The new Mercury M76m is the latest version of our benchmark Studio Microphone Amplifier. The M76m is based on one of the most sought after vintage amplifier modules, the Telefunken/Siemens V76m. These modules were used in European broadcast and recording studios in the late 1950s and 60s. Later, after tube consoles where out of favor and replaced by discrete, transistor consoles, the V76 modules still lived on and were racked as outboard mic amps and used in the studios around the world.
