Shure
MXA920
The MXA920 is a ceiling array microphone with steerable coverage zones configured through Shure Designer software.
Before connecting the MXA920 to Voice Tracking, log into the microphone's own web interface and enable Automatic Coverage. Without this setting, the MXA920 will not report zone-level audio activity.
Connection
- Enable Automatic Coverage in the MXA920's web interface.
- In Voice Tracking, select Shure MXA920 from the Microphone Type dropdown.
- Enter the MXA920's IP Address.
- Enter the Port.
- Adjust the Threshold Settings as needed.
- Click Start Microphone.
16 Zones will populate once the microphone is started. Assign cameras and presets to each zone from the zone map.
About Threshold Settings
Threshold settings control how Voice Tracking interprets audio data from the microphone to determine when to switch zones. Adjusting these settings can help optimize tracking performance for different room acoustics and noise levels. Some microphones (like the Televic Confero and Yamaha RM-CG) do not allow adjustment of all threshold settings, but the core principles apply across all supported microphones.
| Threshold | Purpose | Notes |
|---|---|---|
| Decibel Threshold | Sets the noise floor, audio below this level is ignored | Increase in noisy rooms (HVAC, projectors) |
| Verification Threshold | Consecutive 100ms readings to verify a voice | Default: 3 |
| Identification Threshold | Verifications required before action fires | Default: 3 |
| Silence Threshold | Seconds of silence before silence zone activates | Default: 7 seconds |
General Tips
Giving zones clear, descriptive names (matching your physical room areas) makes zone-to-camera assignment easier and helps you identify which zone is active at a glance on the zone map.
Refer to your microphone system's documentation for the default API port. For the Nureva HDL410, the port is displayed in Nureva Console under Local Integrations.
