The NCSMA2120-U-US is a compact, fanless 1U rack-mount mixer-amplifier engineered for multi-room recording setups, small studio installations, and distributed audio environments. 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 for Flexible Recording Scenarios
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, enable flexible source management across multiple recording zones and monitor feeds.
Mixing & EQ for Session Control
Individual volume controls for each channel, independent master volume adjustment, and dedicated bass and treble controls allow precise frequency shaping and level management during recording and playback. The universal power supply accepts 100–240 VAC at 50/60Hz, ensuring stable operation across different studio environments and international setups.
