The new Mercury M72s [Mk. IV] is our flagship, valve Studio Microphone Amplifier. The M72s is based on the most sought after vintage amplifier module—the Telefunken/Siemens V72s—which is most famous for being installed in REDD.37 consoles, used on all the early Beatles recordings by George Martin at Abbey Road Studios in London, England.

You may notice the new Mercury M72s was stripped of a few vintage inspired, aesthetic extras of the MK II [which is still available as the M72s-CSV, custom shop version] but is still loaded with the same exact tone and warmth utilizing the same exact circuit, same quality parts and same transformers we have used since we started building the first M72s at Mercury Recording Equipment.

The Mercury M72s is based on the module used in consoles which are very rare due to a minimal amount made. The more common V72 amplifier modules (not marked with the lower case s, i.e. V72s) were later modified and have been sold for many years as outboard preamplifiers all over the world. Neither of these amplifier modules have been available new for more than 50 years. So, working units have become extremely rare, very expensive and in some cases are now in need of much repair. 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 20+ years of experience with the amplifiers and feel we have captured not only how the units behave, but how they sound overall. We are confident with the addition of modern features, making 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 FDI (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 preamp circuitry, including Mercury’s custom, massive input transformers, so that the individual character of each preamp comes through.

The Mercury M72s has the rich lows and punchy mids giving you that 'instant' vocal tone, or assisting with a realistic acoustic guitar tone, punch to 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 that "vintage" tone and break up like the original circuit but it is a bit more musical over all (not cleaner, but more musical—there is a huge difference).
