Neumann KH 750 DSP Subwoofer

Neumann KH 750 DSP Subwoofer Product Details

Description

The extremely compact Neumann KH 750 DSP is the ideal choice for smaller rooms and smaller studio monitors such as the KH 80 DSP. It features a uniquely flexible 2.0/0.1 Bass Manager that allows the subwoofer to be used in many different system configurations. The rear panel features analog and digital inputs and outputs, four routing modes, and flexible acoustic controls for seamless system integration. The Neumann Control software provides access to many additional functions of the subwoofer. The KH 750 DSP can be used in music, broadcast and post-production studios for tracking, mixing and mastering.
