JBL Professional CSMA 180 4-Input, 1-Output Commercial Mixer-Amplifier 80Wx1 at 70V

Provide dependable background music and instant paging for small-to-medium commercial environments with the JBL Professional CSMA 180 mixer-amplifier. This compact pro amplifier combines practical controls and flexible connectivity so you can manage music, announcements and security monitoring from a single 1U rack unit. With 80W RMS power and native 70V/100V distributed-audio support, the CSMA 180 delivers even coverage for retail, hospitality, education and security installations without separate transformers. Four inputs — including a priority mic channel — let you blend music with live paging or emergency messages, while priority muting and configurable output routing ensure critical announcements always get through. The fanless design keeps noise to a minimum in sensitive monitoring or surveillance rooms, and illuminated, signal-sensing front knobs make operation simple even when installed in a dark cabinet. RJ-45 remote volume capability adds convenient centralized control for multi-zone setups. Ideal for integrators and facility managers specifying systems for retail, security, or AV projects — add the CSMA 180 to your next distributed audio, paging or surveillance deployment and contact us to request a quote or demo.
