In the event of unexpected interference, the system's innovative design allows users to set and activate a backup frequency with a simple press of the multifunction button on the transmitter, ensuring uninterrupted audio transmission. The OLED screens on both the transmitter and receiver provide clear readouts of settings and alerts, enhancing user experience and control.

For added convenience, the transmitter includes charging terminals compatible with the ATW-CHG3 and networkable ATW-CHG3N smart charging docks (sold separately), enabling easy recharging of NiMH batteries. The system also features a ground-lift switch to eliminate potential hum caused by ground loops, and offers both balanced and unbalanced audio output options to accommodate various setup requirements.

With its combination of advanced features and robust construction, the Audio-Technica 3000 Series ATW-3211/831 4th Generation Wireless System stands out as a reliable and professional solution for those seeking superior wireless audio performance.
