Great River ME-1NV Microphone Preamp


SKU: GR/ME-1NV Categories: ,


The Great River ME-1NV Microphone Preamp is a desktop (and rackable) preamp with classic 70s vintage British circuitry.

The Great River ME 1NV has the ability to fine-tune gain effects like in the 1970’s and 1973 era. Transparency and vintage harmonic structure are both achieved with ME-1NV preamp.

The ME-1NV achieves new classic performance status with two discrete Class-A gain stages (a Great River exclusive). Also a front-panel DI input jack which is routed via FET through the input transformer (unique to Great River) for a must-hear-to-believe sound 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.


The main features of the Great River ME-1NV Microphone Preamp include:

  • Multiple In/Out connections: XLR balanced; 1/4″ -10dbV output for ‘no-latency’ DAW monitoring; high-Z input on front panel (disconnects mic input): TRS 1/4″ 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
  • Half-rack-space with internal power supply
