KH 420 ได้รับการออกแบบมาสำหรับการทำงานในระยะ 1.5 ถึง 3 ม. (5 "ถึง 9") มันจัดการกับพื้นที่นี้ได้อย่างง่ายดายด้วยพลังสำรองที่ยอดเยี่ยมและ การกระจายเสียงที่แม่นยำ แม้ในสภาพแวดล้อมทางเสียงที่หลากหลาย KH 420 ยังคงเป็นกลางและชัดเจนในทุกรายละเอียดจนถึงความแตกต่างเล็กน้อย ไม่มีการสูญเสียความละเอียดอ่อน ทุกองค์ประกอบเสียง

THE GOLD STANDARD IN THE MIDFIELD RANGE
The KH 420 is designed for a working distance of 1.5 to 3 m (5’ to 9’). It handles this space effortlessly thanks to great power reserves and precisely concentrated dispersion. Even in diverse acoustical environments the KH 420 remains neutral and clear in every detail down to the subtlest nuances. No subtlety is lost; every sound element can be localized.

The KH 420 is a three-way tri-amplified monitor with thermally protected Class AB amplifiers (330 W and two times 140 W). Just like the drivers, its Mathematically Modeled Dispersion™ (MMD™) waveguide is engineered for optimum precision. 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 dispersion of the KH 420 is deliberately designed to be narrower, to guarantee reference sound at longer working distances.

BEST WORKING ENVIRONMENT: CLOSE TO PROFESSIONAL EARS

The KH 420 is designed for midfield applications and as main monitor in project, music, broadcast and post-production studios for recording, mixing and mastering. And in a multi-channel system, it can also be freely combined with all other Neumann studio monitors.

PORTS AND HIGH DYNAMICS: NO LONGER A CONTRADICTION

With its tri-channel amplifiers the KH 420 also realizes sound pressures of up to 122.4 dB. And it thereby retains high-resolution and neutral representation across the entire frequency response. This also includes an exceptional bass response down to 26 Hz. Despite using ports, there is no “overhang” or audible resonance in the low frequency range and the transient response is precisely controlled at all times.

The computer modeled chassis is constructed of LRIM™ materials which eliminates standing wave resonances and suppresses intermodulation distortion, especially in the midrange.

For demanding treble, our own specially developed, powerful alloy fabric dome ensures distortion-free reproduction. The fabric dome captures the midrange with utmost precision. Its ultralight material and the powerful neodymium magnet enable a significantly better transient response with considerably less distortion than comparable midrange drivers.

DIGITAL INPUT AND DELAY OPTION

The Digital Input Module DIM 1 expands the loudspeaker electronics by a digital XLR input, a digital BNC input and a digital BNC output (192 kHz/24 Bit) for flexible digital signal links. With the delay function (adjustment range 0 - 400 ms) of the DIM 1, the audio signal can be delayed to ensure audio-visual synchronization (lip sync). In addition, the high resolution of the delays (0.1 ms) allows equalization of the propagation delays. The delay can be added to both inputs (digital and analog). The KH 420 can be retrofitted with a DIM 1.

HUNDREDS OF GOOD REASONS FROM THE NEUMANN PHILOSOPHY

The KH 420 has also 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 420, 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 420. 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.
