Neumann KH-750-AES67 10-Inch Active DSP Subwoofer with AES 67 Input - Anthracite Metallic

The compact KH 750 AES67, as 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 model variant offers newly integrated redundant AES67 audio network ports that are fully compliant with broadcast standards such as ST 2110 and ST 2022-7 redundancy. At the same time, the KH 750 AES67 is compatible with DANTE®-generated AES67 network streams.

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

Features:

• Redundant AES67 audio network interface
