Details
Controls: Input gain (5dB steps to 60dB), output trim (-25 to +10dB, max overall gain 70dB), polarity switch, phantom power switch, input impedance switch (1200/300 ohm), output loading switch (600 ohm), dual-stage input/output metering
I/O: 500-series edge-connector I/O via host rack; front-panel Hi-Z instrument (DI) jack with its own input amplifier. Per manufacturer, identical specs/performance to NV-series rack preamps except for size, weight, and it lacks the rack version's insert patch jack and -10dBV DAW output.
Notes: MSRP per manufacturer site, verified July 2026. FLAG: same NV-series circuit as MP-2NV/ME-1NV, packaged as a 500-series module occupying 2 horizontal slots and powered by the host rack (no internal PSU) — separate row per instructions for form-factor variant. Manufacturer states VPR Alliance-tested.
