Description

Neumann KH 750 AES67 Compact DSP-Controlled Closed-Cabinet Subwoofer

Designed to route audio over IP in an existing AES67 studio infrastructure, the Neumann KH 750 AES67 is a DSP-powered, 10" subwoofer capable of reproducing 18 to 750 Hz at SPLs of 105 dB. This model 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 includes the flexible 2.0 / 0.1 Bass Manager, so the sub can be implemented in many different scenarios. Use the KH 750 AES67 for the LFE channel in a 5.1 setup or as a sub in a conventional stereo mix position. The KH 750 AES67 can be easily integrated with Neumann's range of monitors and is suitable for use in mixing, mastering, music, and broadcast. The rear panel provides options to suit various configurations such as four different routing modes. Analog and digital I/O is on hand, as are fourth-order DSP crossovers and acoustical controls to integrate the sub into your room. Use the Automatic Monitor Alignment application (Mac and Windows) to precisely calibrate your monitor's amplitude and phase via the powerful DSP integrated into the subwoofer.

Applications

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

Compact Ultrastiff Wooden Cabinet

Tough painted finish and high-density rubber isolating feet
Excellent self-damping properties leading to minimal cabinet resonances
No standing wave resonances inside cabinet
Tight bass sound due to very low group delay
