JBL CSA 240Z - 40W 2-Channel 70V/100V Power Amplifier with Master Volume Knob and RJ45 Connectors in Black Finish

The JBL Professional CSA 240Z is a compact and efficient 40W 2-channel power amplifier designed for installed sound applications where space and energy efficiency are paramount. With Crown's DriveCore technology, this amplifier provides powerful sound amplification with remarkable reliability and low power consumption, making it ideal for commercial environments such as retail stores, offices, conference rooms, and more. The CSA 240Z offers high-quality sound while reducing environmental impact and operational costs, making it a great solution for modern audio systems that require both performance and sustainability.

This amplifier is versatile, supporting both 70V and 100V output configurations out of the box. It is perfectly suited for large-scale, distributed audio systems where long cable runs are needed, allowing clear and consistent sound across multiple speakers or zones. The CSA 240Z includes two RJ45 connectors, providing compatibility with JBL's CSR-V wall controllers (sold separately) for remote volume control via CAT5 cable, making it ideal for multi-zone installations. This feature ensures that users can easily manage audio levels from a central location, enhancing both convenience and efficiency in commercial setups.

The CSA 240Z features a sleek, industrial 1U design, making it compact enough for space-constrained installations, yet powerful enough to handle a variety of professional sound systems. Its fanless design ensures silent operation, which is particularly important for noise-sensitive environments like conference rooms and offices. Additionally, the amplifier is equipped with illuminated volume knobs that provide clear visual feedback, making adjustments easy even in low-light conditions. The universal power supply allows the amplifier to accept AC voltages from 100 to 240V at 50/60 Hz, offering global compatibility for international installations.

In terms of performance, the CSA 240Z delivers a frequency response from 20 Hz to 20 kHz (+/-0.5 dB), ensuring that the full range of audio, from deep bass to high treble, is accurately reproduced. The unit boasts total harmonic distortion (THD) of less than 0.5% at full rated power, ensuring that the sound remains clean and distortion-free even at higher output levels. The signal-to-noise ratio of greater than 100 dB ensures that the amplifier performs with exceptional clarity, without unwanted background noise or hum. The amplifier also includes independent bass and treble tone controls, providing users with the flexibility to adjust the sound to match the specific acoustics of their environment.

The CSA 240Z is designed with energy efficiency in mind, featuring a sleep mode disable function that allows it to enter standby mode when no signal is detected, helping to conserve power during periods of inactivity. The amplifier also meets HARMAN's GreenEdge environmental initiative, ensuring minimal environmental impact through sustainable manufacturing practices. Certified with Energy Star, the CSA 240Z operates efficiently, providing long-term cost savings while delivering outstanding sound quality.

Whether used for background music, paging systems, or other commercial audio applications, the JBL CSA 240Z offers excellent performance, energy efficiency, and user-friendly features that make it an ideal choice for professional sound systems.
