The SCM410 is a 4-channel automatic microphone mixer designed for professional installed sound applications where multiple live microphones must be managed seamlessly without manual intervention. It is built around Shure's IntelliMix® circuitry, which automatically activates only the microphones being spoken into while attenuating inactive channels. This gated mixing approach helps maintain consistent system gain, significantly reduces ambient noise, and minimizes the risk of feedback in environments with multiple open microphones.
Unlike manual mixers that require an operator to adjust levels continuously, the SCM410 dynamically responds to speech activity in real time. It applies automatic mixing logic, including noise-based gating and last-mic-lock-on functionality, to ensure natural-sounding audio even in challenging acoustic environments. The unit also supports cascading with additional automatic mixers, allowing expansion for larger conferencing systems or multi-room installations.
The SCM410 is commonly used in boardrooms, council chambers, courtrooms, and other speech-intensive environments where clarity and reliability are critical. Its half-rack form factor allows flexible rack installation, either as a single unit or paired with other compatible Shure half-rack devices. With balanced microphone inputs, line-level outputs, and configurable control settings, it integrates easily into both simple and complex AV system designs.
Overall, the SCM410 is intended for applications that require hands-free microphone management, stable gain structure, and intelligible speech reproduction in multi-microphone environments.
