Shure SCM410 – Four-Channel Automatic Microphone Mixer

Product Overview

The Shure SCM410 four-channel automatic microphone mixer is purpose-built for conference rooms, boardrooms, broadcast studios, and government spaces where consistent, hands-free audio pickup across multiple microphones is required. Powered by Shure's patented IntelliMix technology, the SCM410 automatically activates only the microphone detecting speech, keeping inactive channels attenuated and background noise suppressed without manual operator intervention. Its half-rack form factor integrates cleanly into standard AV rack enclosures, making it a reliable centerpiece for multi-mic installations up to four channels.

Product Description

The SCM410 accepts any low-impedance dynamic or condenser microphone—including wireless receiver outputs—across four independent input channels, each equipped with a two-band equalizer for room-specific tuning without requiring external DSP. IntelliMix's Noise Adaptive Threshold continuously distinguishes constant background noise from changing speech signals, reducing false triggers in acoustically challenging environments such as open offices or large government chambers. Three logic terminals per channel enable direct integration with AMX, Crestron, and other room control systems for status indication or automated switching. When a deployment exceeds four channels, multiple SCM410 units can be linked together via the included link cable, and the system also cascades with Shure's SCM810 and SCM800 mixers for larger installations. A peak-responding output limiter protects downstream signal chain equipment from clipping caused by sudden transients. The SCM410 ships with a power cord, rack-mounting hardware for single or dual half-rack mounting, and a link cable.

Key Features

• IntelliMix Automatic Mixing — Shure's patented algorithm activates only the microphone detecting speech, keeping background noise suppressed on inactive channels throughout a session.
• NOMA (Number of Open Microphones Attenuated) — Automatically reduces system gain as additional microphone channels open, maintaining consistent and predictable output levels across varying microphone counts.
• Per-Channel Two-Band EQ — Independent equalization on each input allows room-specific tuning to compensate for acoustic conditions without adding external processing.
• Three Logic Terminals per Channel — Facilitates integration with room control systems, occupancy sensors, indicator lights, or external switching logic for AV automation.
• Noise Adaptive Threshold — Continuously distinguishes ambient background noise from speech signals, significantly reducing nuisance activations in noisy environments.
• Cascade/Link Expansion — Multiple SCM410 units can be linked together and combined with Shure SCM810 or SCM800 mixers to scale installations beyond four input channels.
• Half-Rack Form Factor — Fits standard AV rack enclosures; rack-mounting hardware for both single and dual half-rack configurations is included.
• Peak-Responding Output Limiter — Protects connected DSPs, amplifiers, and recording equipment from clipping caused by sudden high-level transients.
• Broad Microphone Compatibility — Works with any low-impedance dynamic or condenser microphone, including outputs from wireless receiver systems, for flexible source integration.

Technical Specifications

Frequently Asked Questions

• Is the SCM410 compatible with wireless microphone receivers? Yes — the SCM410 accepts any low-impedance microphone input, including line-level outputs from wireless receiver systems, making it a straightforward addition to existing wireless AV setups.
• Can I expand beyond four channels? Yes — multiple SCM410 units link together via the included link cable, and the system cascades with Shure's SCM810 (8-channel) and SCM800 mixers for larger multi-mic conference or broadcast deployments.
• Does the SCM410 integrate with room control systems? Yes — three logic terminals per channel allow direct connection to AMX, Crestron, or similar control processors for automation, occupancy-based activation, or status indication.
• Does the SCM410 include rack-mounting hardware? Yes — hardware for both single and dual half-rack mounting is included, along with a power cord and link cable.
• What is the warranty on the SCM410? Shure provides a two-year limited warranty on professional products. Contact Creation Networks for purchasing and warranty support.
