Precision redefined
The KH 120 is Neumann's trailblazer model and development yardstick for compact studio monitors.
It has been a reference class for close-range monitoring since 2011.
Enormous power reserves meet high-precision sound conduction. The result: Maximum signal fidelity
and distinctly contoured transients across the entire, neutrally designed frequency response.
This enables you to precisely control tonal depth, spatial image and even the smallest details in the mix.
The KH 120 is a two-way bi-amplified monitor with thermally protected class-AB amplifiers (80 W each).
Just like the drivers, its Mathematically Modeled Dispersion™ (MMD™) waveguide is calculated with an
optimal level of precision. Sound distributed in a horizontally precise manner ensures flexibility
in the listening position; the narrower vertical dispersion reduces the negative effects of
nearby reflections – for example from a desk or mixing console. The finely controlled dispersion
characteristics optimize reproduction in even the most varied of room configurations.
Best working environment: Close to professional ears
The KH 120 is typically used in near-field applications such as project, music, broadcast and post-production
studios for recording, mixing and mastering. It it also available as a digital input “D” version.
Ports and high dynamics: No longer a contradiction
With its digital switched-mode power supply and bi-amplification, the KH 120 realizes sound pressure
of up to 111.1 dB and in doing so, retains a high-resolution and neutral representation across the entire
frequency response. This provides sufficient energy for maximum dynamics without distortion and losses.
As a result, the bass goes down to impressive 52 Hz. Despite using ports, there is no “overhang”
in the bass response. The transient response remains well in control. The optimized design of the drivers
delivers clean sound right down to the lowest parts of the 50 Hz region. This rich foundation offers
enough room to work cleanly on the mix without the necessity for a supplementary subwoofer.
In the demanding treble range, the specially developed, powerful alloy fabric dome ensures
distortion-free reproduction.
The perfect complement: The KH 750 DSP subwoofer
In addition to its outstanding acoustic properties this subwoofer offers functions for non DSP-based Neumann
monitors connected (analog) 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
