Neumann KH-750 Active DSP 10-Inch Subwoofer
Neumann KH-750 Active DSP 10-Inch Subwoofer
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.
