OPERATING PRINCIPLES
The operating concept behind the SCM410 Automatic Mixer is Shure's patented* IntelliMix circuitry. Intellimix delivers seam- less 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 acti- vated for a single sound source. One talker activates only one channel, even if multiple microphones ªhearº that talker.
•Last Mic
that background ambience is always present.
