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.

HUNDREDS OF GOOD REASONS FROM THE NEUMANN PHILOSOPHY

The KH 310 has been developed true to the Neumann philosophy for monitor loudspeakers. Every component, every shape, every signal and every wave motion is a consequence of this philosophy. No form or component is there without reason. There are hundreds of tangible reasons built into the KH 310, which all stand for exceptionally pure and neutral sound. These include, for example, curvatures of the housing that reduce edge diffraction. Also included is the pistonic output of the bass driver which does not give rise to harmonic distortions, even with the highest sound peaks. Some of these reasons are obvious in the KH 310. Others Neumann prefers to keep to itself. But together, each can be heard – sound professionals in both large and small studios all around the world can testify to this.
