Eight-channel automatic mixer features the Shure patented IntelliMix®, which activates only microphones being addressed, minimizing poor audio caused by multiple open microphones. 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. 120/230Vac power.
Reliable, quick-acting, noise-free microphone selection which automatically adjusts to changes in background room noise
User-configurable parameters for automatic operation
Automatic gain adjustment as additional microphones are activated (NOMA: Number of Open Microphones Attenuator)
Last Mic Lock-On circuit maintains ambient sound
Adjustable EQ per channel: low-frequency rolloff and highfrequency shelving
Eight unbalanced 1/4 inch direct line level outputs
One balanced master line/mic level output (Phoenix block connector)
Level selectable peak output limiter
Full rack width (single rack height)
48 V phantom power selectable for each input
Active balanced microphone- and line-level inputs and linelevel output
Highly RF-resistant chassis and circuitry
Bi-color LED indication of channel activation and clipping
Linking capability for systems up to 400 microphones
Non-automatic aux-level inputs with level control
Front-panel headphones output with level control
Peak-responding output limiter with selectable thresh olds and LED indicator
Internal modification permits 120 V operation (SCM810) or 230 V operation (SCM810E)
