ART Pro MPAII Microphone Preamplifier

The ART Pro MPA II two channel microphone preamp is the next generation in affordable high performance microphone preamp technology. Each microphone input circuit, with selectable 48v phantom power, features variable input impedance which can radically vary the overall performance of any high quality dynamic or ribbon microphone. The Pro 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 Pro MPA II can operate at either a low or high plate voltage on 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.

Housed in a standard 2 space rack-mountable steel chassis, with CNC routed black anodized aluminum face panel, the ProMPA II is designed to deliver years of reliable operation in the studio, production facility, or on the road for live sound reinforcement.

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
  • Supports Mid/Side Miking Technique
  • Operates at +4dbm/-10dbv Output
  • Selectable Stereo/Dual Operation of Output Controls
  • Automatic Instrument Input Selection

Subject:Awesome Pre
Quality: Very well made piece of equipment. I plan on buying at least 2 more.
Features: It is fine just the way it is. I like the plate voltage adjustment. I also like the ability to use it as a DI box.
Ease of Use: With a little experimenting, not very hard. Plate voltage feature is something you want to experiment with. You can make the same guitar sound very different depending on the voltage you set it at.
Sound: It sounds great. Ten times better than any mixer pre amp. I use it with the ART Pro VLA II compressor. Awesome tone and pristine sound. The clarity is just amazing.
Reliability: Only had it for a few weeks now but use it in a project studio setting. It has been used every day with no apperant defects at this time.
Overall: This baby has a sound that will warm up any mic you decide to use. It sounds really crisp and clean with my MXL V69 Tube mic. It even adds tone and crispness to an SM57. Great pre at a great price.
