Neumann KH 750 AES67 – DSP-Controlled Subwoofer with AES67 Input Neumann

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:

• Bass extension of a stereo monitoring system
• Increasing the maximum SPL of the loudspeaker system
• Decreasing harmonic and intermodulation distortion of the loudspeaker system
• Reproduction of the LFE channel
• Reproduction of the Sub signal of a bass managed multichannel source
• Extension for KH line subwoofer systems
• AES67/ST 2110 network integration

In conjunction with the Automatic Monitor Alignment, 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.
