Quick Overview

Great River MP-500NV+PWM-501 Mic Preamp/Compressor Bundle brings you professional quality and versatility!


The Great River MP-500NV preamp module for the '500' series rack is now available! 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.


The PWM-501 is an ultra fast, ultra versatile compressor in 500-series format from the legendary Great River.  It's fast like a FET or VCA but it has the coloration that is different and of its own form because it uses a Pulse Width Modulator as a gain control element.  It's versatile because it offers both Feed Back and Feed Forward compression, and has a built-in second order high pass filter on the side-chain.
