Where can I use the SCM820?
The SCM820 improves the audio quality in all speech applications where multiple microphones are used. Typical use cases include educational institutions, offices, places of worship, hotels or broadcast studios. The SCM820 proves its strengths in panel discussions, town hall meetings, corporate events, press conferences or A/V conferences.
What is IntelliMix?
IntelliMix is an optimised algorithm featuring a unique collection of technologies. It activates the best microphone for a particular talker, while attenuating microphones that are not being addressed. By minimising the number of open microphones, it increases intelligibility and gain-before-feedback and reduces background noise.
- Noise Adaptive Threshold (NAT): Continuously adjusts the activation threshold for opening a channel. If for example an additional noise source like an Air Condition suddenly increases the ambient noise floor, the NAT adjusts the threshold accordingly so that the Mic channel will not be opened unintentionally.
- Number of Open Microphones Attenuation (NOMA): Determines the amount of gain attenuation for a mix output when the number of active microphone changes. So if more channels become active and several talkers are speaking simultaneously, the output level will not sum and increase the risk of feedback.
- Last Mic Lock on (LMLO): Keeps the most recently activated microphone open until another microphone is activated. If a talker pauses, the microphone channel remains open and no disruption will caused by activating this channel.
- MaxBus: Ensures that only one channel is opened per sound source, reducing comb filtering for clear and intelligible speech.
IntelliMix provides reliable tailored mixer modes, which are style presets to quickly adjust the mix for various applications or acoustical environments:
What further features does the SCM820 offer?
Variations of the SCM820 include output options of logic-enabled block connector or DB25 connector versions. There's also an SCM820 Dante card available, which can be used to upgrade standard Ethernet versions. A dual mixer operation allows for two separate 8-channel automixes from one set of inputs. Via easy daisy chaining, it's possible to auto link up to four units, while the usage of an external network switch allows to link up to 12 units leading to an automix of max. 96 channels. Digital Feedback Reduction (DFR) adds two channels of adaptive EQ filtering to find and attenuate frequencies with too much gain, preventing the onset of feedback and leading to an even higher sound quality.
