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.

Eight balanced mic-line input channels (Phoenix block connectors)

One unbalanced 1/4" aux level input

Eight unbalanced 1/4" direct line level outputs

One balanced master line level output (Phoenix block connector)

Selectable 46V phantom power per channel

Level selectable peak output limiter

Full rack width (single rack height)
