ART Digital MPA-II Microphone Preamplifier
The ART Digital MPA-II 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.
Features:
– Variable input impedance for flexible microphone voicing (150 Ohms to 2400 Ohms)
– Selectable plate voltage
– Large VU meters
– Backlit function switches
– Discrete Class-A input microphone preamplifier
– Low noise at lower gain settings
– Extremely low total harmonic distortion (THD)
– Wide frequency response
– Additional front mounted instrument input jack
– Operates at +4dbm/-10dbv output
– Selectable stereo/dual operation of output controls
– Automatic instrument input selection
– 24-204KHz external sample rate
– 44.1K, 48K, 88.2K, 96K, 176.4K, 192K internal sample rates
– 24/16 bit switchable dithering
– Wide dynamic range A/D
– Rotary Encoder for quick selection of sample rate
– Separate analog and digital output level controls
– Digital Level LED meters display both Average and Peak level
– ADAT optical I/O
– Sync to incoming ADAT data rate
– Switch selectable optical output (S/PDIF or ADAT)
– AES/EBU and S/PDIF outputs
– Two wordclock jacks allowing loop throughThe 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 2u space rack-mountable steel chassis, with CNC routed black anodized aluminum face panel.
