  • Introduction
  • Specification

The WEP5540 is a multi-network, multi-functional cloud broadcasting control host that integrates diverse control capabilities. When used with different upstream and downstream devices, it can form various application systems. It is mainly designed for 4G/5G/IP network transmission, wireless/wired co-cable transmission addressable systems, rural broadcasting village-wide sound projects, and small to large-scale broadcasting engineering systems. Powered by an ARM core and a DSP radio chip, the unit follows a design philosophy of diversified integration and optimized resource utilization. It incorporates functions such as emergency broadcasting, constant-voltage power amplification, monitoring, microphone interfaces, and power synchronization control, delivering a simple, practical, stable, and energy-efficient solution.
