The MP-QR is a rack mountable unit that contains four independent microphone preamplifiers. All inputs and outputs are active balanced and terminated in XLR connectors.
The wide, trim pot adjustable gain range and the individually switch selectable phantom power supplies make the unit easy to use with almost any microphone.
With its low noise, high quality circuitry combined with rugged construction, the MP-QR microphone preamplifier is a unit that will give years of trouble free service.
