If your Sennheiser device is losing its Dante clock, the issue likely stems from network synchronization or configuration problems. Below is a breakdown of what to check and how to troubleshoot:
Check Clock Master Settings
- In Dante Controller, verify which device is set as the Preferred Master. If your device is not the master, ensure its syncing to a stable master.
- Avoid having multiple devices set as Preferred Master unless redundancy is intended.
Network Stability
- Use a dedicated Dante network or VLAN to isolate Dante traffic from general data traffic.
- Ensure all Dante devices are connected to a Gigabit switch with low latency and no packet loss.
- Disable Energy Efficient Ethernet (EEE) on switches, as it can disrupt Dante clocking.
Firmware Updates
- Make sure all Dante-enabled devices are running the latest firmware. Updates often resolve clocking and sync issues.
Multicast Configuration
- Dante uses multicast for clock distribution. Ensure your network supports multicast and that IGMP Snooping is properly configured.
- If multicast is blocked or misconfigured, clock sync will fail intermittently.
Device Prioritization
- If using multiple Dante devices, prioritize those with the most stable clocks (e.g., mixing consoles or dedicated clock sources) as the master.
Cabling and Physical Setup
- Use shielded Cat5e or Cat6 cables and check for damaged connectors or cables.
- Avoid daisy-chaining devices; use a star topology with a central switch.
