Neumann KH 310 D L G, Active Near-field Monitor, left version, 8" + 3" + 1" drivers, magnetically shielded
Vendor: Neumann
Neumann KH 310 D L G, Active Near-field Monitor, left version, 8" + 3" + 1" drivers, magnetically shielded, additional BNC / XLR 192 kHz digital inputs and delay feature, 16.2 liters, 210 + 90 + 90 W, 116.3 dB SPL, 34 - 21k Hz, metallic anthracite
The metallic anthracite color of Neumann KH 310 D L G makes it unique, also it has a specially designed midrange driver, the compact Neumann KH 310 D L G is particularly suited for precise work with speech, vocals, guitars and other instruments that have a midrange emphasis. The Neumann KH 310 D L G closed designed allows a very fast transient response. The associated low harmonic distortion guarantees a neutral reference sound to meet the highest standards. Also, the Neumann KH 310 D L G has a three-way tri-amplified monitor with thermally protected Class A B amplifiers (210 W and two times 90 W). Neumann KH 310 D L G has a Mathematically Modeled Dispersion ™ (MMD™) waveguide that can delivers sound waves into the room with superior accuracy.
The Neumann KH 310 D L G drivers are molded using Neumann's in-house developed software, which reduces non-linear distortion in every situation. Sound distributed in a horizontally precise manner that 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. Another unique features of the Neumann KH 310 D L G is the precise controlled dispersion characteristics optimize reproduction in different room configurations and the response is extremely adaptable through various acoustical control settings.
