When enabled, this function routes the audio stream to external Dante® speakers and disables the TC Bar's internal speakers

Known Issues

General

When using static IP addresses, performing a factory reset on the device will let the
devices disappear after claiming. Please click the “Refresh list” button in the device
list to rediscover the device.
Stopping the running Control Cockpit (CC) service via TrayApp takes comparably
longer if CC is open in the browser.
As the Control Cockpit user interface is protected by SSL encryption by default, a
warning message may appear on the first start. This occurs because the certificate
used for the encrypted connection is self-signed and created locally on your
computer. The web browser is not able to verify the certificate authority. Alternatively, you can use your own trusted certificate for the connection. For details, see the
website: security information or upload the files directly in the installer.
When configuring the proxy, only the http scheme is allowed as an authentication
method.
Firmware updates of devices may only be started from multiple selections of unique
product types due to a restriction on mixed multiple selections.
We recommend clearing the browser cache after the update. Under certain conditions
the browser may keep old user interface elements in its cache. Especially, updating
from Control Cockpit Version 1.0.0 requires manually clearing the web browser cache.

Evolution Wireless

EW-DX EM with secure firmware (4.0.0 or later):

When switching from ‚Fixed IP‘ to ‚Automatic IP‘ mode, the device may not reappear
online automatically after a network reset. Please click the „Refresh list“ button in the
device list to rediscover the device.
After initiating a factory reset, the device may still appear online in Control Cockpit
until the reset is complete. Once finished, the device will remain online and appear as
unclaimed. This also applies when the reset is triggered from the device display.
If a network cable is unplugged while in Dante® Audio redundancy mode, the device
display may continue showing the previous IP address. However, Control Cockpit will
display 0.0.0.0 for IP, Subnet, and Gateway.
On Dante-enabled devices, changing Dante® Network Mode and performing a factory reset may take up to one minute to complete.
Changing the IP modes for both primary and secondary Dante® network settings in a
very short time may prevent the last change from being applied.
Booting non-Dante® devices without a network connection can take up to one minute.
Sometimes, when connecting to the network, the device may take a while and show a
Link-Local IP address before obtaining a valid IP.
When switching between Dante® Network Modes „Single Cable“ and „Split Mode“, the device may appear offline and online multiple times in Control Cockpit as it completes
the network reboot process.

EW-DX EM 2 Dante:

After a factory reset the device details labels are greyed out. The function for editing
the device, the channel or the location is disabled. Please restart the device or Control
Cockpit Service to resolve the problem.
After powering on EW-DX EM 2 Dante devices, their values for “Dante® Primary
Settings”, Dante® Secondary Settings” and “Network Mode” cannot be saved for the
first 40 seconds. During this time, the IP address of the Dante® device is grayed out
in the “Device List” and the inline-edit of the device “Name” and “Location” are not
editable in the “Device” details page. After the first 40 seconds, it takes 3-5 seconds
for a change in Dante® settings to be saved. If the Sennheiser Control Cockpit v9.0.0
3/13 Sennheiser Control Cockpit Release Notes user changes other Dante® settings
within these 3-5 seconds, they will not be saved.
The “OK” button remains disabled when editing channel settings after a custom
frequency is set. Please select another channel to re-enable the “OK” button.

EW-DX EM 4 Dante:

After a factory reset, the device details labels are grayed out. The editing function for
the device, channel or location is deactivated. Please restart the device or Control
Cockpit Service to resolve the problem.

CHG 70N-C (firmware 3.0.0):

The user needs to wait several minutes to perform a second firmware update
(restarting the device does not reset this value).
A maximum of 10 cascaded chargers are allowed for simultaneous firmware updates.

ew G3/G4:

Operation of evolution G3 and G4 devices are limited to either one Sennheiser Control Cockpit installation or third party control.
Evolution G3 and G4 devices can only connect within local subnets.

TeamConnect

TCC 2:

When a TCC 2 is configured with a fixed IP and mDNS is off, enabling mDNS and
switching the IP mode to automatic will require the TCC 2 to be manually added again
using its IP address.
For TeamConnect Ceiling devices, the ‘Location’ field entry must be set. An empty
field cannot be saved.
In demo mode, the ‘Zone’ functions of the TeamConnect Ceiling 2 devices cannot be
edited.

TCC M:

After a factory reset of an existing TeamConnect Ceiling Medium device, the device’s
factory name and locations will not be displayed until the device is reclaimed.
If a TCC M has already been claimed, the “Identify” function will not work if attempted
before claiming the device. No UI feedback will be provided. Please claim the device
first before using the “Identify” feature.
The device access password cannot be changed for multiple devices at the same time
in a multi-selection scenario.

TC Bar:

When connecting both ports of the TC Bar M to a common switch, there is a risk
of creating loops. Make sure your TC Bar M is always connected to two different
networks that do not run via a common switch. For more details see chapter Network
Loops of the user manual.
If the IP of the TC Bar is grayed out or the TC Bar cannot be controlled via Control
Cockpit, the control service may not be accessible, a restart of the TC Bar is
recommended.
The setting of the sound profile in Control Cockpit has no influence on audio
streaming via Bluetooth (A2DP profile).
If you deactivate the Dante® protocol via Control Cockpit, the TC Bar must be
restarted to completely terminate the audio stream.
The license information for already claimed TC Bar devices can not be retrieved.

SpeechLine

After (re-) discovering SLDW/MCR devices, the device status can sometimes be
displayed as “offline”. Please reload the page and if the problem is not solved press
the “Refresh list” button to display the current device status.
