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 built for sound operators managing permanent installations in venues, houses of worship, retail spaces, and other facilities where silent, dependable operation matters. Its 1U rack footprint and integrated amplification eliminate the need for external amps—everything you need for mixing and powering speakers lives in one unit that won't hum or draw attention in quiet environments.

Amplification & Power Distribution

Two 40-watt amplifier channels drive the mixer's eight input channels with the reliability touring and permanent sound operators demand. The unit handles both 8-ohm and 4-ohm speaker loads and supports 70V and 100V distributed audio systems without requiring an external transformer, cutting down on gear, cable runs, and potential failure points during setup and teardown.

Control & Connectivity

Each of the eight channels gets independent volume control, with master volume, bass, and treble controls to shape the overall mix. Balanced mic/line connectors and unbalanced RCA jacks cover your input needs; speaker outputs and RJ45 connectors for CSR-V in-wall volume controls let you place remote control stations throughout a venue or facility, giving you flexibility in how operators and venue staff manage zones and levels from different locations.
