1.This product is a network audio processor, designed with domestic ARM chips, using the Linux operating system and high-performance FFT/IIR/FIR hardware acceleration functions for audio processing. The new generation FT-Designer integrated management platform, FionTu's various audio products, are freely configured in a modular manner, support online and remote management, and can be used through the FT-Deginer platform to monitor and control the system in real time. 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 2.Applicable occasions: sound reinforcement systems for small and medium-sized conference rooms or multi-functional halls, background music systems for churches and theaters, public broadcasting systems for large venues such as conference centers or hospitals
