JBL Professional CSA 1120Z - Single-Channel 70V/100V Power Amplifier

The JBL CSA 1120Z amplifier is a professional device from the Commercial Series, delivering powerful and clean sound in commercial installations. Thanks to advanced technology and a compact design, it provides a reliable solution for demanding audio reinforcement systems.

Product Features

The device stands out with built-in support for 70V and 100V lines, an output power of 120W per channel, and proprietary Crown DriveCore technology. It features a fanless 1U design, a universal voltage power supply, and Energy Star certification. Illuminated rings around the knobs facilitate operation, while the RJ45 connector enables compatibility with JBL CSR-V wall controllers.

Professional Capabilities for Your Creativity

The JBL CSA 1120Z power amplifier leverages innovations from HARMAN brands, ensuring sound quality that exceeds standard expectations. At the heart of the device is the Crown DriveCore circuit, which replaces nearly 500 components with a single integrated circuit, drastically reducing the number of parts and increasing reliability. This integration allows for excellent signal quality with lower energy consumption. Thanks to the sleep mode disable function and the HARMAN GreenEdge eco-initiative, the equipment quickly delivers operational savings.

The enclosure, with a height of just 1U, does not require fans, eliminating noise and facilitating rack mounting without thermal constraints. The universal power supply accepts AC voltages from 100 to 240V at 50/60 Hz, enabling operation in various regions worldwide. Illuminated rings visually confirm activity and facilitate adjustment in poorly lit technical rooms. The RJ45 connector for control via Ethernet cable with JBL CSR-V regulators allows for convenient volume changes from the wall at the listening zone.

The JBL CSA 1120Z is ready to work right out of the box with support for transformer-based 70V and 100V installations, commonly used in distributed speaker systems. Input sensitivity of 1.4Vrms for 8 ohms and input impedance of 20k or 50k ohms ensure compatibility with a wide range of mixers and sources. 27VDC phantom power supports condenser microphones in simple presentation applications.
