Neumann KH 750 AES67 Subwoofer

German studio specialist Neumann.Berlin presents the KH 750 AES67 subwoofer, a product variant of the highly acclaimed KH 750 DSP for AES67-based environments. Thanks to its DSP power, the KH 750 AES67, too, is more than “just” a subwoofer. It also provides access to Neumann’s Automatic Monitor Alignment MA 1, thus allowing for room adaptive correction of the entire monitoring system, including connected analogue Neumann loudspeakers.

The compact KH 750 AES67 is designed for areas in which audio over IP in existing AES67 infrastructure is to be routed all the way to the loudspeakers in a redundant and lossless manner. “Its AES67 interface addresses not only the subwoofer but the entire stereo system, including the speakers connected to the KH 750 AES67,” explains Portfolio Manager Markus Wolff. “Its dual AES67 audio network connections are fully compliant with broadcast standards such as ST 2110 and ST 2022-7 redundancy. At the same time, the KH 750 AES67 is also compatible with DANTE-generated AES67 network streams.”

The acoustic properties of the successful KH 750 DSP have been retained, as well all other features, such as the unique Bass Manager with four routing modes, flexible acoustic controls for a wide range of configurations and setup conditions, as well as analogue and digital inputs and outputs. The KH 750 AES67 also features a powerful DSP engine.

In combination with the Automatic Monitor Alignment – MA 1, which is available for Mac and PC, the entire monitoring system can be precisely calibrated to suit the specific room character. This includes the monitors connected to it, whose amplitude and phase frequency responses are corrected and adapted to the monitoring environment. This makes the KH 750 AES67 the ideal complement to all KH-Line analogue monitors such as the KH 120, KH 310, and KH 420, as well as to Neumann’s DSP-based monitors such as the KH 80 DSP.

Deep Bass, Small Space

The newly developed 10-inch ultra-long excursion woofer features a powerful, linear magnet system with ELFF technology (Extremely Linear Force Factor). Despite its compact dimensions, the KH 750 AES67 provides bass extension down to 18 Hz. Because the subwoofer relieves the connected monitors of much of the low frequency reproduction, intermodulation distortion is reduced, and the maximum sound pressure level is increased. By adding another KH 750 AES67, even larger systems may be realised.

“The new KH 750 AES67 is Neumann’s entry into the continuous support of AES67 networks. It raises the monitor system to a new level: deeper bass, higher SPL capability, and even greater sound transparency. In addition, the integrated DSP engine makes it possible to linearise and room-align amplitude and phase via the revolutionary MA 1 system for sound reproduction with precision,” summaries Neumann’s CEO Ralf Oehl. “It is the beginning of a ‘new era’ in Neumann monitoring ­­– which is finally making its way into AES67-based environments such as broadcast studios. More products are to follow.”
