Description
Audio-Technica ATW-3211N/AT831cH Wireless Lavalier Microphone System is a professional UHF wireless microphone system designed for presenters, lecturers, clergy, performers, corporate events, and broadcast applications. As part of the 3000 Series (4th generation), this system delivers reliable RF performance, clear speech reproduction, and intuitive operation for demanding environments.
The ATW-3211N/AT831cH system includes a true-diversity receiver, a rugged bodypack transmitter, and the AT831cH cardioid lavalier microphone. The receiver is housed in a durable half-rack metal chassis with removable antennas and a bright OLED display for real-time monitoring of frequency, RF signal strength, audio level, battery status, and system information. Automatic frequency scanning helps locate clean channels quickly, even in crowded RF environments.
The AT831cH lavalier microphone features a cardioid pickup pattern that provides focused voice capture while reducing ambient noise and feedback. This makes it suitable for hands-free speech applications such as presentations, conferences, theatre performances, and houses of worship. The compact design allows discreet placement while maintaining clear and natural vocal reproduction.
The bodypack transmitter offers selectable RF power output to optimize for range or battery life depending on the operating environment. A locking Hirose 4-pin cH-style connector ensures a secure connection to the lavalier microphone or other compatible accessories. The transmitter operates on two AA batteries, providing up to approximately 9.5 hours of operation.
True-diversity reception minimizes signal dropouts by continuously selecting the strongest signal from two antenna inputs. Users can also preset a backup frequency that can be activated instantly via the transmitter if interference occurs during operation.
Built for reliability, flexibility, and high-quality audio performance, the Audio-Technica ATW-3211N/AT831cH wireless lavalier system is an excellent solution for professional speech reinforcement and installed sound applications.
