A classic tube microphone preamp and 1176LN compressor in a single unit.

The 6176 Vintage Channel Strip combines the alluring, all-tube sounds of the legendary Bill Putnam-designed 610 microphone preamp, with the signature FET compression of our 1176LN, to create the ultimate recording channel strip.

The warm, smooth tones of this mic preamp design — employed to record everyone from Frank Sinatra to Van Halen — and the unique characteristics of the compressor, are two major reasons why the 6176 is found in studios around the world.

Now You Can:

Record through the all-tube mic preamp derived from legendary Bill Putnam-designed 610 modular console

Compress signals with the 1176LN Class A FET compressor section — heard on countless hit records for more than 40 years

Use the "Split" or "Join" switch for separate or series operation of the preamp and compressor

Shape your tracks through vintage UA, "handmade in the USA," circuits

Two Classics in One

Two Classics in One

Thanks to its straightforward controls and hallmark sound, the 6176 is the signal path of choice for engineering heavyweights like Vance Powell and Joe Chiccarelli, plus artists including Chris Martin of Coldplay, Norah Jones, Wyclef Jean, and James Mercer of The Shins. The ability to “Split” or “Join” the preamp and the compressor sections via a simple switch gives the 6176 added flexibility. This is truly UA’s premier channel strip, and among the world’s finest.

The 610B — A World Renowned Mic Preamp

The 610B — A World Renowned Mic Preamp

The 2-610 microphone and instrument preamplifier has received praise from many corners. Michael Cooper, in his review for Mix Magazine, called it "hands-down, the most dimensional mic preamp I've ever heard". Peter Wade, engineer/producer who has worked with acts ranging from Wyclef Jean to Jennifer Lopez, said simply, "This box rocks." The 6176 mic preamp sections maintains the quality and character of the 2-610 while adding high-tension power regulation for improved bass response and a front-panel 15db pad switch.

The 1176LN — A Compressor with Tone

The 1176LN — A Compressor with Tone

As legendary engineer/producer Andy Johns put it, "The 1176LN is the workhorse compressor." In fact, the 1176LN may well be the most loved compressor in history. Its trademark lightning-quick attack and release times and the tone of it's Class A output amplifier have enhanced countless recordings over the last thirty-five years. We've recreated the 1176LN for the compressor section of the 6176 with the same exacting, attention to detail and tradition we use on our 1176LN. The resulting character, heritage and tone simply cannot be found on other channel strips.

What can I say?

It lives up to its legend and then some. Every studio big and small should have this piece. I've used it for several applications and its never failed to impress.

You don't have one? Just buy it. Now!

6176 Vintage Channel Strip

This unit would be an asset to anyone's sonic arsenal. There are channel strips with tube based overtones (which this has in spades), channel strips with transformer based overtones, and channel strips that pacify those who desire a pristine uncolored path. No one unit does it all, but this amazingly three dimensional tube preamp also has the benefit of being chained with THE desert island compressor, the 1176. If you are unfamiliar with this glorious piece of magic, just read any article about its fans who have used it on countless recordings, in all genres. I personally have used this unit for: vocals, guitars (acoust/elect) drum room, DI for bass-very delicious, dobro, mandolin, banjo, horn sections. It never disappoints. Enjoy!

My precious! Needs time to get used to, but absolutely great!

A bit muddy as a PRE, but this can be fixed by replacing stock tubes, especially that guitar JJ one. Great fast attack/release compressor! Fabulous for anything if you feel the device and set all the levels right! Much quicker than LA-610, but also requires you to have minimum attack/release understanding to start using it properly. It has a very musical tone and when coupled with the right microphone/converter gives a great result! I love the join/split feature and it has one of the biggest displays of all similar units. I love it and I dont want to let it go ever!

Creamy Vocal Pre!

The 6176 has been my go-to vocal recording box since my original purchase in 2003 (I have serial number 349). It's clean, but not pristine or boring. The 1176 portion is classic and helps when tracking as well as mixing. I may add other favors, but I'll never, ever stop using my favorite vocal recording pre amp, the 6176.

just amazing! what's in your head comes out through it, with more effort and character, things that you normally don't get from a machine, 'coz the 6176 is a human way of thinking, well I'd say ...of sounding!

Wow, what sonic joy! I recorded a Strat direct to a track using the 6176. I sent that out to a Rivera Quiana, tweaked the sound at the amp, set up an AT 4033 in the sweet spot, plugged the mic into the 6176 then recorded that to another track. Great sound and so much fun! I would buy it again in a heartbeat. Thanks UA for making great products.

Thank you UA.

Dear Uaudio,
I purchased the 6176 as part of the deal which included the UAD-2 Quad card. I use a Mindprint DTC and Vintech X73i for audio tracking at present. The 6176 is just better as a single channel. I love the EQs on the Mindprint and the X73i, but the combination of the mic pre and 1176 compressor on the 6176 just is better for a class sound and fast workflow when tracking. That said, I can take the outs from the other strips into the compressor of the 6176 with ease.
The 6176 is top top class sound equipment- a make everything sound better box. A Rolls Royce in my project studio. Result!

I love this channel strip! The 610 PRE really makes many of my mics shine, whether a LDC Valve, ribbon or condensor, and with gain staging you can vary the color and there's plenty of head room. The 1176LN is just amazing and I have several go to settings I've come to rely on. Being able to pair or split the 610 and 1176LN is a Godsend. I also use the DI frequently for electric bass. There will always be a spot on my rack for the 6176!

The most flexible and useful box I have! Tracking, mixing, and coloring--it's all here. I especially enjoy being able to "decouple" the devices so I can use the 610 as a tone box for one track while compressing another! Now I just need another one to link!

I received my 6176 one week ago. So far I've tested it on El-guitar and Vocals. I use it to record into Logic on my Mac Pro. I think this unit really flexible and versatile. On the Pre-amp section it's a little risky to get to much distortion on the Peaks. I have own a LA-610 for a while and learned to keep the levels down before the signals gets into the Compressor section. Some claims that there is not enough headroom on the Pre-amp, but I believe they set the Level to high out from the Pre-Amp section. It's in the compressor section where this unit really shines! It can really pick out the best bite from the El-guitar, and get your vocal right "in-your-face" in the "All-Button-Mode. I can be quite smooth as well if you want to. But I prefer the LA-610 for "soft" vocals. It's definately worth the time to play around with different settings and test over and over again, because it can really sound wonderful! This unit is really Rock 'n' Roll!

Oh man!! How I love my 6176. The joy of a 610 and an 1176 together. Smashing combo!

I never expected this box to be such a versatile tone shaping unit. I almost double my mic count with certain type mics, like ribbons and some dynamics thanks to the impedance switch. And slightly compressing going in does absolute wonders to anything I put through it, everything just hits its spot in the mix.

It can be tricky to dial in at first, but once you get the hang of it... WOW !!

Love it !! Cheers UA!

I have owned the UA 6176 since 2008 and, even with a number of other preamps in the rack, this one is used on every project! The joining of the creaminess of the 610 preamp and the transparent (and when you need it, not so transparent sounds from the 1176 make this a must have for any serious studio. SOmetimes I feel as if I should purchase another for back-up...just in case!

M. Schober

All I have expected and more... pretty flexible. Due to the split function you have two decent pieces of gear in one box. I'm in love.

I use this unit (I actually have two!) every time I track. Today they were used on acoustic guitars to make them sit in the track right where they needed to be. AND on a wurlitzer track to make it match up with the punch of the electric guitar. I can't imagine not having them available when I need them!
