The Audio-Technica ATW-3211/831 3000 Series Wireless Lavalier Microphone System is a professional wireless audio solution designed for clear and reliable vocal capture. This system facilitates high-quality sound transmission for presenters and performers by integrating advanced wireless components with a high-performance microphone.
The ATW-3211/831 system includes three primary hardware elements that ensure seamless audio operation:
The AT831cH microphone utilizes a cardioid polar pattern to focus on the primary sound source. This directional pickup pattern reduces the capture of unwanted ambient noise from the sides and rear, improving overall sound isolation. As a condenser microphone, it provides the sensitivity required for accurate vocal reproduction in various professional settings.
As part of the 3000 Series, the Audio-Technica ATW-3211/831 ensures consistent signal integrity. The combination of the ATW-R3210 receiver and the ATW-T3201 body-pack transmitter provides users with the flexibility to move freely without sacrificing audio quality. This system supports professional applications where clear communication and hardware reliability are essential.
