"Today we say goodbye to our beloved founder, Dr. Bob Heil. Bob fought a valiant, year-long battle with cancer, and passed peacefully surrounded by his family. Bob’s impact on professional and live sound cannot be overstated. Driven by a lifelong passion for sound, Bob’s pioneering work revolutionized how concertgoers experienced live sound. Bob created and developed numerous pro sound innovations and products over the years, some of which are preserved in the Rock and Roll Hall of Fame Museum. In 2007, Bob was the recipient of the Audio Innovator Parnelli Award, recognizing his outstanding influence on the live sound industry. Countless artists, creators, broadcasters, podcasters, sound engineers, and sound professionals worldwide continue to be impacted by Bob’s work. While Bob’s presence will dearly be missed, we are immensely proud and happy to honor and carry on his legacy.”
