JBL Professional CSA2120 2-Channel 120W Power Amplifier

Built for reliable installed sound and security applications, the JBL Professional CSA2120 2-channel 120W power amplifier delivers consistent audio performance in a compact rack-mount package. Engineers and integrators benefit from two robust 120W channels (at 4/8Ω), a universal 100–240V switch-mode power supply and plenum-rated (UL2043) construction that supports safe installation in HVAC spaces common to commercial and surveillance systems. Its convection-cooled, fanless design keeps operation quiet in monitoring rooms and equipment closets while minimizing maintenance and failure points.

Flexible connectivity — including summing RCA inputs per channel — streamlines integration with control systems, NVRs, and paging interfaces for security, surveillance and facility monitoring. Auto-standby conserves energy when channels are idle, helping lower lifecycle costs across distributed AV and security deployments. Compact 2U height and light weight simplify rack planning and reduce shipping and installation time.

For integrators specifying audio for security, surveillance or corporate AV, the JBL CSA2120 provides dependable, low-noise amplification that’s easy to deploy. Add the CSA2120 to your next installed-sound or monitoring project to power speakers with confidence.
