Shure SCM410 4-Channel Automatic Mixer

The Shure SCM410 4-Channel Mixer features "Automatic Mixing", 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 its unique IntelliMix technology. IntelliMix automatically gates microphones on and off to optimize sound quality in conference facilities, houses of worship, governmental institutions, schools, etc.
