Single-channel 300W amplifier from CSA series that goes well beyond the expected in generating powerful sound and combines years of innovation, invention and insight from HARMAN brands. Simple to configure, it 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. The efficient performance of Crown's DriveCore Technology continues to set new standards in commercial power amplifier technology. Supporting 70V and 100V installations out of the box, this amplifier includes RJ45 connectors for use with JBL CSR-V in-wall volume controls (via CAT5 cable). And with HARMAN's GreenEdge environmental initiative, it quickly pays for themselves in energy savings. The amplifier further features space-saving 2 RU design, Sleep mode disable function and sleek industrial look with illuminated rings which make knobs easy to see and use.
