The Shure SCM410 is a sophisticated four-channel automatic microphone mixer engineered to deliver clear, intelligible audio in multi-participant speaking environments by intelligently managing multiple open microphones. Its primary function is to reduce background noise, comb filtering, and the potential for acoustic feedback by automatically activating only the microphones being used by active talkers while attenuating unused channels. The mixer employs Shure's proprietary IntelliMix® automatic mixing algorithms, which utilize gain-sharing and adaptive threshold technology to provide natural-sounding mixing without the abrupt gating or pumping artifacts associated with simpler automixers. This results in a cleaner sound reinforcement and recording experience in settings such as conference rooms, boardrooms, houses of worship, and courtrooms.

Each of the four channels is equipped with a balanced XLR microphone input, individual gain control, and phantom power capability for condenser microphones. The SCM410 offers a high degree of control and flexibility, with adjustable parameters for threshold, attack and release times, and a configurable "Maximum Open Mics" (MOM) setting to limit the number of simultaneously active channels, optimizing gain before feedback. It provides both automatic and manual mixing modes, allowing the system to be tailored for different types of meetings or events. Outputs typically include a main mixed output on XLR and an auxiliary output for recording or sending to a teleconferencing system, ensuring versatile integration into existing audio systems.

Designed for professional fixed installations, the SCM410 features a robust metal chassis suitable for rack mounting with optional ears. Its set-and-forget operation makes it ideal for environments where users have varying levels of technical expertise, as it automates the critical task of microphone management. By ensuring that only relevant audio sources are amplified, it allows the overall sound system to operate at higher levels with greater clarity and stability. The Shure SCM410 represents a reliable and intelligent solution for improving speech intelligibility and system performance in any application where multiple microphones are used simultaneously.
