Soundking DX20 - User Manual

The Soundking DX20 is a compact, full-featured digital mixing console designed for various applications, including performances, conferences, schools, intelligent buildings, industrial and mining enterprises, and personal use. It integrates high-end hardware with touch slide control and 485 operation, leveraging a fourth-generation 40-bit SHARC floating-point processor and 24-bit/192kHz A/D and D/A conversion. The console is equipped with a 7-inch HD IPS touchscreen with an adjustable angle, facilitating quick and intuitive operation.

Function Description:

The DX20 serves as a central hub for audio mixing and processing. It features 20 inputs, including 12 professional MIC inputs, 4 COMBO inputs, and professional digital signal inputs (S/PDIF, AES/EBU). It manages 16 buses, comprising 4 mono output buses, 5 stereo output buses, and 1 stereo monitor bus. The console incorporates 8 internal effect modules, including reverb, delay, modulation, and GEQ, allowing for comprehensive audio enhancement.

For output, it provides 8 custom assignable XLR output ports, stereo monitor outputs, and a headphone output. Control is enhanced with 4 multi-function custom buttons, 6 DCAs (Digitally Controlled Amplifiers), 2 mute groups, and 2 user-definable layers. Two USB ports are available for stereo recording and playback, system updates, and scene import/export. The console also supports scene memory and 485 control for external integration.
