JBL NCSM28-U-US

JBL NCSM28-U-US Networked Control and Status Module

The NCSM28-U-US is a professional-grade control and mixing interface designed for installed audio systems and networked environments. This compact 1U rack unit delivers transparent audio processing with minimal latency, making it an essential component for commercial installations, conference systems, and distributed audio networks that demand reliability and clean signal management.

Audio Performance & Signal Integrity

The unit maintains exceptional audio fidelity across the entire audible spectrum with frequency response of 20–20,000 Hz ±1 dB and total harmonic distortion of just 0.05%. A signal-to-noise ratio exceeding 90 dB ensures clean audio paths even in noise-sensitive applications, while ±10 dB tone controls at 100 Hz and 10,000 Hz provide practical EQ adjustment for room compensation and source matching.

Connectivity & Installation

Eight independent inputs and two outputs accommodate flexible routing configurations using Euroblock connectors for balanced mic/line connections, unbalanced RCA inputs, and RJ45 connectors compatible with CSR-V in-wall volume controls. The fanless design and minimal 10W power consumption make this unit ideal for retrofit installations and spaces where acoustic silence is required.
