Founded in 1981 by Bill Fitzsimmons, Jan Sandri, and Charles Rodriguez, FSR was established to fill the AV industry’s need for control modules and subsequently expanded with a suite of metal products specifically addressing the AV market. Charles, then owner of AV Services, a NY/NJ-based AV integration company, partnered with the extremely talented engineer Bill Fitzsimmons and Jan to design, manufacture, and market dissolve units, power modules, relay controllers, audio attenuators, and more.
