JBL Professional CSA 180Z - Single-Channel 70V/100V Power Amplifier

The JBL Professional CSA 180Z is a compact and highly reliable device from the Commercial Series, delivering 80 watts of power on a single channel. Designed for professional sound reinforcement installations, it combines HARMAN brand technologies with Crown DriveCore innovations, offering powerful and clean sound.

Product Features

The amplifier features built-in support for 70V and 100V lines, a fanless 1U design that saves space, and Crown DriveCore technology that replaces up to 500 components with a single integrated circuit. It has a universal power supply accepting voltages of 100–240V AC, a sleep mode disable function, and Energy Star certification. Illuminated rings around the knobs facilitate operation, and the RJ45 connector allows for compatibility with JBL CSR-V wall-mounted volume controllers.

Professional Capabilities for Commercial Audio Systems

The JBL CSA 180Z is an excellent solution for facilities requiring durable and energy-efficient sound reinforcement. Thanks to the switching power supply with universal input voltage, the device can operate in various network conditions without the need for transformers. Crown DriveCore technology significantly reduces the number of electronic components, which translates to high reliability and a long amplifier lifespan. The fanless construction eliminates noise generated by active cooling, making it ideal for quiet spaces such as offices, receptions, or conference rooms. The low-profile 1U chassis allows for mounting in standard rack cabinets, and the included mounting kit simplifies installation. The amplifier supports JBL CSR-V volume controllers connected via standard Ethernet cable, simplifying wiring and zone configuration. Thanks to the HARMAN GreenEdge initiative, the device contributes to energy savings, and the Energy Star certification confirms its high efficiency. This amplifier is suitable for both new installations and the modernization of existing 70V and 100V systems, ensuring consistent quality for music playback and voice announcements.
