The MP-2NV (two channel mic preamp) greatly modernizes and improves classic British design. This single-rack-space pair of preamps offer the same definitive sonic fidelity and expert craftsmanship as all Great River products, with the ability to fine-tune gain effects like 1970's-era 1073's. 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 FET 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 NV Series’ construction quality is “like a beautiful battleship”, said one grizzled audio veteran.
