Product Overview
Designed as the rightful successor to Neumann's KH805, the KH750 is the ideal choice for smaller rooms and smaller studio monitors. With its unique and flexible 2.0/0.1 Bass Manager this allows the KH750DSP subwoofer to be used in many different system configurations. The back panel features analog and digital inputs and outputs, four routing modes, fourth-order DSP crossovers and adaptable acoustical controls to allow for seamless system integration.
Available for order in late April, 2019 - the KH750DSP subwoofer is designed to complement Neumann’s extensive range of monitors, and can be used in music, broadcast, and post production studios for tracking, mixing, and mastering.
Via standard IP networking, Neumann.Control gives full access to all the functions of the KH750DSP Subwoofer that are not currently available via the back panel. Systems of loudspeakers can be defined, from mono to 3D, aligned for a good in-room sound, and then operated centrally: Setup, Align, Operate. At last, you do not need to be an expert to bring a subwoofer into a room, even a small room.
