JBL Commercial Series Amplifiers (CSA) go well beyond the expected in generating powerful sound. From the switch-mode universal power supply to the efficient performance of Crown's DriveCore Technology, JBL continues to set new standards in commercial power amplifier technology.

Simple to configure, the CS amp provides a DriveCore-based sound solution. This replaces up to 500 parts with one small chip, significantly reducing the part count and increasing reliability while maintaining superb performance.
