Part of Shure's Automatic series of mixers, the Shure SCM810 8-Channel Microphone Mixer provides a feature set and sonic quality suitable for any sound reinforcement scenario. The SCM810 features 8 Mic/Line level inputs via removable Block Connectors. All inputs are balanced and provide phantom power for condenser microphones. There are 8 direct outputs (1 per input channel) for direct routing of incoming signal to recorders monitors etc. Low-cut filter and High-shelving EQ switches are provided on all input channels. In addition to the mixers sonic quality, the SCM810's automatic features offer complete, hands free operation between multiple microphones.
It has 7 position-programmable switches to provide further modifications to internal features; the limiter threshold, off-attenuation level, and hold time can be adjusted, and the mixer can be switched between manual and automatic modes.
The SCM810's Noise Adaptive threshold distinguishes between constant background noise and audio signal fluctuating in pitch, level and consistency (speech). The threshold continuously adjust so that speech levels louder than background noise activate that channel. The Max Bus feature controls the number of channels that activate when triggered by a signal. The Max Bus feature can be set so that one talker activates one channel, even if multiple microphones "hear" that talker. This results in a constant switching between talkers on a panel or discussion. Last Mic Lock-On feature keeps the most recently used mic active so that ambient room signal remains when mics are not in use. The result is a natural uninterrupted signal flow.

Comments about Shure SCM810 8-Channel Microphone Mixer:
We've used and trusted this equipment for years. Out of a dozen or so that we have had in uses on a daily basis for years, only two have failed. We are so pleased with the performance and reliability that we chose to replace the failed units with exactly the same models. They have lastest well past their warranty periods.
