ART ProMPA II - 2-Channel Tube Mic Preamp
The new ART ProMPA II 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 ProMPA 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 ProMPA 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 rack unit 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.Variable Input Impedance For Flexible Microphone Voicing (150 Ohms To 2400 Ohms)Selectable Plate VoltageLarge VU MetersBacklit Function SwitchesDiscrete Class-A Input Microphone PreamplifierLow Noise at Lower Gain SettingsExtremely Low Total Harmonic Distortion (THD)Wide Frequency ResponseAdditional Front Mounted Instrument Input JackSupports Mid/Side Miking TechniqueOperates at +4dbm/-10dbv OutputSelectable Stereo/Dual Operation of Output ControlsAutomatic Instrument Input Selection
