Technology Developer and Teacher Saul Walker to Be Honored at NYU Event

The life and professional legacy of the late API co-founder Saul Walker will be honored at a celebration to be held at 10:30 a.m. on Sunday, February 12, 2017, at New York University’s Kimmel Center for University Life.

Walker, who passed away in October 2016, was revered in the audio community as the developer of API’s 500 Series plug-in modular equipment system of portable “lunch box” and rackmount equipment. The first module in the series, his 550A Equalizer has served as an industry gold standard for more than 40 years.

He also pioneered the application of op-amp technology in audio system design. Walker’s 2520 all-discrete op-amp provides a +30 dBm clip level (10 times the power of most audio ICs) and continues to be the mainstay of API’s product line, including his 512 Microphone Preamp and 560 Graphic EQ.

Walker began his career working for the U.S. Navy, as a developer of military electronics and rocket telemetry. In 1990, he joined Otari, where he engineered film-production consoles for facilities including Sony, Skywalker, and Universal. Late in his career, he became an adjunct professor at NYU in 2006; he taught electronics to undergraduate and graduate music technology students, who benefited from the vast knowledge he accumulated as a technology developer.

Walker’s legacy carries on in his students, and through the products he designed, which have been used by broadcast TV networks; professional and private music recording and mixing studios, and even The White House.
