Neumann KH 750 DSP AES67 Subwoofer

Active DSP AES67 subwoofer

Neumann KH 750 DSP AES67

DSP POWER FOR ALL

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.

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.

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
  • Reproducing the “Sub” signal of a bass managed multichannel source
  • Working as an extension for KH line subwoofer systems
