The MP-500NV is a professional quality microphone preamplifier designed to
re-create the vintage sound characteristics of the early 1970s large consoles.
Modern components give the MP-500NV more clarity, punch and performance under
normal use. In addition, features like metering before and after the major gain
stages let the user drive it hard to greatly expand the range of sonic options.
All microphones will benefit from the power of the MP-500NV preamplifier,
including dynamic, condenser and especially ribbon types. The MP-500NV uses the
same audio and metering circuit board found in the NV series preamplifiers. This
unit is designed to fit into a 500 series rack using 2 available slots. It
receives its power supply from the host rack. The unit is equipped with a HI-Z
instrument jack that has its own input amplifier and was designed for DI
applications. All specifications and performance details are identical to the NV
series preamplifiers with the exception of size, weight, patch jack, -10dBv
Out.
