The Neumann KH 420 G is is a three-way active monitor designed for use as a mid-field or main monitor, and can be used free-standing or flush mounted into a wall. It is particularly well-suited for use in music, broadcast, and post production studios for tracking, mixing and mastering, and in multi-channel systems can be mixed freely with other loudspeakers in the range.

The Neumann KH 420 G is designed for a working distance of 1.5 to 3 m. 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.

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.

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.
