The Sennheiser TC Bar can operate as a standalone conferencing device via USB-C. In professional AV systems, it also supports network connectivity, Dante, and centralized management through Sennheiser Control Cockpit. This makes it suitable for meeting rooms that require network-based device management or integration with other Sennheiser microphones.
It is important to note that TC Bar S and TC Bar M have different network architectures. As a result, Dante and control network integration differs between the two models.
How does the Sennheiser TC Bar connect to Dante and Control Cockpit?
When used as a network solution, the TC Bar is first assigned to a Sennheiser Control Cockpit system. The device can then be managed through the software's web interface instead of being used only as a USB-C device connected directly to a computer.
By default, both the TC Bar S and TC Bar M use Single Domain Mode. In this mode, Dante and the Control network share the same network infrastructure, while the specific implementation depends on the number of network connections available on each model.
TC Bar S has a single network connection. Therefore, Dante and Control traffic are combined over the same connection. When adding Sennheiser Microphones via Dante and devices running Control Cockpit, a network switch is required to connect the devices appropriately.

In comparison, TC Bar M has two network connections. One port can be used to manage the TC Bar over the network, with Dante Controller and Control Cockpit connected through a switch. The second port can be used to connect additional Sennheiser microphones via Dante, such as the TeamConnect Ceiling Medium (TCC M). With this configuration, only one Ethernet cable is required for the additional Microphone connection as described by Sennheiser.

TCC M can then also be managed within the same system through Control Cockpit or Dante Controller. This allows the TC Bar to become part of a networked conferencing audio system rather than operating as a standalone device.
How do the TC Bar S and TC Bar M separate Dante and the Control network?
In systems that require the Dante network and Control network to be separated, the differences between the two models become more apparent.
With TC Bar S, the device has only one network connection, so Dante and Control cannot be physically separated through two dedicated ports. Instead, Sennheiser allows the networks to be logically separated using VLAN tagging. Users need to select Dual Domain Mode in Control Cockpit to configure this setup.
With TC Bar M, the two network connections allow Dante and the Control network to be physically separated. Users can enable SPLIT Mode to use two separate network connections. According to Sennheiser, this mode is also used with devices such as Multi-Channel Receiver (MCR) and TeamConnect Ceiling Medium.
Another important point when deploying a Sennheiser TC Bar with Dante is that Bluetooth, Wi-Fi and Dante are disabled by default when the device leaves the factory for security reasons. These functions must be enabled through Sennheiser Control Cockpit before use.
With Sennheiser ceiling Microphones, the TC Bar can also handle part of the signal processing without requiring a third-party DSP. When a ceiling microphone is connected to the TC Bar, the system provides auto-mixing and multi-AEC (Acoustic Echo Cancellation). Sennheiser also confirms that the TC Bar supports multi-echo suppression when using external microphones.
Overall, deploying the TC Bar with Dante and Control Cockpit can scale from a standalone meeting room to a networked conferencing system using ceiling Microphones. TC Bar S is suited to architectures where Dante and Control are handled over a single network connection with VLAN-based logical separation, while TC Bar M provides an additional option for physical network separation through its two network connections.
