JBL CSA 2300Z - 300W 2-Channel 70V/100V Power Amplifier with Master Volume Knob and RJ45 Connectors in Black Finish

The JBL Professional CSA 2300Z is a high-performance 300W dual-channel power amplifier designed for installed sound applications that demand both power and efficiency. Utilizing Crown's DriveCore technology, the CSA 2300Z delivers powerful, reliable amplification in a compact form factor, making it ideal for commercial spaces, educational institutions, retail environments, and other large venues. This amplifier provides exceptional sound quality while maintaining high performance and reducing the overall component count, making it both a reliable and cost-effective solution for a wide range of professional audio installations.

The CSA 2300Z features a sleek, industrial 2 RU design that allows it to fit seamlessly into standard equipment racks, saving valuable space in environments where space constraints are a concern. The amplifier provides 300W of output per channel, with built-in 70V and 100V support, making it versatile for use in both low-impedance and high-voltage distributed audio systems. Its high power output ensures clear, consistent sound across large areas or multiple zones, even with long cable runs or numerous speakers.

Designed for flexibility and ease of use, the CSA 2300Z includes illuminated master volume knobs for both output channels, making it simple to adjust volume levels, even in low-light conditions. The amplifier is equipped with both balanced and unbalanced input options, including Euro-block style connectors and RCA mono sum inputs, providing compatibility with a wide range of audio sources. Additionally, the CSA 2300Z offers tone controls for both bass (+/-12 dB at 100 Hz) and treble (+/-12 dB at 10 kHz), allowing for fine-tuning of the sound to suit various room acoustics and system requirements.

The amplifier supports remote volume control through JBL's CSR-V wall control module via RJ45 connectors and standard CAT5 cable, making it an excellent choice for installations that require centralized volume management across multiple zones or locations. This feature provides convenience and ease of operation in environments with complex audio setups. Furthermore, the CSA 2300Z supports RS232 control, offering the ability to control volume, mute, and sleep mode via external systems, enhancing its integration with third-party automation systems.

For energy efficiency, the CSA 2300Z includes a sleep mode disable function that helps conserve energy when no signal is detected. The amplifier also meets HARMAN's GreenEdge environmental standards, ensuring minimal environmental impact. The unit is Energy Star certified, offering long-term operational savings without sacrificing performance. With its universal power supply that supports AC voltages from 100V to 240V at 50/60 Hz, the CSA 2300Z is suitable for global installations, ensuring compatibility with electrical systems worldwide.

The CSA 2300Z delivers outstanding performance with a frequency response of 80 Hz - 20 kHz (+/-1.0 dB), ensuring clear and precise audio reproduction. The total harmonic distortion (THD) is kept below 0.5% at full rated power (20 Hz - 20 kHz), ensuring clean, distortion-free sound even at higher output levels. With a signal-to-noise ratio of greater than 97 dB, the amplifier ensures quiet, background noise-free operation, making it perfect for environments where audio clarity is essential.

In addition to its performance, the CSA 2300Z provides robust protection features, including over-temperature and low-voltage protection, ensuring reliable operation even in demanding conditions. With its combination of high output power, versatile connectivity options, and energy-efficient design, the CSA 2300Z is an ideal solution for large-scale audio installations that require professional-grade performance.
