JBL CSA 240Z Audio Amplifier (2 x 40W)

The JBL CSA240Z is a commercial power amplifier that delivers 40 watts on each of its two channels while supporting 70 volt and 100 volt speaker runs. This combination makes it an easy drop-in for distributed audio systems that need clear background music and reliable paging in cafés, classrooms, retail floors, or offices.

The chassis occupies just one rack unit and relies on convection cooling, so it stays silent and runs cool without a fan. That quiet operation lets you mount the amplifier in equipment closets, ceiling spaces, or media carts where noise and ventilation are limited.

Connecting sources is simple. RCA inputs accept music from a laptop, media streamer, or smartphone adapter, and euroblock connectors provide a secure link from professional mixers or paging stations. An RJ45 port pairs with the optional CSR-V wall controller over standard network cable, giving staff hands-on volume control from the floor without walking to the rack.

Built-in digital signal processing supplies equalisation, crossover, compression, and limiting, so loudspeakers can be tuned and protected without extra outboard gear. The universal power supply works worldwide on 100 to 240 volt mains, and Energy Star certification shows that the amplifier conserves power when audio is idle.

Front-panel knobs feature illumination for quick level checks in dimly lit booths or backstage areas, and a full 20 hertz to 20 kilohertz bandwidth keeps music warm and speech intelligible. Whether you are outfitting a new build or upgrading an existing venue, the CSA240Z offers a clean, efficient path to dependable day-to-day sound.
