Great River MP-2NV

The Great River MP-2NV is a dual-channel microphone preamplifier inspired by revered 1970s British console designs, refined and elevated for modern professional recording environments. Housed in a single rack space, it delivers the uncompromising build quality, reliability and sonic authority for which Great River is known.

The NV Series captures the unmistakable harmonic richness and weight of vintage British circuits, while maintaining the clarity and headroom demanded by contemporary production workflows. The result is a true “new classic” — equally at home in commercial studios, broadcast facilities, and high-end project rooms.

Discrete Class-A Signal Path

At the heart of the MP-2NV are two fully discrete Class-A gain stages per channel. Great River’s exclusive dual gain-stage metering provides precise control over input and output drive, allowing engineers to move seamlessly between pristine transparency and harmonically enhanced saturation.

A front-panel high-impedance DI input is routed via a FET and BJT buffer through the input transformer, a distinctive Great River topology that delivers exceptional depth and dimensionality from guitars, basses and synths. The high-current Class-A, transformer-coupled output stage ensures authoritative low-end response and unmistakable analogue weight.

Engineered for Professional Environments

Designed for global deployment, the MP-2NV features an internal power supply compatible with 100–240V AC operation. Voltage selection is straightforward via fuse change and selector adjustment, making it suitable for studios and touring applications worldwide.

Construction is uncompromising often described as “built like a battleship” reflecting the robust mechanical design and meticulous component selection throughout.

A Modern Essential with Vintage Soul

Whether tracking vocals, drums, orchestral sessions or DI instruments, the Great River MP-2NV consistently enhances source material with depth, dimension and authority. It is not merely a microphone preamplifier, but a foundational recording tool for engineers who demand authentic analogue character without sacrificing precision.
