This single-rack-space pair of preamps offer the same definitive sonic fidelity and expert craftsmanship as all Great River products. Transparency and vintage harmonic structure are both achieved with NV-Series preamps. The MP-2NV achieves new classic performance status with two discrete Class-A gain stages (the dual gain-stage meters are a Great River exclusive), a front-panel DI input jack which is routed via a FET and BJT buffer through the input transformer (also unique to Great River preamps) for must-hear-to-believe sound from all hi-Z instruments, and a discrete high-current Class-A "big iron" transformer-coupled output amplifier. The MP-2NV is a fundamentally important audio tool that brings out the best in every microphone and instrument. The MP-2NV has an internal power supply suitable for operation on any power grid.A simple change of fuse and proper positioning of a voltage selector will adjust the unit for any voltage between 100 and 240 V AC. The NV Series construction quality is like a beautiful battleship, said one grizzled audio veteran. The item "Great River MP-2NV Mercenary Edition" is in sale since Saturday, October 14, 2017.
