JBL CSMA 180 - 80W Commercial Mixer/Amplifier with 4 Inputs and 1 Output in Black Finish

The JBL Professional CSMA 180 is a compact and efficient 80W commercial mixer/amplifier designed to meet the demands of commercial and industrial environments. Perfect for use in spaces such as restaurants, educational institutions, fitness centers, and retail stores, the CSMA 180 provides flexible audio mixing and amplification in a space-saving 1U design. With four mixer-channel inputs and one output channel, this unit delivers 80W of peak power, with 10W of continuous power per channel, making it suitable for applications requiring clear audio in relatively smaller spaces.

Featuring a sleek industrial look, the CSMA 180 is designed for ease of operation. The front panel includes illuminated volume controls for each input channel, as well as a master volume knob, bass and treble controls, and a power switch, all of which are clearly visible, even in darkened environments. This feature ensures that adjustments can be made quickly and effectively in any setting. The amplifier can drive both 8-ohm and 4-ohm loads and supports 70V and 100V distributed audio systems without the need for a separate transformer, offering great flexibility for a variety of commercial audio setups.

The CSMA 180 is equipped with multiple input options, including Euro-block type mic/line connectors and unbalanced RCA inputs, making it compatible with a wide range of audio devices. On the back panel, users will find additional features such as Hi-Z and phantom power switches for easy integration with microphones and other equipment. Additionally, the CSMA 180 offers an auxiliary output that allows users to connect to an additional amplifier, though the master volume and tone controls will not affect this output. For more advanced control, the unit is equipped with an RJ45 connector for use with the JBL CSR-V in-wall volume control module (sold separately), enabling remote volume control through a standard Ethernet cable.

For added functionality, the CSMA 180 includes features like voice-activated ducking, which automatically reduces the music volume when announcements are made, and priority muting for channel one's input. These features are essential for environments where paging and background music need to coexist. The amplifier also features a sleep mode that powers down the unit after 30 minutes of inactivity, helping conserve energy. The CSMA 180 uses Crown's DriveCore technology to deliver excellent audio performance with high efficiency, making it a reliable and energy-saving solution for professional audio needs. The unit is also Energy Star certified and meets lead-free ROHS standards, using recycled metals and an energy-saving powder-coat process for added environmental benefit.
