Universal Audio LA610-U MkII Classic Tube Recording Channel Strip

The Universal Audio LA-610 MkII is a modern reimagining of a classic all-tube recording channel strip, combining the iconic 610 mic preamp with a smooth T4 optical compressor. Designed for professional and project studios, it delivers warm, musical analog character inspired by legendary recordings.

Built on the historic Bill Putnam 610 circuit, the preamp section provides rich tone shaping with EQ and variable impedance control. The integrated compressor is based on the famous LA-2A-style T4 optical design, known for its smooth, program-dependent response and natural leveling.

With improved metering, true bypass operation, and enhanced output performance, the MkII version offers modern reliability while maintaining vintage sonic character. It is a powerful front-end solution for recording vocals, instruments, and studio sources with classic analog warmth.
