EXPANDED MIDRANGE PRECISION – DRY BASS SOUND
With its specially designed midrange driver, the compact KH 310 is particularly suited for precise work with speech, vocals, guitars and other instruments that have a midrange emphasis. Its closed design enables a very fast transient response. The associated low harmonic distortion guarantees a neutral reference sound to meet the highest standards.
The KH 310 is a three-way tri-amplified monitor with thermally protected Class AB amplifiers (210 W and two times 90 W). Its Mathematically Modeled Dispersion™ (MMD™) waveguide delivers sound waves into the room with superior accuracy. The drivers are modeled using Neumann’s in-house developed software, which reduces non-linear distortion in every situation. 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 precisely controlled dispersion characteristics optimize reproduction in different room configurations and the response is extremely adaptable through various acoustical control settings.
