UNIVERSAL AUDIO / LA-610 MKII

A channel strip consisting of a preamplifier developed by Bill Putnam in the 1960s and designed based on the console module used in the records of famous artists, and an optical compressor that reproduces the LA-2A. Warm and smooth sound is still loved by many engineers and artists.

■ Channel strip

The A-610 MkII is a channel strip that integrates an all-tube vintage mic preamp that can be heard on albums such as Coldplay, Van Halen and The Beach Boys with a real Teletronix T4 optical compression circuit. With warm preamp tones and smooth, natural compression, this classic channel strip design is needed by modern users like true compressor bypass, large meters, high power and auto-switching power supplies.

The Legend 610 Preamp
The LA-610 MkII is based on the legendary console module i developed by Bill Putnam in the 1960s. Its character and warm sound are well known, and this preamp was used in recordings by many artists, from Frank Sinatra to Coldplay, Van Halen and Pet Sounds. The LA-610 MkII gives the source a silky vintage warm sound, similar to the design of the original console mic amp.

Tube compressor with your own tone
The LA-610 Mk II's T4 tube compressor offers the same very warm sound limiting as the Opt Compressor King, Teletronix LA-2A. The electro-optical detector, or “T4 cell,” is the heart and soul of the Teletronix LA-2A. Its photoresistor is an important circuit, giving the compressor a unique warmth and perfect for tracking vocals, bass and acoustic guitars. In summary, it's impossible to get bad sound with the legendary LA-610 MkII preamps and compressors.
