The ART 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 ART 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 analogue VU output meters display output levels while multi-coloured LED arrays, with average or peak hold, show tube gain and digital output levels.
In addition to XLR and 1/4″ analogue outputs, the ART 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-word clock jacks, allowing loop-through.
The ART Digital MPA-II comes in a standard 2u space rack-mountable steel chassis, with CNC routed black anodised aluminium face panel.
