The JBL's CSA180Z audio amplifier 1x 80W provides a small and powerful amplification option. To produce stable and efficient sound amplification, the machine uses a universal switch-mode power supply and Crown's DriveCore technology. Out of the box, the unit works with both 70 and 100 volt systems. It comes with one RJ45 connector for use with the CSR-V in-wall volume controls from the firm. Mono sum RCA connections and Euroblock are used as inputs. Euroblock connectors are used to give outputs. Visual feedback is provided by illuminated knobs, and the amplifier can handle AC voltages ranging from 100 to 240 VAC, 50/60 Hz, thanks to the universal power supply. The amplifier also contributes to HARMAN's GreenEdge sustainability project.
