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.
Best working environment: Close to professional ears
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.
A solid bass foundation, high impulse fidelity
With its powerful switched-mode power supply and tri-channel amplifiers, the KH 310 realizes sound pressure
of up to 116.3 dB and thereby retains a high-resolution and neutral representation across the entire frequency response.
This provides sufficient energy for even the most demanding impulse dynamics with no distortion or losses.
The bass goes down to an impressive 34 Hz.
The closed cabinet design means a lower group delay. This results in almost the entire frequency range being
reproduced at the same time; the transient response is precisely controlled at all times.
Ultralight fabric dome optimizes midrange reproduction
The optimized design of the driver enables a pristine sound right down to the lowest bass regions.
For most applications, the rich foundation offers enough bass extension to work cleanly on the mix without
the necessity of a supplementary subwoofer. For demanding treble sounds, our own specially developed,
powerful alloy fabric dome ensures distortion-free clarity in the high-frequency range.
The fabric midrange dome captures the middle frequency range with the utmost precision.
Its ultralight material and the powerful neodymium magnet enable a significantly better transient
response with considerably less distortion than comparable midrange domes.
