pro interface options is great to have.
