The Shure SCM410E is a four-channel automatic microphone mixer for use in sound reinforcement, audio recording, and broadcast applications. The SCM410 dramatically improves audio quality in any application where multiple microphones are required.
- Increases the clarity and intelligibility of speech
- Dramatically reduces feedback, reverberation, and comb filtering
- Automates several rigorous operator functions
- Minimizes set up time - plug and play
- Frees up channels on the mixing console
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
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.
Any low-impedance dynamic or condenser microphone (including wireless) can be used with the SCM410. Multiple SCM410 mixers can be linked to other SCM410 mixers, as well as to Shure Models SCM810, and SCM800.
Each input channel has a two-band equalizer and three logic terminals. The equalizer reduces unwanted low-frequency audio pickup and makes different microphone types-lavaliers, boundary and handheld sound similar. The logic terminals can be used to control external devices. Each mixer is supplied with a power cord, rack-mounting hardware, and a link cable.
The operating concept behind the SCM410 Automatic Mixer is Shure's patented* IntelliMix circuitry. Intellimix delivers seamless automatic mixing by combining three separate functions:
- Noise Adaptive Threshold: Distinguishes between constant background noise (such as air conditioning) and changing sound (such as speech) for each input channel. It continuously adjusts the activation threshold so that only speech levels louder than the background noise activate a channel.
- MaxBus: Controls the number of channels that may be activated for a single sound source. One talker activates only one channel, even if multiple microphones “hear” that talker.
- Last Mic Lock-On: Keeps the most recently activated microphone open until another microphone is activated. Without Last Mic Lock-On, a long pause in conversation would cause all microphones to turn off, which would sound as if the audio signal had been lost. Last Mic Lock-On ensures that background ambience is always present.
