The 1176 section stays true to UA's original 1176LN design and maintains all the same features, but with the addition of high-tension power regulation for improved bass response and a front-panel 15 dB pad switch. The 610 section offers Mic, Line and hi-Z inputs, and two bands of shelving EQ.

Split or Join -- It's Up to You

What do engineers like Joe Chiccarelli and Vance Powell, and artists/groups like Norah Jones and the Shins have in read more common? They all use the 6176. Offering a flexible, single-channel signal path, the 6176 combines a recreated 1176 with one channel of the 610 mic pre. By flipping a switch for Split and Join modes, you can split the 6176 Vintage Channel Strip into its two parts (preamp section and compressor section), or you can join them as a complete channel.

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.

610B Mic Pre

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.

1176LN Limiting Amplifier

As legendary engineer/producer Andy Johns put it, "The 1176LN is the workhorse compressor." 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. UA has recreated the 1176LN for the compressor section of the 6176 with the same exacting, attention to detail and tradition used on the 1176LN. The resulting character, heritage and tone simply cannot be found on other channel strip units.

The problem with writing a review like this is that you can’t describe musical experiences in words. But I thought it might interest some people like me to hear my 6176 story. People like me, that would be singer-songwriters who record themselves at home. Does a $3000 expense really make sense for someone like that? Of course not. I have read and dreamed about this device for over a decade. I’ve watched all the YouTube reviews, googled the term “affordable alternative” a hundred times without success. I’ve also spent a few hundred bucks on plug-ins that promised to recreate the magic. Can they? Who knows! I guess the most honest answer is that a first rate engineer could coax the 6176’s sort of complexity out of a few pieces of software after a long, tedious process of tweaking virtual buttons. In other words: For a simpleton like me with limited time it amounts to a crapshoot. A few times I thought I had “it”, then it was gone again. Enter an unexpected little windfall, three glasses of Malbec, and you got yourself a late night impulse buy. (What really made me go for it is zZound’s interest free installment plan, to be perfectly honest.) And now I have “it” at my fingertips, packed in a shiny, heavy, solid box with those impossibly cool huge dials. What is “it”? I can’t describe it in technical terms. Let me give it a shot in musical terms, then. The 6176 sort of holds you. It catches you. It props you up, makes you feel like you can do no wrong. read more Especially as a singer. It controls the dynamics of your voice in such a way that you find yourself whispering or belting, feeling in control in both instances. And everything in between. That overused word “warmth” seems to be the only apt one to really describe what this tube preamp achieves. It’s similar to what happens to your voice toward the end of a gig, when you’re nice and loose, and it all becomes effortless. There’s a bit of grit, or a lot of it, if you so chose. The very simple EQ does all you need to do, given you’ve found the perfect mic for your purposes. In my case, that’s a U47 clone, or sometimes a simple 57. The compressor is a legend for good reason. I keep the ratio low, the attack fast and the release pretty quick as well. That’s all I need. In closing, the answer to the question whether you’ll be happy or not about dishing out the big money on something your interface can, in theory, already do … depends. It depends on how much of your idea of hearing music is really about FEELING music. Depends on how sensitive (or crazy? Or both?) you are. Depends on whether or not the rest of your rig, especially the mic, is already perfect for what you need. Depends on your years of experience. Guitarists know that there are magical guitars out there, instruments that make you play better. Well, this is like that.
