Universal Audio 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.
