The KH 420 represents the result of using the latest techniques in acoustical, electronic and mechanical design to bring a new benchmark in audio reproduction quality. In-house computer optimized drivers, a waveguide featuring mathematically modeled dispersion (MMD), flexible acoustical controls, various input options and an extensive mounting hardware range allow the KH 420 to be used in diverse acoustical conditions, with any source equipment, and in a wide variety of physical locations.

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

The Optional 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.
