More about the KH 750 AES67
In conjunction with the MA 1 - Automatic Monitor Alignment software, which is available for Mac and PC, the entire system can be precisely calibrated to suit the room character. This includes the analog monitors connected to it, which can be perfectly adapted to the room by correcting both amplitude and phase via the powerful DSP integrated in the subwoofer.
The newly designed 10” long-throw driver has a strong linear working magnet system with ELFF™ technology (Extremely Linear Force Factor™). As subwoofers are usually placed on the floor, a robust grille protects the driver from accidental damage. The ultra-compact cabinet is a closed design, which ensures the fastest possible transient response. The two analog XLR inputs are balanced as are the two analog XLR outputs. The 192 kHz / 24-bit digital input can accept AES3 and S/PDIF signals. If no signal is present for more than 90 minutes, the auto bypass function reduces power consumption to 0.3 W.
The KH 750 AES67 can be used in music, broadcast, and post production studios for tracking, mixing, and mastering.

Advice
This device supports Sennheiser Sound Control (SSC) based on TCP and IPv6. The static IPv6 address of the device can be found using mDNS. For more information on SSC, please refer to the Sennheiser website (for example here).
Please note: We do welcome the community of users implementing custom control solutions for KH monitors based on SSC. However we do not offer technical support on using the protocol and the customer support organization will not address issues with custom monitor control applications or side effects Neumann applications. Using the SSC protocol outside the Neumann applications is done at your own risk. Neumann does not warrant SSC functionality outside of the MA 1 - Automatic Monitor Alignment Application. Future firmware releases may implement a different control protocol than SSC.
