The Universal Audio M610 is mono version of the 2-610 , with a simplified EQ section. Other than that, the sound and features are identical to the 2-610. It has the same vibrant high frequency response and deep, gorgeous low end that has graced countless recordings and continues Universal Audio’s reputation for sonic excellence.

Designed by Bill Putnam, the Universal Audio 610 was among the first modular recording consoles. Early Universal Audio consoles were used in all of Putnam's studios including Universal Recording in Chicago and United Western in Los Angeles. Many prominent engineers such as Bruce Swedien began their careers in these studios with this classic rotary knob console. The UA 610 was particularly well noted for its preamplifier, and has left its mark on countless classic recordings from Sinatra to Pet Sounds to Van Halen to LA Woman .

We carefully modeled the UA M610 after the microphone amplifier section of the 610 console. Unlike many vintage "style" mic pres, the M610 is true to the design of its predecessor. Our expertise in analog design translates into a classic tube preamplifier with all of the character of its vintage predecessor, yet designed for the requirements and rigor of the modern studio. We've taken great care to preserve the quality and character of the original, while adding functionality with more boost/cut settings, phantom power, direct inputs and impedance controls.

The Universal Audio M610 Mic Pre is the perfect tool for tracking and ideal when used in conjunction with a Universal Audio compressor such as the 1176LN and Teletronix LA-2A. Whether you're running pure analog or seeking to enhance your digital audio workstation, the M610 will bring classic tube character to your recording.
