Import Digital Audio Processor K-3000 Wifi On-Line — Buy in Bulk from Supplier in China

The Lannge Electronic Co., Ltd. Digital Audio Processor K-3000 Wifi On-line is a network-enabled audio management device designed for professional loudspeaker calibration and signal routing. It supports up to eight input channels and twelve output channels, with sample rates up to 96 kHz and 32-bit floating-point processing. The unit includes built-in WiFi for remote configuration via a web interface, eliminating the need for physical access during system tuning.

The processor runs on a proprietary DSP architecture with real-time FIR and IIR filtering, delay compensation, and dynamic range control. It accepts standard audio formats including WAV, FLAC, and AES3, and is compatible with common digital audio interfaces such as AES/EBU, XLR, and RCA. While the listing does not specify internal DAC or ADC resolution, typical pro-audio processors in this class use 24-bit or higher converters with THD+N below 0.005%. The firmware supports user-defined presets and allows for backup and restore via USB or network.

This unit is commonly used in live sound reinforcement, installed AV systems, and high-end home theaters where precise acoustic tuning is required. Buyers include audio integrators, rental companies, and commercial venue operators. Trade terms are not listed, but standard packaging includes a 19-inch rack-mountable chassis with power cable and Ethernet adapter.
