Description
JBL NCSA2120Z-U-US Compact Network Power Amplifier
The JBL NCSA2120Z-U-US is a half-rack, fanless amplifier built for installed audio systems where space and silent operation matter most. Its compact 1U footprint and fanless design make it ideal for mounted installations in venues, conference spaces, and fixed installations, while its robust power delivery handles both small and mid-size speaker loads without compromise.
Power & Amplification
Dual 120-watt output channels deliver 120W @ 4/8 Ohms with THD+N below 0.5%, providing clean, distortion-free amplification across standard impedance loads from 2–16 Ohms. The integrated Crown DriveCore technology replaces hundreds of discrete components with a single advanced chip, reducing complexity while maintaining transparent audio reproduction.
Installation & Connectivity
Balanced and unbalanced RCA inputs, Euroblock connectors, and two RJ45 connectors for JBL CSR-V volume control compatibility streamline integration into networked audio systems. Universal AC power acceptance (100–240 VAC, 50/60 Hz) and native support for both 70V and 100V installations ensure compatibility across diverse venue requirements.
