In addition to a spiffy new, silver-face look, which matches the rest of the UA 610 line, the 2-610S stereo mic pre has been improved with all of the best features UA has brought to the 610 design series. The 2-610S has the same great signature sound that Universal Audio customers have grown to love with the 2-610.

Popular new features like a -15dB input pad maximize the usefulness of your 2-610S with your entire microphone collection. The 2-610S also includes circuit upgrades which improve frequency response and gives the 2-610S the same open sound as its channel strip cousins, the 6176 and LA-610.

The Universal Audio 2-610S is a two-channel tube microphone preamplifier based on the legendary Universal Audio 610 modular console. 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.

Universal Audio carefully modeled the UA 2-610S after the microphone amplifier section of the 610 console. Unlike many vintage "style" mic pres, the 2-610S is true to the design of its predecessor. Universal Audio's 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. They'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 2-610S 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 2-610S will bring classic tube character to your recording.
