Powered Studio Subwoofer 256W with 10" Driver, DSP and AES67 Connectivity

The compact KH 750 AES67, a product variant of the KH 750 DSP, is the ideal subwoofer for routing audio over IP in an existing AES67 studio infrastructure all the way to the loudspeakers in a redundant and lossless manner. It thus serves as the link between the studio's digital ST2110/AES67 data stream and all KH line monitors. By adding more KH 750 AES67 subwoofers, stereo systems of any size can be realized. The KH 750 AES67 adds AES67 connectivity and retains all other features of the KH 750 DSP such as the unique and flexible Bass Manager as well as analog and digital inputs, four routing modes, and adaptable acoustical controls to be used in many different configurations and setups.

The KH 750 AES67 thus enables all pairs of KH line monitors to be integrated into a redundant AES67 IP network.

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.
