In terms of the acoustic design, the newly developed 10-inch ultra-long excursion woofer features a linear magnet system with Extremely Linear Force Factor (ELFF) technology.
German studio specialist Neumann.Berlin has launched KH 750 AES67 subwoofer, a product variant of KH 750 DSP for AES67-based environments.
With its DSP power, the KH 750 AES67 is far 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, even the connected analogue Neumann loudspeakers – in amplitude and phase.
Commenting on the new launch, Markus Wolff, Portfolio Manager, Neumann, said: “The compact KH 750 AES67 is the ideal subwoofer for all 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 allows to address not only the subwoofer but the entire stereo system, including the speakers connected to the KH 750 AES67. 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 KH 750 DSP have been retained, along with other features including the bass manager with four routing modes, flexible acoustical controls for a wide range of configurations, setup conditions, as well as analogue and digital inputs and outputs.
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 also includes the monitors connected to it, whose amplitude and phase frequency responses are perfectly corrected and adapted to the monitoring environment. This makes the KH 750 AES67 compatible with all KH-Line analogue monitors including the KH 120, KH 310, and KH 420, as well as Neumann’s DSP-based monitors such as the KH 80 DSP.
In terms of the acoustic design, the newly developed 10-inch ultra-long excursion woofer features a linear magnet system with Extremely Linear Force Factor (ELFF) technology. Despite its compact dimensions, the KH 750 AES67 provides bass extension down to 18 Hz. As the subwoofer relieves the connected monitors of much of the low-frequency reproduction, intermodulation distortion is drastically reduced, and the maximum sound pressure level is increased. By adding another KH 750 AES67, even larger systems may be realised.
Ralf Oehl, CEO of Neumann, added: “The new KH 750 AES67 is Neumann’s entry into the continuous support of AES67 networks. It raises the entire 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 linearize and room-align amplitude and phase via the revolutionary MA 1 system for sound reproduction with unprecedented precision. It is, without exaggeration, 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.”
