The TOA BG-2120 is 120W Mixer/Amplifier. It is a total redesign of the highly successful BG-1000 Series and not just for design's sake. We spoke with our customers, who told us exactly what they wanted in a commercial background music & paging amplifier. We responded with a newly engineered chassis, designed to not only look better, but perform better and most of all-install easier. Starting with removable euro-block connectors to make wiring a snap, we added assignable MOH/Second Zone source assignment and provided access to mute priority and other settings via rear panel DIP switches - no more “popping the top”. Lastly, we've upped the power to 35W on the lower end model. Of course, we kept all the good stuff-solid, reliable performance for which TOA has been renowned.
