- Description
Details
The SCM820 uses IntelliMix technology to dramatically improve audio quality when many channels of microphones need to operate simultaneously. Multiple I/O configurations and networking options ensure analog and digital connectivity between devices. It is designed for use in speech applications, including sound reinforcement, broadcasting and audio recording. The Shure SCM820-DB25 provides networking capabilities, comprehensive software control, AMX and Crestron compatibility, and analog / digital connectivity between devices. It offers IntelliMix® technology and digital feedback reduction. It also features 8 active-balanced microphone or line-level inputs and 8 dedicated, impedance-balanced direct outputs.

Features
IntelliMix Technology:
- Delivers seamless automatic mixing and reduced background noise through dynamic channel gating and attenuation
- NAT (Noise Adaptive Threshold) continuously adjusts the activation threshold for opening a channel
- Number of Open Microphones Attenuation (NOMA) determines the amount of gain attenuation for a mix output when the number of active microphones changes
- Last Mic Lock-On (LMLO) keeps the most recently activated microphone open until another microphone is activated
- MaxBus ensures that only one channel is opened per sound source, reducing comb filtering for clear and intelligible speech
- IntelliMix Modes offer five different mixer mode presets of reliable automixing styles (Classic, Smooth, Extreme, Custom, or Manual) to quickly tailor the mix for a particular application
Enhanced I/O Support for Greater application Flexibility and Digital Connectivity:
- DB25 connectors with 8 inputs
- Per-channel direct outputs allow the SCM820 to be used as an insert processor
- Mix A and B outputs with selectable mic or line level connect to a sound reinforcement system, mixing console, or recording device
- Dual mixer operation enables routing of independent automixes to the mix A and B outputs, allowing two entirely different mixes to result from the same set of inputs
- Aux inputs on both the front and back panel easily connect to media players
- 1/4" (6.35 mm) stereo headphone output for channel solo and mix monitoring
Comprehensive Control:
- Channel control knobs allow quick adjustment of gain, limiter, and EQ settings, and solo/mute functions on input channels
- Output mix controls and meters enable front-panel master gain and limiter control as well as signal monitoring
- LED meter rings display input audio or IntelliMix gain levels for each channel
- Browser-based control software delivers comprehensive software control, monitoring, routing, and configuration of all signals and settings and adds a parametric 8-band EQ
