Neumann has expanded the KH line with its first midfield monitor, the new KH 420, an active 3-way system (10-inch + 3-inch + 1-inch) well suited for larger 5.1 and 7.1 configurations and listening distances of up to 11 meters (more than 30 feet).
The KH 420 is specified as provided a 26 Hz corner frequency, a whole octave lower than the KH 120. For even lower bass reproduction for surround systems with a dedicated LFE channel, users can add the KH 870 woofer to extend the response down to 18 Hz.
The KH 420 also offer computer-optimized drivers, a proprietary Mathematically Modeled Dispersion Waveguide (MMD), acoustical controls for matching the loudspeakers to the listening room, a highly flexible input section, and a wide range of mounting hardware.
It has been designed to provide optimum dispersion regardless of the orientation of the cabinet due to a rotatable waveguide section which contains both the high frequency and midrange drivers.
An optional Digital Input Module (DIM 1) will be available for the KH 420, which provides the monitor with digital AES3 and S/P-DIF inputs and a delay function. This feature, which is available on both the digital and analog inputs, may be used for audio/video lip synchronization and to compensate for non-equidistant speaker placement. Maximum delay time is 409.5 ms with a minimum resolution of 0.1 ms.
“The KH 420 delivers an accurate picture of the tonal nuances of the original recording,” says Wolfgang Fraissinet, president of Neumann.Berlin. “In order to deliver a perfect stereo image, the KH 420 pushes the boundaries of what is possible in terms of linearity, performance and close production tolerances. It reflects the quality-driven approach that Neumann.Berlin has been committed to for many decades”.
