Regardless of cost, the uniquely musical tonal characteristics of these amplifiers has made them the prized possession of many engineers lucky enough to get the vintage modules, and a "secret weapon" for many studio musicians. Mercury Recording equipment is proud to have a faithful reproduction in the M72s. We have nearly 20 years experience with the amplifiers and feel we have captured the essence not only of how the units behave, but of how they sound overall. We are confident that the addition of modern features makes the M72s much more versatile, without sacrificing the most important feature: Musicality.
Mercury M72s Features
The Gain of the Mercury M72s is variable from 28dB to 58dB, in 3dB increments, controlled with a high quality rotary switch. Also, there is an option of a selectable Input Pad of -16dB or -28dB for even more control. Additionally, when the -28dB pad is engaged and it is set at the lowest gain setting (28dB) you can run signal through the M72s to add warmth and tonality to any tracks, mixes, keyboards, drum machines, samples etc... There are also all the modern features we expect on a new piece of equipment: Phantom Power (on/off) , Phase (Polarity) Reversal, and our amazing sounding F.D.I. (FET Direct Input) circuit per channel.
The Mercury FDI (FET Direct Input) is a proprietary J-Fet circuit, based on a class-A tube topology. The Mercury FDI is designed to reproduce every nuance of a direct recording, while the circuit lets the tube or solid-state character of the amplifier determine the overall tone. The instrument DI signal is sent through the entire microphone pre-amp circuitry, including Mercury?s custom, massive input transformers, so that the individual character of each pre-amp comes through.
The Mercury M72s has the rich lows and punchy mids giving you that instant vocal tone, a realistic acoustic guitar tone, or adding punch to a bass guitar. The same reaction to instruments or source as the vintage module but with slightly more open high end and openness. The Mercury M72s Studio Microphone Amplifier has the vintage tone and break up like the original circuit but it is a bit more musical over all (not cleaner, more musical - there is a huge difference).
