Get to know them!

The LA-610 MkII brings Universal Audio's legendary vintage all-tube sound into a modern channel strip format by combining their 610 mic pre/EQ/DI and T4 opto compressor into a single 2U chassis with a pricetag any serious project studio can afford. The Mark II version of UA's famous LA-610 sports true bypass on the compressor circuit, larger metering, increased output signal, and super-cool black-on-black cosmetics. If you're looking for incredible sound that's steeped in history, check out the LA-610 MkII.

A modern studio classic

The LA-610 MkII is a re-tooled version of UA's best-selling professional audio channel strip. Audiophiles here at Sweetwater particularly appreciate the MkII's compressor circuit true bypass and the optimized output signal. The MkII has also been given a unique exterior cosmetic upgrade, and its distinctive look sets it clearly apart from the classic LA-610. The unit packs tremendous sonic versatility and is an ideal front end for tracking with modern DAWs and the serious project studio seeking authentic UA sound. Handcrafted in Universal Audio's Scotts Valley, California labs, the '610 offers weapons-grade build quality and colorful sonic character at an accessible price.

An ideal front end for your studio

The tube preamp/DI/EQ section of the LA-610 MkII is based on the legendary console modules developed by Bill Putnam in the late 1950s and early '60s. From The Beach Boys to Van Halen to Coldplay, countless classics have been recorded using these preamps, noted for their musical character and warmth. After the preamp section, the '610 offers a T4 optical compressor with true bypass. The electro-optical detector (T4 cell) is the very heart and soul of the Teletronix LA-2A. The unique combination of electroluminescent panel and photo-resistors inside the T4 are the crucial circuit components that give both these compressors their signature sound. The simple operation and program-dependent nature of the T4 compressor provide the same extremely musical control that has made the LA-2A such a well-loved classic for over 50 years. As a channel strip, the LA-610 MkII packs tremendous sonic versatility and value. It's an ideal front end for commercial, project, and home studios alike.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
