The AmPlus 100 business music amplifier has front end processing permitting the connection and level adjustment of two sources: left/right or source A/source B. Power hookup, remote volume hookup, line output connections, and provision for bass adjustment are provided on the rear panel.Option card accessories offer the freedom to add additional sources,paging, or active equalization. Source or paging cards may be plugged into option card slots provided on the rear panel.Active equalization can be implemented by removing the chassis cover and connecting the equalizer card directly to the power amplifier.
