JBL CSA 140Z - 40W 1-Channel 70V/100V Power Amplifier with Master Volume Knob and RJ45 Connectors in Black Finish

The JBL Professional CSA 140Z is a compact yet powerful 40W 1-channel power amplifier designed to meet the needs of installed audio applications. Whether used in retail environments, restaurants, educational institutions, or other commercial spaces, this amplifier provides efficient and reliable sound amplification in a sleek, space-saving 1U design. With Crown's DriveCore technology, the CSA 140Z delivers high-quality sound with exceptional efficiency, reducing both power consumption and heat generation. This makes it an excellent solution for continuous operation in a variety of commercial installations.

Equipped with both 70V and 100V outputs, the CSA 140Z is built to handle distributed audio systems effortlessly, ensuring clear and consistent sound across long distances or large installations. The unit includes an RJ45 connector, allowing for remote volume control using the JBL CSR-V wall controller (sold separately), providing easy management of audio levels across multiple zones. This feature is especially useful for systems requiring centralized control or in environments where volume adjustments need to be made remotely from various locations.

The CSA 140Z features intuitive, illuminated knobs for master volume and tone adjustments, making them easy to use and visible, even in low-light conditions. It also includes a universal power supply, compatible with AC voltages ranging from 100 to 240V at 50/60 Hz, allowing for global use in various installations. Additionally, the amplifier's fanless design ensures quiet operation, making it ideal for noise-sensitive environments like conference rooms or offices. For energy efficiency, the amplifier also includes a sleep mode disable function, which can be activated to automatically power down the unit after a period of inactivity, helping conserve energy when not in use.

With high-quality audio performance in mind, the CSA 140Z offers a frequency response of 20 Hz to 20 kHz (+/-0.5 dB), ensuring rich, full-range sound reproduction. The total harmonic distortion (THD) is kept below 0.5% at full rated power, delivering clean and distortion-free sound even at high volumes. The unit's signal-to-noise ratio is over 100 dB, providing excellent clarity and low background noise. It also features independent bass and treble tone controls, offering additional flexibility in shaping the sound to match the acoustic properties of the installation space.

In addition to its exceptional performance, the CSA 140Z is built with sustainability in mind. The amplifier is Energy Star certified and meets HARMAN's GreenEdge environmental initiative, ensuring it operates with minimal environmental impact. It is designed to meet lead-free ROHS standards and incorporates an energy-efficient, recycled metal construction. Whether used in a single-zone or multi-zone configuration, the CSA 140Z provides the performance, reliability, and flexibility needed for demanding commercial applications.
