6176 Vintage Channel Strip
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
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 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
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.

    A new Color to my sound
    by C. Posada(Thursday 22 September, 2016)

    Just turn up the level knob if you need hot classic tube sound. Very musical with great harmonic distortion. But if you need it to be clean, you can do it definitely. Always has its own color that I really love. This preamps is not my first choice for very detailed acoustic instruments,… Read More

    Does everything it says it does....
    by A. Lein(Thursday 16 June, 2016)

    It's great to have a good front end for tracking everything. This is it. As primarily a vocal or guitar tracker for me, it's very easy to use (at the same time, it can be a tough one too) and sounds great. I try to find a middle ground on the pre into the compressor and then let it be… Read More

    Gorgeous in every facet.
    by E. Foshee(Tuesday 17 May, 2016)

    Were it legally or physically possible I would marry my 6176. She would have to be willing, of course, but I'd do it. That being said, I could not find a single complaint about this piece of hardware and the beautiful sounds that emanate from my monitors as a result. If you're unsure about… Read More

    This is my favourite!
    by G. Jackson(Saturday 20 February, 2016)

    This gear makes me speechless. I think its the 1176 compression on the unit that really makes it stand out and the tones are just amazing. The pre is excellent but the fact that you can use another pre then throw the 1176 into the mix is fantastic. Love this unit! Read More
