DSP power for all

The compact KH 750 DSP is the ideal choice for smaller rooms and smaller studio monitors. It has a unique and flexible Bass Manager (2.0/0.1), analog and digital inputs, four routing modes and adaptable acoustical controls to be used in many different configurations.

In addition to its outstanding acoustic properties this DSP-based subwoofer offers functions for the Neumann monitors connected to its outputs regarding the interplay with the following tools:

Automatic Monitor Alignment – Automatic room correction of stereo systems using the Neumann MA 1 measurement microphone (software for Mac/PC)
For the alignment of multichannel setups, we offer the multichannel option for the MA 1 software.

This also applies to all non DSP-based Neumann monitors connected (analog) to the KH 750 DSP, which enables them to make use of the subwoofer’s DSP power.
