JBL CSA1300Z Single-Channel 300-Watt Amplifier

By combining years of innovation, invention and insight from HARMAN brands, JBL Commercial Series Amplifiers (CSA) go well beyond the expected in generating powerful sound.

The efficient performance of Crown’s DriveCore Technology 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.

Supporting 70V and 100V installations out of the box, CS amps include RJ45 connectors for use with JBL CSR-V in-wall volume controls.

And with HARMAN’s GreenEdge environmental initiative, CS amps quickly pay for themselves in energy savings.
