Dual domain mode

In this mode, the Sennheiser control application and Dante Controller are in different networks and have different outgoing IP addresses. Outgoing data packages are tagged as VLAN (virtual local area network).

This mode is generally used if you receive a combined data flow from two separate networks through a single network line and want to split this combined data flow into two different IP and MAC addresses again. Doing so lets you operate the Dante® network and the control network independently of one another using the same switch.

Outgoing Dante® data packages are tagged as VLAN (virtual local area network) according to the standard 802.1q. The incoming data packages must also be tagged by the externally connected network so they can be properly assigned for internal use. Depending on the device, the data packages must be translated from the outgoing 802.1q standard to 802.3 using a managed switch.

Please note that VLAN tagging must be active in the Sennheiser control application (see Activating tagged VLAN (Dante® network)).
Use this mode if you want to:

  • Configure both the Dante® and the control network using a switch

  • Use two different IPs to address the control network and the Dante® network separately

  • Control both networks using a single network connection of the TC Bar.

Simplified network diagram for the TC Bar S:

  • In this mode, the TC Bar S receives two different IP addresses.
  • One IP is used to address the TC Bar through the control application.
  • The other IP is used to address the TC Bar through the Dante Controller.


Simplified network diagram for the TC Bar M:

  • In this mode, the TC Bar M receives two different IP addresses.
  • Both Ethernet ports can be used to address the TC Bar through both the control application and the Dante Controller. In this case, one IP is available for Dante® and one IP for the application.
  • Any connected enhancements can be managed using the Dante Controller and the control application because the TC Bar M forwards the signals using the integrated switch.
  • When a Dante Controller is used, the data packages are also tagged as VLAN (see Activating tagged VLAN (Dante® network)).
Always make sure to connect the TC Bar M to two different networks that do not run through a common switch (see Danger of network loops). Otherwise, there is a danger of a network loop occurring.


Alternative connection option:

The enhanced devices (e.g., TCC M or MCR) are not connected using the second Ethernet port. Instead, they are connected by an external switch using separate cabling.
