Shure SCM810 Eight-Channel Automatic Microphone Mixer (SCM810)

The Shure SCM810 is a professional eight-channel automatic microphone mixer designed to deliver clear, intelligible audio in environments with multiple microphones. Built with Shure’s IntelliMix technology, the SCM810 intelligently activates only the microphones in use, significantly reducing background noise, feedback, and comb filtering caused by multiple open microphones. Engineered for conferencing, broadcast, and sound reinforcement applications, this mixer ensures seamless audio performance through automatic gain control (NOMA), last-mic lock-on, and fast, noise-free switching. Its rackmount design, robust RF-resistant construction, and flexible connectivity make it ideal for both fixed installations and scalable systems. With the ability to link multiple units for up to 400 microphone inputs, the SCM810 provides a reliable, enterprise-grade solution for complex audio environments.
