The JBL Commercial Series Amplifiers (CSA) integrate Crown’s DriveCore Technology with a switch-mode universal power supply to deliver amplified audio output. The DriveCore technology consolidates multiple components into a single chip, reducing part count and enhancing system reliability. These amplifiers are compatible with both 70V and 100V distributed audio systems and feature RJ45 connectors for integration with JBL CSR-V in-wall volume controls. The universal power supply supports AC input voltages ranging from 100 to 240 V at 50/60 Hz frequency. The design also incorporates energy-efficient features aligned with HARMAN's GreenEdge initiative.
