JBL NCSA1120Z-U-US

JBL NCSA1120Z-U-US Compact Network Amplifier

The JBL NCSA1120Z-U-US is a compact, fanless 1U half-rack amplifier engineered for installation in professional audio systems where space and reliability are paramount. Built on Crown's DriveCore technology, this unit delivers consistent performance in commercial, institutional, and fixed-installation environments without the maintenance demands of traditional cooling systems.

Amplifier Architecture & Connectivity

This 120W RMS single-channel amplifier features two analog audio inputs and integrated Ethernet connectivity for networked control and monitoring. The universal AC 100–240V, 50/60 Hz power supply ensures global deployment flexibility, while the auto power-off feature reduces energy consumption in standby conditions.

Audio Performance & Installation Flexibility

The amplifier delivers a 20 Hz to 20 kHz frequency response with 0.5% THD and a signal-to-noise ratio exceeding 100dB, ensuring clean audio reproduction across the full spectrum. Dual impedance support—4-ohm and 8-ohm loads—combined with 70V and 100V installation capability via RJ45 connectors makes this unit adaptable to varied speaker configurations and distributed audio systems.
