Neumann KH120A Pair Bi-Amp studio monitors

Neumann KH120A Pair Bi-Amp studio monitor

• 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.
