The Universal Audio 2-610 is a 2-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 Van Halen.
The UA 2-610 is carefully modeled after the microphone amplifier section of the 610 console. Unlike many vintage-style mic pres, the 2-610 is true to the design of its predecessor. UA'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. The 2-610 preserves 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 2-610 Mic Pre is the perfect tool for tracking and is 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 2-610 will bring classic tube character to your recording.Universal Audio 2-610 Dual-Channel Tube Mic/Inst Pre-EQ Specifications: - Microphone input impedance: selectable, 500 ohms or 2K ohms
