Euphonix was an American professional audio engineering company based in Mountain View, California. Euphonix produced the first successful line of large, digitally controlled analog audio mixing consoles in the late 1980s and has since expanded into all-digital systems. In 2010, the company was acquired by Avid.

Euphonix' entry into the professional audio market implemented technology that significantly improved the working methods and economics of music production and production of sound for film and television. Euphonix's radically new design won several industry awards.

Euphonix's approach of using digital logic to control multiple analog signal chains can be traced back to the original ideas of Scott Silfvast. Working at Stanford Research Systems (SRS) by day, he developed the initial concepts for Euphonix's first product, the Crescendo, by night. Mechanical designer Adam Reif, also employed by SRS, joined Scott in 1988 and founded Euphonix in a garage behind Scott's house in Palo Alto.

Initially, Euphonix was privately funded. Many early investors were the friends and families of employees. As payroll and burn rates increased, private investment was secured. Industry veterans were hired as the company outgrew the garage and moved to a larger building under the same roof as Fry's Electronics in Palo Alto, California.     In April 2010, Euphonix was acquired by Avid. This allowed the company to continue as a premium provider of audio electronics for a variety of other industrial sectors to this day. (Source: Wikipedia)
