Shure SCM810E 8-Channel Automatic Mixer

8-channel automatic mixer improves audio quality in any application in which multiple microphones are required. Features include fast microphone selection, adjustable EQ, adjustable low-frequency roll off, and peak-responding output limiter.

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.

 

 

FEATURES

 

  • 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
