Product Introduction：

Audio Input: Dual-source Compatibility & Flexible Switching

Equipped with versatile professional audio input ports, the VK6 supports both analog and digital sources to fully meet connection demands across all common KTV applications. For music input, it features 2 pairs of RCA analog stereo inputs plus optical digital stereo input for full dual-format coverage with seamless source switching, compatible with song players and media devices. Two independent TRS analog microphone inputs accommodate duets and host-singer combinations; each channel supports separate parameter tuning for customized vocal optimization.

Audio Processing: Multi-parameter Fine Tuning for Enhanced Sound Quality 
 

The VK6 features an all-round audio processing architecture covering music input, microphone pickup and final output to deliver studio-grade acoustics via layered sound optimization.
•Music Processing: Built-in dedicated bass boost, high-pass filter and 7-band parametric EQ for precise tuning per music genre and source, restoring authentic musical texture and enriching low-frequency performance.
•Mic Processing: Integrated vacuum tube timbre emulation, 10-level noise gate, frequency shifting, high/low-pass filters, compressor and 15-band parametric EQ to eliminate unwanted noise and fix frequency deficiencies, endowing vocals with warm timbre and superior singing expressiveness.
•Vocal Effect: Adjustable professional echo and reverb generate natural spatial ambiance for immersive karaoke and enhanced vocal presence.
•Output Processing: Mixer, variable high/low-pass filters (6dB~24dB/Oct), up to 80ms delay and 7-band parametric EQ work alongside DEL dual-engine limiter. It delivers refined output tuning while providing full-range overload protection to preserve sound quality and speaker lifespan.
 

Control Method: Multi-connection for Efficient Professional Operation

Controllable via user-friendly PC GUI software with multiple connection options: driver-free USB, RS232, Wi-Fi and wired LAN (with optional expansion module), enabling fast on-site debugging and remote management. The built-in innovative real-time RTA acoustic analysis precisely measures output signals and room acoustics to accelerate troubleshooting and sound calibration for audio engineers. The software supports Chinese/English language toggle with visualized professional parameters for intuitive user operation.

Hardware Design: Professional & Durable Construction

Standard 1U rackmount dimension: 44 × 483 × 178 mm for space-saving standardized cabinet installation. Rated for 220VAC ±10% input with only 20W low power consumption, ensuring stable long-hour continuous operation for commercial KTV usage. Six balanced XLR analog outputs suppress signal interference for stable audio transmission. Independent RCA outputs for lighting-trigger music signal and voice ordering mic signal enable synchronization among sound, lighting and song-request systems to elevate overall KTV experience.
