A tube tone filled preamp meets the quick and predictable control of a classic 1176 compressor, what's not to love?
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.
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.
