Audio-Technica AT831CW

Overview

The Audio-Technica AT831CW is a mini cardioid condenser lavalier microphone designed to clip discreetly onto clothing or instruments, delivering clear and natural sound for performers and presenters. Its cardioid pickup pattern focuses on the sound source directly in front of the mic, reducing stage bleed and ambient noise, which allows for higher gain before feedback occurs. This microphone is highly sensitive and offers a wide frequency response, making voices sound full and instruments like acoustic guitars carry detailed tones effectively.

Key features

• Cardioid pickup pattern that isolates the desired sound source while minimizing background noise and feedback
• High sensitivity and broad frequency response for natural voice and instrument reproduction
• Factory-wired 4-pin Hirose connector for quick and secure connection to compatible Audio-Technica wireless bodypack transmitters
• Lightweight and low-profile design that remains comfortable for long periods of wear and allows freedom of movement on stage
• Flexible power options including external battery or phantom power support, suitable for various live sound and recording setups

Connectivity and compatibility

Ideal uses and environments

This lavalier mic is well suited for touring musicians who need a compact alternative to bulky instrument microphones, as well as for spoken-word events, corporate meetings, and worship services where an unobtrusive microphone is essential. Its ability to reject ambient noise and feedback makes it a strong choice for live sound engineers managing front-of-house audio in challenging acoustic spaces.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
