Alerts and Thresholds
MultiTuner monitors signal parameters continuously and triggers alerts when measured values fall outside configured thresholds. Each channel has its own independent threshold settings, allowing you to account for differences in expected signal levels across your monitored stations.
Opening Alert Settings
Click the alert icon on a channel tile to open the threshold configuration for that slot.
Configurable Thresholds
| Parameter | Description |
|---|---|
| RF Level — Low | Alert when received signal strength drops below this value |
| RF Level — High | Alert when signal strength exceeds this value (e.g. overload or interferer) |
| SNR — Low | Alert when the signal-to-noise ratio falls below the threshold |
| Interference — High | Alert when detected interference exceeds this percentage |
| Pilot — Loss | Alert when the FM stereo pilot signal is absent |
| Audio — Silence | Alert when audio level falls below the silence detection threshold |
Alert Behavior
When a threshold is breached, the affected channel tile is highlighted in the main monitoring view. Alerts are visible immediately without any page refresh.
Setting thresholds
Before configuring thresholds, let MultiTuner run for 24–48 hours to collect baseline measurements from your broadcast environment. Use those baselines to set thresholds that reflect realistic operating ranges for each station, rather than using generic values.
Integration with MultiProbe
When MultiTuner is connected to a Stream Labs MultiProbe Central Server, all channel alarms are forwarded to the central alarm manager. This enables:
- A consolidated alarm view across multiple devices and sites
- Alarm notifications via email, SMS, or third-party integrations
- Full alarm event history with timestamps for retrospective analysis
- Scheduled compliance reports
For configuration details, refer to the MultiProbe documentation.
