JBL NCSM14-U-US

JBL NCSM14-U-US Commercial Audio Mixer

The NCSM14-U-US is a compact, fanless mixer built for fixed installations in commercial audio environments. Its shallow 1U half-rack footprint and lightweight construction make it ideal for wall-mounted or tight-space deployments where reliability and simplicity matter more than feature bloat.

Design & Build Quality

Built as a fanless unit measuring just 8.6" W × 11.9" D × 1.7" H and weighing 4.41 lbs, this mixer integrates seamlessly into existing installations without acoustic noise or ventilation concerns. The black finish and compact footprint keep it visually discrete in any commercial setting, while the universal power supply (AC 100–240 VAC, 50/60 Hz) ensures global compatibility wherever you deploy it.

Audio Performance & Connectivity

The 4 input / 1 output configuration delivers straightforward signal routing with frequency response of 20 Hz to 20 kHz ±1 dB, ensuring transparent audio reproduction across the full spectrum. Input flexibility includes Euroblock mic/line connectors, unbalanced RCA inputs, and RJ45 connections for JBLCSR-V in-wall volume controls, while 27 VDC phantom power supports condenser microphones and the 70 Hz high-pass filter switch keeps low-frequency rumble and HVAC noise out of your mix.
