Updating EW-DX EM 2 / EM 2 Dante / EM 4 Dante rack receiver

The latest firmware versions are available via the internal update server of the Sennheiser Control Cockpit.

CAUTION

As of firmware version 4.0.0, all control communication over the network is encrypted and authenticated

The devices are password protected and must be claimed in the control software before use (see Sound Control Protocol v2 (SSCv2) and Claiming devices).

The firmware version can then no longer be downgraded!

After the update, you will be able to set up the encryption method for the 3rd party access (see 3rd party media control access).

Please make sure that your firewall is configured correctly before you start the update. After the update, select the correct protocol for 3rd party providers to ensure that the integration of 3rd party providers is not broken. We recommend to update all 3rd party modules and use the new secure protocol.
