UNIVERSAL AUDIO / 1176LN

A limiter sound that is loved by many people both now and in the past. It is still a standard studio comp. From natural limiting to vocals and acoustic guitars, hard limiting distorted with INPUT and four-button pressing are the only sounds that can only be produced by 1176.

■ Compressor

Launched in 1967, the 1176 Limiting Amplifier offers incredibly fast attack and release times, a musical Class A output stage, and a wide range of sounds, from delicate and transparent compression to driven and distortion. Universal Audio's 1176 LN Classic Limiting Amplifier is a faithful reproduction of the original clear design developed by Bill Putnam Sr., can be said part of the history of audio used in recordings by Led Zeppelin, The Rolling Stones, Michael Jackson and others.

Rich tones, colorful compressors
The main selling point of the 1176 is the ultra-fast attack time, which is only 20 μS (.00002 seconds) at the fastest setting. This works great for all types of programs. However, the engineer soon realized that passing through that circuit in 1176 gave him a character and a vibe. Some engineers used the 1176 with compression turned off to get that distinctive tone. The unit's amps and transformers add "hot" quality to all the sounds that pass through it.

B-Daman Rebirth
When Bill Putnam, Jr. rebuilt Universal Audio in 1999, it was the company's first product to recreate the Blackface 1176 LN. Relaunched in 2000, it was designed based on the classic 1176 revisions C, D and E. One of the most important aspects of reproducing the sound of the original hardware is to increase the number of windings on the final lineout amp circuit that provides the feedback signal to faithfully reproduce the original output transformer. It was. Bill Putnam Jr. found a wide range of design notes that could reproduce and improve his father's original design.

Push Button Magic
One of 1176's most famous features is that you can push-button ratios from 4: 1 and 8: 1 for compression and 12: 1 and 20: 1 for limiting. You can make a wide range of settings from 4: 1 to 1176 to "all button" mode where all ratio buttons are pressed at the same time. This allows you to achieve a unique sound that cannot be heard on other processors. With a stable slope and lag time that responds to early transients, distortion increases, creating a confusing sound with room mics on drums, and focusing on bass, electric guitar, or can place vocal sounds to the center of the mix.

The only irreplaceable existence
