JBL NCSMA2120-U-US Commercial Mixer/Amplifier
The NCSMA2120-U-US is a compact, fanless 1U rack-mount mixer-amplifier purpose-built for venues, installations, and live sound systems that need reliable amplification without excess heat or noise. Its efficient Crown DriveCore technology delivers substantial power in a minimal footprint, making it essential for touring support systems, fixed installations, and small-to-medium venue reinforcement where dependability matters.
Power & Connectivity
This unit generates 240W RMS output power with the capacity to drive 8 ohm and 4 ohm loads, as well as 70V and 100V distributed audio systems without requiring a separate transformer. Eight mixer-channel inputs with balanced mic/line and unbalanced RCA options, combined with RJ45 connectors for JBL CSR-V in-wall volume controls, provide flexible routing for multi-zone installations and remote level management from the stage or FOH position.
Control & Efficiency
Individual volume controls for each channel, independent master volume adjustment, and dedicated bass and treble controls give sound engineers precise sonic shaping and real-time response across the system. The universal power supply accepts 100–240 VAC at 50/60Hz, ensuring compatibility whether you're running a permanent install or loading gear into different venues worldwide.
