The ShureSCM820-DAN-DB25 Digital IntelliMix Automatic Mixer is an 8-channel digital automatic mixer designed for use in speech applications, including sound reinforcement, broadcasting and audio recording. It uses Intellimix technology to dramatically improve audio quality in any application where multiple microphones are required and to select channels to open to the mix bus, while attenuating other channels. It comes with a DB25 connector with 8 inputs and features a Dante Digital Audio network interface card.
Digital audio is carried over standard Ethernet using shielded Cat5e (or higher) cables. Dante provides low latency, tight clock synchronization, and high Quality-of-Service (QoS) to provide reliable audio transport to a variety of Dante devices. Dante audio can coexist safely on the same network as IT and control data, or can be configured to use a dedicated network.
Note: Cat 5e cable is sold separately.
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
DB25 connector with 8 inputs
Per-channel direct outputs allows the mixer 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" (6.35mm) stereo headphone output for channel solo and mix monitoring
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
Dante digital networked audio enabled
Enables multi-channel audio networking over Ethernet
Control system compatible (AMX, Crestron)
