Introduction The MP-2NV and the ME-1NV are professional quality microphone preamplifiers designed to recreate the vintage sound characteristics of the early 1970s large consoles. Modern components give the NV Series more clarity, punch and performance under normal use. In addition, features like metering before and after the major gain stages let the user drive them “hard” to greatly expand the range of sonic options.
Gain Staging Front Panel Controls and Buttons The NV Series preamplifiers offer comprehensive gain staging capabilities, controlled by two knobs on the front panel. The large gain knob adds an increment of 5db of gain with each step, while the small output knob, the pot, delivers continuous adjustment of the output level. The input range of the large knob is 0db to 60db and the output range of the small knob is approximately -22db to +10db relative to the "CAL" marking on the front panel.
Be sure to check the polarity of all of your mic inputs when doing a multiple input mix, such as a drum kit, or a guitar amp with several mics. For instance, if you are miking the top and bottom of a snare simultaneously, the bottom mic should have it’s polarity reversed in relation to the rest of the set. If you are miking an open backed guitar amp from in front and in back, the rear mic should have it’s polarity reversed. Listen both ways, at least, to determine what works best for the track.
Mic In Rear Panel Connections The Mic In jack is a female XLR type and uses a standard XLR cable. Its impedance level and phantom power supply are controlled from the channel specific front panel buttons. Pin 2 is hot. Great River Tips: Turn the phantom on and off with the microphone connected, this will assure an equal ramp up and down to both the input transformer of the preamp and the microphone, preventing any inadvertent magnetization.
Specifications Inputs Microphone: 300 / 1200 ohm input (via front panel impedance selector) 3 Pin balanced XLR connector on rear panel (XLR pin 2 is hot) Hi-Z or DI: > 1.
