JBL CSA 140Z – Single-Channel 70V/100V Power Amplifier

The JBL CSA 140Z is a professional power amplifier designed for permanent public address installations. With support for 70V and 100V line voltages, it allows for simple expansion of PA systems in commercial and institutional buildings.

Product Features

The amplifier features a single-channel architecture and operates in 70V/100V line mode. It utilizes JBL's proprietary DriveCore technology, which replaces multiple components with a single integrated circuit, reducing the number of parts and increasing reliability. The device delivers 40 watts of power and includes RJ-45 connectors for compatibility with wall-mounted volume controls.

Compact Solution for Commercial Installations

The JBL CSA 140Z combines configuration simplicity with energy efficiency, resulting in lower power consumption compared to traditional amplifiers. Thanks to DriveCore technology, the internal structure has been simplified – instead of many discrete components, a single small chip is used, which reduces failure rates and simplifies servicing. The enclosure dimensions are a mere 11.9 x 8.6 x 1.7 inches, allowing for surface mounting or rack installation using the included kit. The amplifier supports input voltages ranging from 100 to 240 V AC, making it suitable for various locations. RJ-45 connectors enable direct connection to in-wall volume controls, making the system intuitive for daily operation. The JBL CSA 140Z is equipment for system integrators and facility owners who need stable, clean sound without unnecessary complications.
