JBL NCSM14-U-US Compact Audio Mixer
The NCSM14-U-US is a compact, fanless mixer engineered for fixed recording installations and networked studio environments. Its shallow 1U half-rack footprint and lightweight construction fit seamlessly into control rooms, live tracking setups, and distributed recording spaces where silent operation and reliable signal management are essential.
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 into existing studio rigs without acoustic noise or thermal concerns. The black finish and minimal footprint keep it visually neutral in any recording environment, while the universal power supply (AC 100–240 VAC, 50/60 Hz) enables portable and multi-room studio configurations.
Audio Performance & Connectivity
The 4 input / 1 output configuration provides clean signal routing with frequency response of 20 Hz to 20 kHz ±1 dB, preserving full-spectrum fidelity for mixing and monitoring. 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 removes unwanted low-frequency rumble during tracking and playback.
