Mercury M72s Dual-Channel Tube Microphone Preamp

The Mercury M72s is our flagship, all tube studio microphone amplifier (preamp). The Mercury M72s is based on the most sought after vintage amplifier module in the world—the Telefunken/Siemens V72s—made 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.

We based the Mercury M72s on the specially produced module used in recording consoles from that era. Because the original recording console modules were manufactured in such small quantities, they have become extremely rare. 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 the original V72 or V72s amplifier modules have been available new for more than 50 years, and working units have become extremely rare, very expensive and in some cases are now in need of extensive repair. Regardless of cost, the uniquely musical tonal characteristics of these amplifiers has made them a prized possession for engineers lucky enough to use the vintage modules, and has become a "secret weapon" for many studio musicians.

Mercury Recording Equipment is proud to introduce a faithful reproduction of the original, the Mercury M72s. Because we have over 20 years of experience repairing, modifying and racking the original amplifiers, we have been able to very accurately capture the behavior, and the legendary sound of the original. We have also included all of the modern features not available on the original units including, +48V phantom power, phase reverse and pad, as well as a direct input for guitars, bass, and keyboards.

Every microphone you plug into the M72s will sound better. If you are looking for your next “secret weapon”, the Mercury M72s is for you.
