Universal Audio 1176LN – Classic Limiting Amplifier


Universal Audio 1176LN Classic Limiting Amplifier



The 1176LN Classic Restricting Amplifier is a modern-day recreation, yet every effort was made to stay sincere to UA creator Bill Putnam Sr.’s lofty layout and intentions. The original UA 1176LN was a major development in limiter modern technology– the very first real peak limiter with all transistor circuitry giving first-rate efficiency with a signature noise– and set up the criterion for all limiters to follow. The ultra-fast strike time and trademark noise have actually enticed fabled musicians and studio moguls identical to the 1176LN– Peter Frampton, Joe Satriani, Joe Chiccarelli, Vance Powell, and Robert Elizondo are just a few names on a list that’s continued to increase, for nearly FIFTY years.
