UA-400 System Overview　
　　The UA Series microphones are designed for professional performance in stadiums, concert halls, houses of worship and other demanding audio environments. It scans for signal frequencies that could interfere with microphone transmissions and automatically determines the correct frequency for setup, minimizing error and increasing mic-to-mic sound continuity. The UA series receiver allows computer management and control. The software that comes with your UA series microphones can configure and log the transmission quality of up to 128 microphones, making later adjustments easier for sound engineers.
