The JBL's CSM14 four inputs/one output commercial series analog mixer is backed by the combined technological prowess of multiple Harman brands and can be easily configured for a variety of applications including background music, security, and paging in schools, hospitals, restaurants, and fitness facilities. The mixer has Euroblock mic/line input and output connectors as well as unbalanced RCA inputs for I/O. The dedicated volume, bass, and treble controls are lighted on the chassis, making them simpler to see and use. A +27V phantom power switch and a 70 Hz HPF switch are located on the back of the mixer.
RJ45 connectors are included for use with the company's CSR-V in-wall volume controls (available separately), as well as a universal power supply that accommodates AC voltages from 100 to 240 VAC, 50/60 Hz. It was designed utilising Harman's GreenEdge clean standards to provide a number of energy-saving benefits, including a lighter weight, space-saving design that meets RoHS requirements.
