Powerful tri-amplified midfield studio monitor – high-precision dispersion with tremendous sound level reserves.
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. 
Features:
- Computer-modeled cabinet design using Low Resonance Integral Molding (LRIM™) materials
- Extraordinary bass depth (26 Hz) with high sound pressure (122.4 dB)
- Precise dispersion in the midrange and high frequencies
- As a stereo system with KH 750 DSP and optional tools, controllable and alignable to the room
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.
