LA-610 MkII Classic Tube Recording Channel

The LA-610 MkII combines an all-tube, vintage mic preamp design with authentic Teletronix T4 opto-compression circuitry. This classic channel strip design, with its warm preamp tone and smooth, natural-sounding compression, features true compressor bypass, a large easy-to-read meter, high output level, and an auto-switching power supply.

Manufacturer's Description from UA

All-Tube Dual Channel Preamplifier — Based on the Legendary UA 610 Modular Console. 

The legendary, Bill Putnam Sr. designed, UA 610 modular console is particularly well noted for its preamplifier, and has left its imprint on countless classic recordings from Frank Sinatra and Van Halen, to The Beach Boys’ Pet Sounds. The 2-610 builds on this foundation by adding enhanced, user-requested features and build quality with a new cosmetic treatment. The result is a classic dual-channel tube preamplifier with all of the character of its vintage predecessor that meets and exceeds the requirements of the modern studio. Whether running pure analog or enhancing a digital audio workstation, the 2-610 brings classic tube character to any recording project.

At our users' requests, the 2-610 has the extended top end shared by its cousins, plus a -15 dB pad. In addition, the 2-610 has improved stability in the feedback design of the shelf filters as well as an improved power supply. Our expertise in analog design translates into a classic tube preamplifier with all of the character of its vintage predecessor

Features:

  • All-tube dual channel preamplifier derived from legendary Bill Putnam-designed 610 modular console
  • Variable impedance Input, Gain, and Output levels
  • High and Low shelving EQ
  • Mic, balanced line and Hi-Z inputs
  • Custom wound double sized alloy transformers
  • Front panel -15 dB Pad switch
  • Improved EQ circuit and more “open” sonics
  • Ultra quiet operation
  • Updated “silverface” cosmetics; enhanced build quality
  • Hand-built in USA; backed by 1-year limited warranty

About Manufacturer

Universal Audio Inc. was re-founded in 1999 by Bill's sons, James Putnam and Bill Putnam Jr., with two main goals: to faithfully reproduce classic analog recording equipment in the tradition of their father, and to design new digital recording tools with the sound and spirit of vintage analog technology. However, as Bill Jr. recounts, the genesis of "UA, part 2" is actually a bit more serendipitous.

Having grown up in the music industry, Bill Jr. and James ("Jim") Putnam naturally assumed that the music business is where they'd eventually end up. Jim, a touring musician and recording engineer, and their older brother Scott, a studio designer in Southern California, were the first to follow in Bill Sr.'s path. However, Bill Jr. took a more circuitous direction, working for a number of engineering companies before undertaking a doctorate in Electrical Engineering at Stanford University. It was at Stanford that Bill Jr. became closely involved in the Center for Computer Research in Music and Acoustics (CCRMA), specializing in signal processing. It was also at Stanford that Bill Jr. began to assemble a team of the best and brightest minds in the field — who continue to steer many of Universal Audio's engineering efforts to this day.

However, the precise event that led Bill and Jim to start (or "reinvent") Universal Audio in 1999 was unexpected. As Bill Jr. tells it, when Bill Sr. passed away in 1989, he and Jim were faced with the Herculean task of cleaning out their dad's workshop and storage areas. While going through Bill Sr.'s old test equipment, boxes of parts, bits and pieces of consoles, and half-cannibalized 1176 compressors, Jim came across their father’s old design notebook. The two spent the evening poring over his notes, realizing that this was the map to every technical problem their father had ever solved. It was at that moment that they decided to bring back Universal Audio and its classic products. 

Fast forward a decade. Now with nearly 80 employees and legions of new customers worldwide, UA is headquartered near the Silicon Valley, in Scotts Valley, California — where our classic analog gear is still hand-built, one unit at a time. The lengths we go to deliver the exact sound and performance of classic analog audio gear is unparalleled; in fact, the goal is for UA's modern units to perform identically to well-maintained units built decades ago. 

Of course, analog is only half the story. At Universal Audio, we employ the world's brightest DSP engineers and digital modeling authorities to develop our award-winning UAD Powered Plug-Ins platform, featuring the most authentic analog emulation plug-ins in the industry. Our DSP gurus work with the original hardware manufacturers — using their exact schematics, golden units, and experienced ears — to give UAD plug-ins warmth and harmonics in all the right places, just like analog.
