Updated at February 13th, 2025

Information


Sennheiser and Q-SYS have identified rare cases where Third Party communication via TCP and UDP stops working after random durations (days/weeks) in some TCC 2 installations. Commands like beam angle position data and mic level stop updating until the TCC 2 is rebooted.

The root cause is under investigation, and updates will be provided as a resolution is found.

Current Workaround

If you encounter this issue, we recommend a daily reboot of the TCC 2. The API command for rebooting is available in the TCC 2 API documentation.
