JBL NCSMA2120-U-US Commercial Mixer/Amplifier

The NCSMA2120-U-US is a compact, fanless 1U rack-mount mixer-amplifier designed for commercial installation and distributed audio systems. Its efficient Crown DriveCore technology delivers substantial power in a minimal footprint, making it ideal for retrofit projects, background music systems, and small-to-medium venue audio.

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.

Control & Efficiency

Individual volume controls for each channel, independent master volume adjustment, and dedicated bass and treble controls give operators precise sonic shaping across the system. The universal power supply accepts 100–240 VAC at 50/60Hz, eliminating voltage compatibility concerns in diverse installation environments.
