The Digital MPA-II 2-Channel Microphone Preamp from ART delivers all of the same great features of the ProMPA 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 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″ 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 2u space rack-mountable steel chassis, with CNC routed black anodized aluminum face panel.
