Neumann KH 750, Active DSP Subwoofer, 10" driver, 48.4 liters, 256 W, 105 dB SPL
Vendor: Neumann
Neumann KH 750, Active DSP Subwoofer, 10" driver, 48.4 liters, 256 W, 105 dB SPL, 18 - 300 Hz, metallic anthracite. Includes (1) KH 750 DSP D G and (3) Mains cables (EU, UK, US)
The Neumann KH 750 is the best and 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. Also, the optional Neumann.Control iPad®app gives access to many additional functions. This also includes the possibility of aligning Neumann monitors, that are connected to the subwoofer, to the room using the patented "Guided Alignment" and controlling the entire stereo system. It also includes analog monitors.
MORE ABOUT THE KH 750 DSP
The newly designed 10” long-throw driver has a strong linear working magnet system with ELFF™ technology (Extremely Linear Force Factor™). As subwoofers are usually placed on the floor, a robust grille protects the driver from accidental damage. The ultra-compact cabinet is a closed design 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 bypassable standby function and the switch-off time can be adjusted in the Neumann.Control iPad® app. The KH 750 DSP can be used in music, broadcast, and post production studios for tracking, mixing, and mastering.
