Neumann KH750 DSP Active DSP Subwoofer, 10" driver - B-Stock

The Neumann KH750 is an active DSP sub-woofer is a studio quality sub that features a 10" driver, deep bass response and DSP engine optimizes output to achieve reference class sound. The compact KH 750 DSP is the ideal choice for smaller rooms and smaller studio monitors, such as the KH 80 DSP. It has a unique and flexible 2.0/0.1 Bass Manager allowing the sub-woofer to be used in many different system configurations.

This is a B-Stock Item. 

On the back panel there are analog and digital inputs and outputs, four routing modes and adaptable acoustical controls to allow for seamless system integration. The Neumann.Control software gives access to many additional functions inside the sub-woofer. The KH 750 DSP can be used in music, broadcast, and post production studios for tracking, mixing, and mastering.

The newly designed 10” long-throw driver has a large magnet, linear motor design and a very stiff pressed steel basket. As subwoofers are usually placed on the floor, a robust grille protects the driver from accidental damage. The well-braced cabinet is a sealed designed which brings the fastest possible transient response. The two analog XLR inputs are balanced as are the two analog XLR outputs. The 192 kHz / 24-bit digital input can accept AES3 and S/P-DIF signals. There is a bypass able standby function and the switch-off time can be adjusted in Neumann.Control.
