Description:

508296 Neumann KH 750 DSP D G Studio Subwoofer, 256W, Sennheiser

The compact KH 750 DSP is the 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.

In addition to its outstanding acoustic properties this DSP-based subwoofer offers functions for the Neumann monitors connected to its outputs regarding the interplay with the following tools:
- Automatic Monitor Alignment – Automatic room correction of stereo systems using the Neumann MA 1 measurement microphone (software for Mac/PC)
- Neumann.Control – Free iPad®-App for setup, operation, and room correction of stereo systems via guided and/or manual alignment

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.

APPLICATIONS:
Increasing the bass extension of the monitoring system
Increasing the maximum SPL of loudspeakers
Decreasing harmonic and intermodulation distortion of loudspeakers
Reproducing the LFE channel
