KH 870 II AES67 - Overview

Powerful Reference-Quality Sub for Immersive Systems

The KH 870 II AES67 is the perfect subwoofer for larger rooms, providing powerful bass extension with Neumann precision. It includes a unique and flexible Bass Manager for stereo, surround and immersive systems up to 7.1.4. Analog and AES3 outputs (BNC) for up to 11 studio monitors as well as redundant AES67 network connectivity allow for flexible connectivity.

Next Generation Subwoofer
The KH 810 II AES67 improves on its predecessor in acoustic performance and adds new features. Thanks to a novel long-throw 10" woofer with Extremely Linear Force Factor (ELFF™) technology and intelligent protection limiters, the KH 810 II ensures exceptionally low distortion even at maximum SPLs.

The KH 810 II AES67 extends low frequency reproduction down to 16 Hz and delivers about twice the output of the KH 750 DSP. This makes the KH 810 II AES67 the perfect complement to mid-sized speakers such as the KH 150 and KH 310.

The KH 810 II AES67 is DSP-controlled for superior sonic performance and seamless integration via MA 1 Automatic Monitor Alignment (sold separately). When combined with analog Neumann studio monitors such as the KH 310, or KH 420, it offers sufficient DSP-power for aligning an entire stereo, surround or even immersive system up to 7.1.4, using MA 1, optimizing not only the frequency response but also the phase. In surround and immersive systems, analog and DSP-equipped Neumann speakers can be combined and room-aligned using MA 1 with Multichannel Extension (sold separately).

With its redundant AES67 connectivity, this subwoofer is a complete solution for integrating your entire loudspeaker setup into your Audio over IP infrastructure. The KH 870 II AES67 accepts up to 12 channels of network audio to be reproduced by the subwoofer itself and up to 11 studio monitors connected to its analog and digital outputs.

Precision in Every Detail
The rigid cabinet features a highly efficient bass reflex system, which is carefully engineered and tuned for the tightest bass reproduction - with inaudible port noise.

Two analog XLR inputs and outputs are available to connect the subwoofer for stereo operation. For multichannel operation, the KH 810 II AES67 offers two Sub D25 connectors for analog connection as well as seven AES3 outputs (BNC) for digital connection to 11 studio monitors. All analog inputs and outputs are electronically balanced. The AES3 outputs (BNC) are compatible to S/P-DIF inputs on Neumann studio monitors using a BNC to RCA cable.
