JBL Professional CSM 28 8-Input, 2-Output Commercial Audio Mixer, 1U Full-Rack

Built for commercial sound applications, the JBL CSM 28 is a compact audio mixer that makes it easy to manage multiple audio sources in places like restaurants, schools, fitness centers, and retail spaces. It has 8 inputs and 2 outputs, so you can connect microphones, background music, and other audio sources while controlling sound levels independently. The fanless 1U rack-mount design saves space and runs quietly, making it a great fit for professional setups. Independent bass and treble controls let you fine-tune the audio, while priority muting ensures important announcements come through clearly. It’s compatible with JBL CSR-V wall controllers via a standard Ethernet cable, giving you remote volume control. The universal power supply works with 100–240V AC, so it’s ready for use in different locations without the need for adapters. With durable Euro-block connectors and unbalanced RCA inputs, it’s designed for easy installation and reliable performance in commercial environments.
