The Great River MP-500NV is a VPR-Alliance compliant, 2-space, 500-series preamp that uses the same audio and metering circuitry found in the NV-series preamplifiers
The MP-500NV is a professional-quality microphone preamplifier for the 500 series that recreates the vintage sound characteristics of the early 1970s large-format consoles. Rather than create a clone, the MP-500NV uses modern design techniques and components to give the MP-500NV more clarity, punch and transparency under normal use. However, if you’re looking to add a little vintage color, features such as metering before and after the major gain stages let you drive it creatively to greatly expand the range of sonic options. Any microphone will benefit from the power of the MP-500NV preamplifier, including dynamics, condensers, and ribbons. While the MP-500NV uses the same audio and metering circuitry found in the NV-series preamplifiers, it’s designed to fit into a 500-series rack using 2 available slots. Powered from the host rack, the MP-500NV is equipped with a Hi-Z instrument jack that has its own input amplifier, designed specifically for DI applications, rather than being an afterthought. All specifications and performance details are identical to the NV series preamplifiers with the exception of size, weight, patch jack, -10dBv Out. The MP-500NV is VPR-Alliance compliant and tested.
