Product Introduction：

As an upgraded version of the VK3, the Leimeng Technology VK3Pro Audio System Processor is a multi-functional audio system processor designed specifically for KTV audio systems. It features both vocal effect processing and speaker management functions, enhancing audio performance and flexibility—delivering better sound quality and more convenient operation. Aligning with customer and market demands, it innovatively integrates two operating modes into a single product: Standard Mode and "X5" Mode (the device can be directly controlled via X5 software). In Standard Mode, it offers up to 13-band output EQ and more types of filters for adjustment. When switched to "X5" Mode, it fully caters to users who are accustomed to the "X5" interface: not only does it reproduce the classic and familiar "X5" tone, but it also significantly reduces users’ learning costs and operational difficulty, earning wide recognition in the market.

As a member of the VK series, the VK3Pro Audio System Processor boasts excellent hardware and software design. Its powerful performance is driven by a high-performance DSP chip customized for professional audio processing, enabling it to easily handle higher-precision and more complex DSP computing scenarios. With 64-bit computing precision and a system latency of 1.27ms, it maintains high-fidelity and high-reproduction characteristics after audio data processing, while its latency has reached an industry-leading level.

In terms of sound performance, the VK3Pro Audio System Processor supports 7-band parametric EQ adjustment for music input and offers tone selection, allowing users to choose between professional tones or classic tones. It features multi-parameter adjustment for echo and reverb, as well as professional vocal effect processing. For microphones, it supports 15-band EQ adjustment, and it disrupts the conditions for howling through software frequency shifting (with 3 adjustable levels and a shutdown option). Additionally, it is equipped with a high-pass adjustment function and a 10-level noise gate. Combined with optimized DSP algorithms, it successfully reduces THD+N (Total Harmonic Distortion + Noise) to a low level—this means the details of the input audio signal can be presented accurately and richly, achieving higher reproduction of the input signal and a comprehensively upgraded user experience.

On the output side, each output channel of the VK3Pro Audio System Processor is equipped with a compressor-limiter (dual-engine compression-limiting), a mixer, an equalizer (13-band parametric EQ for main output, center output, subwoofer output, and rear output), and high-pass/low-pass filters, with multiple function parameters available for adjustment. Together with the user-friendly PC control software (supporting RS232, USB driver-free installation, Wi-Fi, or wired network connection) and the RTA (Real-Time Audio Analysis) function, users can not only easily control device parameters but also monitor the audio input/output signal levels and the working status of the compressor-limiter in real time—making sound tuning faster and more accurate!
