KH 80 DSP
Studio Monitor
From Neumann:
With its digital core, the KH 80 DSP enables filtering functions and room adjustment options, which brings reference level reproduction to any environment. Even with its compact design, it has extraordinary reserve capacity - as well as the classic strengths of the Neumann monitor philosophy: clearly defined dispersion angle, distortion-free design and sophisticated material selection.
The Neumann developers know every nuance, every angle and every wave reflection of the KH 80 DSP. It sounds so pure because they are directing every sound wave so precisely. The KH 80 DSP’s design is based on computer simulations that calculate with a level of accuracy that no one other than Neumann does. The Mathematical Modeled Dispersion Waveguide (MMD™) provides the studio series with a solid base for precise sound direction that remains unique. Maths has never sounded so good.
It might be a project studio, an outside broadcast van, a corner at work or just a brick building: The room defines the sound. Surfaces and corners in the room cause interference, diffraction, reflection, and refraction: all are forms of distortion. For a really true sound, without acoustic-physical “accidents”, you normally need expensive equipment plus plenty of time and expertise to align it correctly – or smart algorithms. An easy adjustment to the monitor position (free standing, small/medium/large desk) is possible via the rear "Acoustical Control" switch.
