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.

This thing just rocks!

I can honestly say this is the best £1800 I have ever spent on a channel strip.
You can get so many tones from it and the compression is second to none.

The build quality is rugged and when you play with the dials it feels solid.
I use it on everything.

Only down side is I wish I had another.

Well done UA :)

This is exactly what I was hoping for.
Warm and tube(y)sound. Full in character.
Makes everything come to life.
Brilliant on vocals and acoustic instruments,
but with a little bit of tweaking, you can make it work all over.

The 6176 actually adds that magic touch ...

has character, attitude...

as expected it has character and attitude. one of my go to pre for vocals but not only for recording also at mixdown i am routing some guitars, vocals or snare through the pre or compressor...split function is great so u can use the pre and comp independently.

i had the spl channel one mkII premium, was never really happy. the 6176 is a great match with my sony c37a tube mic.

My Rating is 10 not just 5.

It's my favorite preamp in the studio, good pre with some valve distortion, for acoustic guitars and vocal is just perfect. That's why we can hear Chris Martin's vocal and Adele's vocal with so softness sound.

Awesome pristine sound!

I need to be honest… i picked up this gear because i read that Adele uses it. At the beginning i had some troubles doing the setup connecting the 6176 with my apollo. After the help of the people from support i understood that i was needing a microphone that could help to get the best of this gear. The people from support really kindly suggested me the Josephson and since then the results of my recordings are blowing me away. Really amazing. I think that this is an amazing piece of gear, but your really need to have the right tools. Not for the aficionado…. for the one trying to become a pro!

I've used these for years in the studio. Several times in the their separate incarnations (the 610 and the 1176).

This is the real deal. You just have two classic pieces in one unit!

It will add life to any source its fed.

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.

I love it ! Anything i record through it sounds amazing ! Cant wait to buy another 6176
and a 2-1176. Universal Audio makes the best gear ! Also i love my UAD-2 Quad !
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!
