The KH 750 DSP subwoofer
Thank you for purchasing a Neumann subwoofer. Neumann subwoofers are designed to com-
plement Neumann’s extensive range of monitors. They can be used in music, broadcast, and
post production studios for tracking, mixing, mastering, and home recording. They can be
positioned away from a wall, next to a wall or in a corner and can be mixed freely with other
loudspeakers and subwoofers from the Neumann Studio Monitor Systems range.
The built-in 2.0 / 0.1 Bass Manager can be used in many ways as there are four routing modes
to ensure maximum flexibility when using the subwoofer - see “Uses” below. Fourth order
crossovers and flexible acoustical controls allow for seamless system integration and the bass
management function can be remotely controlled.
State-of-the-art circuitry design and the specially developed long excursion bass driver have
been used to ensure the most accurate sound reproduction possible. Neumann products are
designed for longevity so we hope you enjoy many happy years of using this product.
Uses
Bass extension for loudspeakers
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 810, KH 870 and KH 805 subwoofer systems
Making a Plane Wave Bass Array™ system
Improving the modal behaviour of the room due to optimal placement of the subwoofer in
the room.
