What We Think

Great River has taken a familiar design and in a lot of ways improved upon it. When it comes to sound, the often unwieldy low-mids that a classic 1073 (or 1073 clone) will tend to have are much tighter and punchier with the Great River preamp. Also, the hi-freq response reveals much more detail than its inspiration. Key features like the “loading” button that engages a 600 ohm resistor before the output stage open the door to a ton of sonic variations. Also, switchable input and output metering really set this preamp apart in the ever-growing sea of Neve-inspired hardware.

When I use it on rock vocals, it adds a weight and texture that is simply to die for. This is also my go-to pre for overhead recordings, where the high frequencies are delivered in a warm, controlled manner and the drums sound punchy and thunderous. Being a Neve-inspired unit, it shares the same source flexibility, so while I have my favorites, it performs exceptionally all throughout the studio. I also really like the DI of the Great River. They managed to implement a FET-buffered route for the instrument signal to pass through the custom wound Sowter transformer. This makes the DI much more than an afterthought which, let's face it, on some mic pres that's exactly what it is. I often go with its DI over my pricey dedicated DI units.

Manufacturer's Description from Great River

The ME-1NV (single channel mic preamp) greatly modernizes and improves classic British design. This desktop (and rackable) preamp offers 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 ME-1NV 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 ME-1NV is a fundamentally important audio tool that brings out the best in every microphone and instrument.

ME-1NV FEATURES:

Multiple In/Out connections: XLR balanced; ¼" -10dbV output for 'no-latency' DAW monitoring; high-Z input on front panel (disconnects mic input): TRS ¼" insert patch point for compressor or equalizer ahead of the output amplifier

Adjustable gain stages: input in 5db steps to 60db; output from -25 to +10db; maximum overall gain 70db; 2 to 3 stages of single ended solid state amplifier gain blocks, depending on gain structure; high-current 70ma Class A bias on output stage

Input and output meters on each channel (dual-stage metering is a Great River exclusive)

Front panel switches: polarity; phantom power; input impedance (1200 / 300 ohm); output loading (600 ohm resistor across output transformer)

High quality, custom wound Sowter transformers

Gold plated switching contacts

Internal power supply

110 or 220 volt operation with external selection, either 50 or 60 Hz

3 year warranty with registration

Half-rack-space with internal power supply

'Big Iron Vintage Sound' from custom-wound transformers

'No-latency' output monitoring for DAW users

High-Z input is ideal for bass, guitar, and sound modules (FET-buffered and routed into the input transformer, a Great River exclusive)

Gain stage monitoring via dual meters (also a Great River exclusive)

Ultra quiet noise floor for outstanding performance at any gain setting

The EQ-1NV (one channel equalizer) greatly modernizes the classic British “1081/1083”-type design. This “desktop” (and rackable) digitally controlled analog parametric EQ offers similar topology to vintage 1081/1083 models, but with welcome improvements. Newly designed Class-A discrete single-ended amplifiers and true inductor/capacitor (L/C) circuitry add greater clarity and dynamic range to the musicality of the vintage-era models. The EQ-1NV also has a unique discrete high-current Class-A balanced output stage.

To make life in the studio (and on the road) easier, the EQ-1NV has been specifically designed to integrate with the patch loop in Great River NV Series microphone preamplifiers (with a single TRS ¼” cable), for complete flexibility in tracking and mixing. The front panel input selector / sensitivity switch offers the option of using the signal from the EQ-1NV's transformer-coupled line input (ranging from +8dbm to -20dbm), or the patched signal from the NV preamp. When connected via the patch loop, the four EQ sections are inserted between the microphone (or DI) input’s first gain stage (with level control and metering) and the preamplifier’s output gain stage and "big iron" transformer (also with level control and metering). This routing flexibility provides a broad range of sonic/harmonic possibilities and maintains a full Class-A signal path.

“It’s the best EQ I’ve ever used”, said a prominent pro audio magazine editor.

EQ-1NV FEATURES:

One channel, discrete Class-A design
Multiple In/Out connections: XLR balanced line in and out; ¼" -10dbV output for 'no-latency' DAW monitoring; TRS ¼” insert patch point for NV Series mic preamp (inserts EQ between NV preamp gain stages)
Wide range of input sensitivity from +8dbm to -20dbm with selection between line in and insert patch point
4 bands independently enabled with +/-15db boost/cut
Hi and low bands selectable between peaking and shelving
Hi-mid and low-mid bands each have 3 selectable Q positions
3rd order selectable frequency high pass filter
Hardwire bypass of equalizer section
Internal low-noise shielded power supply (externally selectable for 110 / 220 volt; 50 / 60 Hz)
3 year warranty with registration

About Manufacturer

Great River Electronics Inc. designs, manufactures, and markets superior quality professional audio products that are built to perform and capture your sound with integrity, character, and accuracy. The company has an experience base in excess of twenty years in analog and digital domains of audio processing. In addition, the company also designs industrial control systems used in commercial applications. Great River Electronics Inc. is located just southeast of the capital city St. Paul, Minnesota. Dan Kennedy, co-founder of Great River Electronics Inc., began designing microphone preamplifiers to solve noise problems associated with recording orchestral music using ribbon microphones. Intelligence, perseverance, and passion yielded product designs that are supremely quiet, clearly transparent, and extremely musical across all musical genres and tracking formats. The combination of crystal clear high-end coupled with tight, solid low-end result in precise, full sounds that realize their natural sonic positions within any mix. In addition, Dan has designed an equalizer, EQ-2NV and EQ-1NV, to complement the NV Series preamplifiers or to function as a standalone equalizer. The design philosophy at Great River Electronics Inc. has always been to utilize the minimum circuitry necessary to provide maximum sonic performance. Legendary Jensen and Sowter transformers optimized for Great River Electronics Inc. are used in all microphone preamplifiers. In addition, all units are equipped with gold plated switch contacts, operate on externally switched 110 or 220 volts, and have a standard two-year warranty with registration. These preamplifiers are widely used internationally in professional recording studios, digital project studios, and road recording rigs. The units are designed as perfect front-end additions to digital audio workstations (DAWs). Two design types of preamplifiers are currently available - Original MP Series, the clean series, and the newly developed NV Series, the vintage sound series. The Original MP Series, the MP-2 and the MP-4, are two channel and four channel units that offer the most pristine, definitive sound clarity and accuracy available today. These units have optional output transformers to isolate and balance the signal. The NV Series, featuring the MP-2NV and the ME-1NV, modernize vintage sound. Both units are tunable preamplifiers that offer the same definitive sound and solid craftsmanship as all Great River Electronics preamplifiers with the ability to 'tune that sound' a la 1970's 1073's. The equalizers, EQ-2NV (two channel) and EQ-1NV (one channel), are loosely based on the topology of vintage 1081/1083 models. The newly-designed class A, discrete single-ended amplifiers in the EQ-NV Series bring greater clarity and dynamic range to the musicality and control of the 108x models. The EQ-2NV and EQ-1NV use the same internal components and have identical and stunning sonic performance capabilities. Great River Electronics Inc. understands the needs, demands, and mission of today's busy recording professionals - produce great music with great sounds and great performances accurately articulated and meticulously defined every time.
