Engineered for reliable, low-maintenance performance in AV and security environments, the JBL Professional CSA 1120Z 1-Channel 120W Power Amplifier delivers clean, dependable audio for paging, background music and surveillance speaker arrays. With a robust 120W RMS output and built-in 70V/100V support, the CSA 1120Z removes the need for external transformers and speeds installation across multi-zone systems. Its fanless, space-saving 1U rack design operates quietly in monitoring rooms and control centers, while DriveCore™ technology and Energy Star certification keep energy use and operating costs low.

Network-friendly features include Ethernet control and RJ45 support for JBL CSR-V in-wall volume controllers, enabling centralized volume management for security and surveillance deployments. A universal power supply (100–240 VAC) simplifies global rollouts and the amp’s durable design is backed by a 3-year limited warranty for long-term confidence. Ideal for integrators and system specifiers, the CSA 1120Z streamlines installation and reduces total cost of ownership for commercial, retail and security AV projects.
