JBL PROFESSIONAL CSA-140Z - 40W Commercial Power Amplifier
The JBL Professional CSA-140Z is a high-performance power amplifier designed specifically for commercial and industrial sound applications. This unit combines robust power with highly efficient operation and a compact design, making it the ideal solution for fixed installations in restaurants, retail stores, offices, and other public spaces. With a 40-watt output channel, the CSA-140Z can drive both low-impedance (4 and 8 ohms) and constant-voltage (70V and 100V) speaker systems without the need for an external transformer, offering exceptional versatility.
At the heart of the CSA-140Z is Crown's innovative DriveCore™ technology, which integrates the amplifier's drive stage into the power output stage on a single chip. This revolutionary technology dramatically reduces the number of components required, resulting in greater reliability, lower power consumption, and pristine sound performance. Its fanless design ensures completely silent operation, a crucial factor for environments where ambient noise must be minimal. Furthermore, its compact 1U, half-rack-width chassis makes it easy to install anywhere, even in confined spaces, and includes a rack-mount kit for added convenience.
