About Shure SCM410

The Shure SCM410 is a four-channel automatic microphone mixer designed for use in sound reinforcement, audio recording and broadcast applications. The SCM410 dramatically improves audio quality in any application where multiple microphones are required. Any low-impedance dynamic or condenser microphone (including wireless) can be used with the SCM410. Multiple SCM410 mixers can be linked to other SCM410 mixers, as well as to Shure Models FP410, SCM810, SCM800 and AMS8100 mixers.

Each input channel has a two-band equalizer and three logic terminals. The equalizer reduces unwanted low-frequency audio pickup and makes different microphone types - lavaliers, boundary and handheld-sound similar. The logic terminals can be used to control external devices. The SCM410 operates on 100-120 V AC power. The mixer is supplied with a power cord, rack-mounting hardware and a link cable.

Shure SCM410 Features

  • Fast, noise-free microphone selection, which automatically adjusts to changes in background noise
  • Automatic gain adjustment as additional microphones are activated-NOMA (Number of Open Microphones Attenuated)
  • Last Mic Lock-On circuit maintains ambient sound
  • Fits in half a rack space
  • Adjustable EQ for each channel
  • Active balanced microphone-level XLR inputs and an active balanced Mic/Line level XLR output
  • Unbalanced auxiliary-level phono output
  • Bi-color channel activation and clipping LEDs
  • Peak-responding output limiter with LED indicator
  • Peak-responding output level meter
