UA Channel Strips

6176

Advances in digital recording technology are providing users with tremendous power and flexibility for increasingly less money. All too often, however, the audio quality of these systems is limited by their input stages. Many users who demand the power and flexibility of today’s recording technology find themselves yearning for the warmth and tone of yesteryear’s hand-built analog circuitry. Now with the release of the 6176, Universal Audio, for the first time, combines their highly acclaimed 610 tube microphone preamp with their legendary 1176LN compressor to create the ultimate single channel signal path for everything from vocals to vibraphones.

610B Mic Pre
The 2-610 microphone and instrument preamplifier has received praise from many corners. Michael Cooper, in his review for Mix Magazine, called it “hands-down, the most dimensional mic preamp I've ever heard…” Peter Wade, engineer/producer who has worked with acts ranging from Wyclef Jean to Jennifer Lopez, said simply, “This box rocks.” The 6176 mic preamp sections maintains the quality and character of the 2-610 while adding high-tension power regulation for improved bass response and a front-panel 15db pad switch.

1176LN Limiting Amplifier
As legendary engineer/producer Andy Johns put it, “The 1176LN is the workhorse compressor.” The 1176LN may well be the most loved compressor in history. Its trademark lightning-quick attack and release times and the tone of it’s Class A output amplifier have enhanced countless recordings over the last thirty-five years. We’ve recreated the 1176LN for the compressor section of the 6176 with the same exacting, attention to detail and tradition we use on our 1176LN. The resulting character, heritage and tone simply cannot be found on other channel strip units.

LA-610

The LA-610 brings UA’s legendary vintage "all tube" luxury sound into a modern channel strip format by combining the 610 Mic-Pre/EQ/DI section and a T4 Opto-compressor into a single 2U unit with a ground-breaking price.

The 610-tube preamp,DI and EQ is from UA's TEC award winning 6176 and is based on the legendary console modules developed by Bill Putnam in the 60's. Countless classics have been recorded using these preamps, noted for their musical character and warmth.

The simple operation and program dependent nature of the LA-610 T4 compressor provides the same extremely musical control that has made the LA-2A such a well-loved classic for over 40 years.

The LA-610 packs tremendous sonic versatility and is an ideal front-end for tracking with modern DAW’s and the serious project studio looking to get the UA sonic experience : real quality and character at an accessible price.

In collaboration with Dennis Fink, one of the original UREI® analog design engineers, the LA-610 was carefully designed to deliver the essence of the “LA” sound but without the costs of being an exact LA-2A component clone. The LA-610 uses three 12AX7A’s, a single 6072A and a single 6AQ5 tube for amplifier warmth and overall tonal balance.

After the preamp section, the LA-610 offers a new T4 optical compressor. The electro-optical detector or "T4 cell”, is the very heart and soul of the Teletronix LA-2A. The unique combination of electroluminescent panel and photo-resistors inside the T4 cell are the crucial circuit components that give both these compressors their signature sound.
