This eight-channel automatic mixer features the Shure patented IntelliMix®, which activates only microphones being addressed, minimizing poor audio caused by multiple open microphones.
The SCM810 is designed specifically for installed sound applications.
Features include adjustable EQ per channel, 48 V phantom power, active balanced microphone - or line-level inputs, line-level outputs, highly RF resistant chassis and circuitry, complete logic control of microphone activation, linking capacity for up to 400 microphones, with an internal power supply. 120/230 Vac power.
