The Shure SCM410 4-Channel Automatic Microphone Mixer dramatically improves audio quality in any application in which multiple microphones are required. Features include fast microphone selection, adjustable EQ, and clipping LEDs, and peak-responding output limiter.
Automatic mixing is a tremendous problem-solving tool allowing sound system installers to eliminate common problems such as insufficient gain before feedback and muddy speech quality. Shure is the industry leader in automatic mixing with our unique IntelliMix® technology. IntelliMix automatically gates microphones on and off to optimize sound quality in conference facilities, houses of worship, governmental institutions, schools, etc. The Shure SCM410 Automatic Mixer puts all the seamless performance of the 8-channel SCM810 - the recognized standard in automatic mixing - into a half-rack space.
The SCM410 can be used as a turnkey mixing solution in a variety of speech applications:
- Fixed Audio Installations - houses of worship, schools, conference facilities, legislature, hotels
- Portable Applications - rentals, A/V carts, portable audio racks
- Interfaces with Crestron control systems
