JBL NCSA280Z-U-US
Description
JBL NCSA280Z-U-US Compact Networked Amplifier
The NCSA280Z-U-US is a compact 1U half-rack amplifier engineered for networked studio systems and fixed installations where space efficiency and thermal reliability are essential. This fanless design delivers clean, efficient amplification without the heat management concerns of traditional Class AB circuits, making it exceptionally stable in sealed or temperature-sensitive studio environments.
Amplification & Power Delivery
Rated at 2 x 80 watts per channel, this amplifier drives 4-ohm, 8-ohm, 70V, and 100V configurations with a single unit, eliminating the need for multiple amps in flexible monitoring and playback scenarios. Input sensitivity of 1.4Vrms at 8-ohms and impedance options of 20K or 50K ohms ensure compatibility with a broad range of interface outputs and loudspeaker loads across mixed studio setups.
Design & Integration
Built on DriveCore technology, this amplifier consolidates approximately 500 discrete components into a single integrated chip, dramatically reducing component count and potential failure points. The inclusion of RJ45 connectors for JBL CSR-V in-wall volume controls, plus illuminated control knobs and a rack-mount kit, enables seamless integration into networked monitoring and playback systems with professional-grade gain management.
