Universal Audio 1176LN Classic Limiting Amplifiers (Pair) + 1176-SA Stereo Adapter Bundle

OVERVIEW

The Universal Audio 1176LN Classic Limiting Amplifiers (Pair) + 1176-SA Stereo Adapter Bundle delivers one of the most iconic stereo compression solutions ever created. Combining two hand-wired 1176LN Classic Limiting Amplifiers with the faithfully recreated 1176-SA Stereo Adapter, this bundle provides everything needed to operate the legendary compressors as a perfectly calibrated stereo pair. Whether used for stereo tracking, drum buses, mix bus compression, or mastering, it delivers the unmistakable speed, punch, and analogue character that have made the 1176 an industry standard for decades.

Originally designed by Bill Putnam, the 1176LN revolutionised dynamics processing as the world’s first true peak limiter built with all-transistor circuitry. Renowned for its lightning-fast attack times, musical compression, signature transformers, and famous “All-Button” mode, the 1176 continues to shape countless professional recordings across every musical genre. Every unit is meticulously hand-built and tested to preserve the sound and performance of the original design.

Completing the package is the authentic 1176-SA Stereo Adapter, allowing both compressors to function as a precisely matched stereo system. Compatible with both vintage and current-production 1176LN units, the adapter features gold-plated RCA connections, a rugged shielded metal chassis, and reliable long-life battery operation. Together, these three components provide an elegant, professional stereo compression solution that remains one of the most respected dynamics processing chains in modern recording.
