JBL NCSMA240-U-US

JBL NCSMA240-U-US Dual 40-Watt 8-Channel Powered Mixer

The JBL NCSMA240-U-US is a compact, fanless powered mixer engineered for permanent installation in commercial and institutional audio systems. Its 1U rack footprint and integrated amplification make it ideal for spaces where equipment density and silent operation are critical—classrooms, boardrooms, houses of worship, and retail environments benefit from this all-in-one approach.

Amplification & Power Distribution

Two 40-watt amplifier channels drive the mixer's eight input channels, delivering reliable power without the noise of active cooling. The unit accommodates both 8-ohm and 4-ohm speaker loads and integrates seamlessly into 70V and 100V distributed audio systems without requiring an external transformer, simplifying installation and reducing component count.

Control & Connectivity

Each of the eight channels receives independent volume control, while master volume, bass, and treble controls shape the overall output. Inputs span balanced mic/line connectors and unbalanced RCA jacks; speaker outputs and RJ45 connectors for CSR-V in-wall volume controls enable multi-zone operation from discrete remote stations throughout a facility.
