Equip your facility with reliable, easy-to-manage audio distribution using the JBL Professional CSM 28 audio mixer.

The CSM 28’s 8-input / 2-output architecture and configurable routing let you combine microphones, line-level sources and consumer devices while keeping program audio and paging channels separated.

Built-in features such as priority muting, VOX ducking and phantom power simplify mic management for live paging and security applications, while the GreenEdge energy-efficient design and universal power input (100–240 VAC) make installations straightforward worldwide. For integrators and facility managers who need dependable audio for paging, security and monitoring systems, the CSM 28 provides a compact, feature-rich solution.
