SC-A204U UHF Wireless Conference With 4 Mic

The 4.3-inch TFT color display enables real-time monitoring of 8 channels, showing channel numbers, volume levels, operating frequencies, RF power, and audio waveforms. All settings can be easily adjusted via the responsive touch screen interface.
Featuring true diversity reception technology, the receiver’s intelligent CPU automatically selects the optimal antenna signal to ensure stable reception and prevent signal dropouts.
A display lock function prevents accidental adjustments—once activated, channel and volume settings remain fixed to avoid unintended changes during operation.
