CSA1300Z [Open Box]

The JBL CSA1300Z is a single-channel, 300W commercial amplifier built for distributed 70V and 100V sound systems in restaurants, retail stores, offices, and other commercial spaces. Crown's DriveCore technology sits at the center of the design, replacing up to 500 discrete parts with a single chip that cuts down on points of failure while holding onto clean, reliable output. Both 70V and 100V operation come built in, so the amplifier powers a full run of tapped speakers without an external step-up transformer, and a 2RU rack design keeps a server closet or AV rack from filling up with gear. A sleep mode disable function keeps the amp always live for paging or scheduled announcements, and illuminated control rings make level settings easy to read even in dim equipment rooms. RJ45 connectors let it pair with a JBL CSR-V wall volume controller over standard CAT5 cable, giving front-of-house staff a simple way to adjust levels without touching the rack. Harman's GreenEdge efficiency work also means the amplifier draws less power at idle and under load than older analog designs, so it pays back part of its cost in energy savings over time.
