You'll experience the pinnacle of audio performance with the ART Digital MPA-II Professional 2-Channel Microphone Preamplifier with Digital Out. This state-of-the-art device retains all the exceptional features of the ProMPA, enhanced with the added convenience of digital output.

Each input circuit is equipped with 48v phantom power and boasts variable input impedance. This unique feature allows you to drastically alter the performance of any high-quality dynamic or ribbon microphone, providing you with unparalleled control over your audio output.

The Digital MPA-II is a versatile tool, capable of being configured for dual mono or stereo operation. It also supports selectable mid/side mic, summing the adjacent channel to decode left/right signals, offering you a wide range of audio possibilities.

The input section operates at either a low or high plate voltage, applied to the two integrated hand-selected 12AX7 tubes. This feature allows for a broader variation of preamp tone and performance, ensuring you get the best sound quality possible.

The device features large back-lit analog VU output meters that display output levels, and multi-colored LED arrays that show tube gain and digital output levels. These can be set to average or peak hold, giving you a clear visual representation of your audio levels.

The Digital MPA-II is not just about analog outputs. It also features a high-quality A to D converter, offering digital connectivity on S/PDIF, ADAT, or AES/EBU outputs. A rotary control on the front panel allows for easy selection of format and sample rates from 44.1 to 192 KHz, and 16-bit dithering.

The device also includes a push button for, and two wordclock jacks, allowing loop-through. All these features are housed in a standard 2u space rack-mountable steel chassis, with a CNC routed black anodized aluminum face panel, ensuring durability and a sleek, professional look.
