JBL CSA280Z Dual 80W Professional Amplifier 70V / 100V / 4 Ohm

The JBL Commercial CSA series of amplifiers are professional tools with a sleek industrial look, designed and built for demanding commercial sound applications. The latest DriveCore technology from Crown is built in, which significantly reduces size and weight, and all amps are highly efficient, fanless, and simple to install and operate.

The CSA280Z offers unmatched ease of use, with a clean front panel featuring only master volume adjustment, adjustable bass and treble controls and a power switch. All the volume controls are surrounded by an illuminated ring, making them easy to see and operate in darkened environments. The amplifier can drive 8 ohm and 4 ohm loads and can be used with 70V and 100V distributed audio systems without the need for a separate transformer. In addition to balanced mic/line input, unbalanced RCA inputs and speaker connections, all units include RJ45 connectors for use with JBL CSR-V in-wall volume controls. All models feature a universal power supply which enables the ability to accept AC voltages from 100 to 240 VAC, 50/60Hz, and a selectable Sleep Mode feature which puts the amp into a hibernation status when no signal has been received for approximately two hours, greatly reducing power consumption. The amp immediately responds as soon as signal is reintroduced.

JBL Commercial amps are manufactured under Harman’s GreenEdge™ environmental initiative, conforming to lead-free RoHS standards and utilizing recycled copper, aluminum and steel, an energy-saving powder coat finishing process and other environmentally-conscious manufacturing processes. Their highly efficient design reduces power consumption and yields much more efficient operation – up to 80 percent more efficient than previous designs.
