Description
The JBL NCSMA240-U-US packs a dual 40-watt, 8-channel powered mixer into a convenient 1U rack enclosure. Each channel boasts its own independent volume control, and there are volume, bass, and treble controls for each of the CSMA 240’s two master outputs. Its streamlined front panel is a breeze to use, and illuminated rings make it easy to see the controls in the dark. A bevy of balanced mic/line inputs, along with unbalanced RCA inputs and speaker connections enable you to use the CSMA 240 with nearly any source. You also get support for JBL’s CSR-V in-wall volume control (sold separately). Add to that compatibility with most sound reinforcement gear, and you’ve got a powered mixer that’s tailor-made for just about every commercial and industrial use you can dream up.
