MK II Tube Recording Channel Tube Mic Pre and EQ

LA610

Overview

The LA-610 by Universal Audio defined the affordable, ultimate vintage tone channel strip. So how can UA improve on tonal perfection on what was already a hit product? Enter the sequel...LA-610 Mk II, a second-generation revamp of the original 2005 LA-610 design. While the preamp and compressor are identical to the original LA-610 that professionals have come to know and love, additional features have been added such as true compressor bypass, larger metering, improved output signal, and an auto-sensing power supply. The LA-610 Mk II also features the highly popular black-on-black cosmetics of the LA-610 Signature Edition.

The original UA 610 tube mic pre and EQ have been used to record artists ranging from Frank Sinatra to Eddie Van Halen. It's a sound that never gets old - just better - thanks to the spirit of Bill Putnam and modern advances in electronics design.
