The 6176 Vintage Channel Strip combines the captivating, all-tube sound 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 — used 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 worldwide.
