About the JBL CSA280Z CSA 280Z Audio Amplifier (2 x 80W)

The JBL NCSA280Z-U-US is a professional, multi-channel commercial audio amplifier engineered for distributed sound and paging systems in commercial installations such as offices, retail stores, restaurants, schools, and transportation hubs. Part of the CSA Series, this model delivers two channels of 80 watts each into 4-ohm loads, with full support for 70V and 100V constant-voltage operation, making it highly versatile for driving multiple ceiling or outdoor speakers across large zones.
