Product Introduction：

Newly released by Leimeng Technology, the VK3D is a custom-engineered audio processor exclusively for KTV venues. Centered on vacuum-tube microphone timbre and music bass enhancement, it perfectly solves two common KTV pain points: thin, lifeless vocal performance and weak low-frequency output from compact speakers. Featuring robust hardware and user-friendly operation, it optimizes singers’ experience while simplifying store maintenance, effectively upgrading sound quality and karaoke enjoyment in every private room.

To fix the prevalent issue of harsh, dry and texture-lacking microphone sound, the VK3D adopts advanced DSP algorithms to emulate iconic vintage vacuum tube tonal characteristics, endowing vocals with warm, enveloping texture and greatly boosting singing comfort.

For typical KTV rooms with limited space and compact loudspeakers, its psychoacoustics-based bass enhancement extends low-frequency response and boosts dynamic headroom. Even small-sized speakers deliver punchy low-end with tangible rhythmic vibration and immersive musical atmosphere.

The VK3D is equipped with professional-grade M-DSP processor paired with latest ESS AD/DA converter: the M-DSP smoothly handles concurrent heavy-load computing of tube emulation, reverb and bass boost with ultra-low latency down to 1.27ms for glitch-free audio processing; the ESS chip precisely captures subtle sonic details including vocal breath noises and instrumental harmonics, achieving ultra-low THD of 0.0048% on music input for clean, transparent and uncluttered sound. All output channels are fitted with DEL dual-engine limiters to automatically suppress overloaded signals, eliminating piercing howling and preventing speaker burnout caused by overload.

The unit connects to control software via USB, Wi-Fi or wired LAN. Built-in RTA real-time acoustic analyzer helps sound engineers tune ideal sound quickly, with switchable Chinese/English UI. It enables consistent premium sound performance whether for single-room installation or batch deployment across chain KTV brands.
