Universal Audio

The classic studio limiter!

The original Universal Audio 1176LN designed by Bill Putnam was a major breakthrough in limiter technology-the first true peak limiter with all-transistor circuitry offering superior performance and a signature sound. Evolved from the popular Universal Audio 175 and 176 vacuum tube limiters, the 1176LN retained the proven qualities of these industry leaders and set the standard for all limiters to follow.

Today, the 1176LN is new again. While it certainly would have been possible-and much simpler-to modernize and "improve" the 1176LN, Universal Audio made every effort to remain faithful to Putnam's design and intentions. Carefully trained staff hand-wire and test each unit to uncompromising standards. This version of the 1176LN captures all the nuance of the original through obsessive attention to detail and delivers that trademark sound. Demand the original. Accept no copies.

  • True to the original in design, manufacture, and performance
  • Modeled after 1176LN blackface, D and E revisions
  • F.E.T. gain reduction
  • Pushbutton selection of compression ratios: 4:1, 8:1, 12:1, 20:1
  • Ultrafast attack time”20 microseconds to 800 microseconds
  • Adjustable release time”50 milliseconds to 1.1 second
  • Class A line level output amplifier
  • Custom-built Putnam-designed output transformer
  • Stereo interconnect operation

Still the first-call choice of professionals for tracking vocals, guitar, and drums. Give your music the punch and character it deserves with a Universal Audio 1176LN.
