Jbl CSA140Z

40-watt single-channel power amplifier from the Commercial Series. Combining years of innovation, invention, and insight from HARMAN brands, JBL Commercial Series (CSA) amplifiers go far beyond expectations in delivering powerful sound. From the universal switching power supply to the efficient performance of Crown's DriveCore technology, we continue to set new standards in commercial power amplifier technology. Easy to configure, the Commercial Series amplifier provides a DriveCore-based audio solution. This replaces up to 500 components with a single small chip, significantly reducing the number of parts and increasing reliability, while maintaining exceptional performance. Supporting 70 V and 100 V installations, the Commercial Series amplifiers include RJ45 connectors for use with JBL CSR-V wall-mounted volume controls. Its universal power supply allows each amplifier in the Commercial Series to accept AC voltages ranging from 100 to 240 VAC, 50/60 Hz. And with HARMAN's GreenEdge environmental initiative, the Commercial Series amplifiers quickly pay for themselves through energy savings.
