I Technical Specifications
UR480 Wireless Microphone Receiver
One-click switch to change the used transmitter. The central control unit can control the receiver, interference warning and frequency interruption analysis functions, serial port communication and local area network communication functions. The host display can set the host number and display synchronously with the transmitter. There are 2 RJ45 data networking interfaces and 2 transmitter switching buttons. Multiple hosts can switch the transmitter for networking.
