Brings UA's legendary vintage tube sound into a modern channel strip format.

The Universal Audio LA-610 Tube Recording Channel combines the 610 Mic-Pre/EQ/DI section and a T4 Opto-compressor into a 2RU unit. The 610-tube preamp, DI, and EQ is from UA's TEC-award winning 6176 and is based on the legendary console modules developed by Bill Putnam in the '60s, noted for their musical character and warmth. An ideal front-end for tracking with modern DAWs and for the serious project studio looking for quality UA sound. It uses three 12AX7As, a 6072A, and a 6AQ5 tube for warmth and overall tonal balance. After the preamp section comes the T4 optical compressor, the heart and soul of the famed Teletronix LA-2A.

Who needs An Avalon 737?!

By LA-610 Convert

from Moline, IL

See all my reviews

Probably the hardest part of new gear is being giddy from opening the box to the placement of the unit in your hardware chain. Not so with the LA-610. The part that gets you is after you hook it up, and wait for the tubes to warm (1hour) to perfection - similiar to a fine wine aging on your shelf. I am stepping up from a couple Presonus Eureka's which nearly get me the warmth I desire. Keyboard/guitar/vocals, I will take this wherever I travel - and hope to have this unit for decades to come. You cannot compete with the price. with this performance - and with the recent spike in the Avalon 737 price this unit is a must have. If you must purchase something worth your energy to make a decent sounding album, please I insist, buy the LA-610.


UA LA-610

Very nice piece of equipment. I actually have the MKII version which has LED's for the power lamp and meter lighting. They say they will never burn out or need replacement. It also has true compressor bypass. The pre-amp is warm and sweet. It truely makes the vocals blend with the rest of the mix. You have to be careful with the gain on vocals because it drives the tubes very easily which is a sound I am not fond of. But a wonderful addition if you can afford it.


This is the best period.

Save yourself a lot of disappointment and spend your money on high quality gear. This thing is the best. I make vocals sound like they are a part of the song. It compresses guitar beautifully. It can make nearly any mic sound great. I tried many of the digital tube want to-bees and there is no substitute for UA equipment.


plug in a piece of history

After setting up a 16-track studio about 6 years ago, I wanted to take my tracks to the next level. I have no regrets about this purchase. It makes all my tracks sound professionally done - bass, acoustic guitar, vocals, overhead drums, and electric guitar. If you like the way professionally recorded music has been sounding for the last 40 years, then purchase the one thing that gives it that unique identity (besides a good microphone) and buy an LA-610 - You will be thrilled beyond belief. Now I rarely use any other EQ or compression. This is the most effective piece of equipment I have EVER bought in over 45 years and many thousands of dollars.


That's the sound!

By Anonymous

from Undisclosed

I have used a lot of mid range gear: Focusrite platinum, DBX, TLA audio. I also used Mackie mixers and the like. I acheived good results with that gear but I could never get that "wow" sound. The kind that just sounds perfect when you plug in your mike or bass or whatever. I have since started trying some high end mic pre's. I tried the Focusrite Blue series and it does truly sound amazing. Very pristine though, and I wanted "oomph". That full in your face sound that I have loved for years.I then tried the LA610. I plugged in a fretless Musicman bass. I left the tone flat and the comp at 12 o'clock for both gain and peak reduction.Wow. I mean wow. I have been recording bass for years and... Wow. Full warm and round w/o screwing around endlessly with knobs to try and tame nasty peaks and such. Just a beautiful warm and full sound. I then plugged in a MusicMan fretted bass (Stingray). I have always struggled trying to get that pop and slap to not sound thin. Slap bass always sounded to loud on the high notes and the bass notes would sound dead and too quiet by comparison. The compressor on the 610 worked unbelievably well. Turn the peak reduction up a hair and the bass sounds PERFECT!. It sits in the track w/o ever overpowering everything else.Like dry compressed guitar? Try a strat into the LA610 at high compression and it sounds like "Le Freak"!I then tried a Neumann TLM103 and Audio Technica 4033. The Neumann can be really bright, but LA610 compressor tamed it beautifully. the second you listen back to your track, it just hits you. I have a deep voice, but it can be really nasally and boxy through cheap preamps. It just sounds like David Bowie circa Glass Spider. Wholly crap!My Martin D-28 can be really boomy. I turned the bass down one click, add a little compression and BOOM! Unbelievable!!!!The thing I really noticed was how well everything sat in the mix. Almost no EQ required. No software compressors needed. Everything just sits where it should.I imagine that other high end pre's and comps sound fabulous as well. The Focusrite Blue was amazing, but I wanted more real tube presence. I find that most cheap tube gear just distorts in an egregious manner - not pleasant at all. This thing just nails that beautiful analog sound. The tubes in this provide the fatness I am looking for, and the compressor does not kill the high end like so many cheap ones do. Incredible headroom. Doesn't become flubby in the low end or grating in the midrange/high end.Highly recommended.


This Thing Kills!!!!!!!

By VS-X8gqv

I have tried a LOT of very high end mic pres and compressors lately in my studio. Not just auditioning, but actually using them on projects. This unit has risen to the top of the bunch. It outperforms a lot of other gear costing a lot more. It's one of the best values in pro audio today. Very flexible, and it just sounds awesome. Do yourself a favor and just buy one. I'm getting another one!


LA-610 Universal Audio - Hot!!!

By Andreasthemusic

from Alta Loma, CA

See all my reviews

Somethings just go together - peas and carrots - ham and cheese - peanut butter and jelly - sonny and cher ..... or better yet the LA 610 and any freakin mic out there. Both Neumann TLM103 and AKG c414XL and XLII sounded phenominal. For recording professional vocals - you can't find a more powerful straight forward channel strip with this much headroom and ease of use. SPL control with the utmost clarity and dynamic smoothness like only UA Analog products can produce. Used as a line level and instrument input DI box before the DAW interface to PC is absolutely astonishing - I can't believe I even bothered recording without this in my arsenal before. My USA Fender Stratocaster pumped through the 610 preamp tubes, then more tubes, then LA-2A compression all in one unit then into VST Amplitube 2 via presonus inputs - sounds just as good as my physical 110 watt 4x12 fender stage built tube half stack. 610 preamp and LA-2A optics you ask???? Industry standards that all others aspire to be - this is studio genre fact. Hollywood sounding top studio microphone recording quality and power right in your project studio via this single channel strip. I swear by this thing! Take the brittleness out of your VST Digital recordings, and replace it with world renowned analog warmth before the DAW inputs. Put the sound of a true world renowned console in your signal path and you will no instantly you have been elevated to new heights of audio bliss. Simply put, playing with the big boys now and loving it..... LA-610, rocks!!!!!!
