Description
  • This product is a network audio processor, designed with Cortex-A9 dual-core + FPGA + DSP architecture, using Linux operating system, built-in ADI's latest SHARC, 64-bit floating-point operations, and high-performance FFT/IIR/FIR hardware acceleration functions for audio processing. The new generation of FT-Designer integrated management platform, FionTu's various audio products, are freely configured in a modular manner, support online and remote management, and can monitor and control the system in real time through the FT-Deginer platform. The audio processing part adopts a modular design scheme, which can be designed freely and flexibly, and uses a software drag-and-drop interface to facilitate the operation of the tuner. In terms of network transmission, FionTu's self-designed F-LAN audio network transmission protocol is used to realize the transmission, monitoring, and management of network audio, and supports audio interconnection with Dante-AES67 and QLAN-AES67
