Studio Monitor

From Neumann:

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.

The KH 310 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.
