KAT's new HD400 2.1 Hi-Definition Stereo PA Speaker System is the first amplification system of its kind. While it effectively delivers powerful PA functionality, the HD400 is optimized to reproduce the detail, punch and sonic range of the ever-expanding selection of digital instruments. The HD400 represents a great live sound solution for electronic drums, keyboard synths, DJ controllers, guitar synths, as well as VST computer software. Your instruments will jump into the spotlight with new brilliance and energy during live performances without sonic compromises. The HD400's microphone input also gives vocals a resounding burst of vibrancy that places them front and center. Advanced Components: With its impressive 400 watts of power and incredibly well balanced sound reproduction, the HD400 is as comfortable on stage as it is in the home or studio. And at peak power the HD400 will pump out an astounding 790 watts of high performance power. The three-component system includes a 15-inch premium quality subwoofer that dishes out beautifully punchy low end. Its cabinet is designed with a low shelf port to efficiently disperse low frequency energy and eliminate the distortion that typically accompanies ultra-low-end samples like 808 kicks.Ã¿The HD400's two satellite components include a 6-inch premium quality mid-range speaker and a one-inch tweeter with a wide dispersion neodymium compression driver for a rich and accurately detailed high- end. The HD400 system includes a pair of robust height adjustable, tripod speaker stands to elevate the satellite speakers as needed. Extensive Controls: No two playing environments are the same, so the HD400 includes powerful sound shaping front panel controls. High shelf and low notch filters allow you to tune and dial in your sound to optimize the acoustics of any room. The system input panel includes two sets of 1/4-inch stereo inputs, an XLR microphone input and an auxiliary stereo line input. For private practicing, there's a 1/4-inch headphone jack with independent volume control.Ã¿The HD400 also features full stereo signal processing DSP FX, including room and hall reverbs, chorus and delay. The integrated 3-band EQ allows fine-tuning to polish the overall sound.
