Audio-Technica ATW-2129CI Wireless Lavalier Microphone System

Wireless Lavalier Microphone System for Clear Speech and Presentations

The Audio-Technica ATW-2129CI is a UHF wireless lavalier microphone system designed for presenters, performers, and production teams who need reliable wireless audio with consistent speech clarity. It pairs a true-diversity receiver with a UniPak bodypack transmitter and a compact lavalier microphone, making it well suited for presentations, houses of worship, live events, classrooms, and performance spaces. The system delivers dependable wireless performance while remaining accessible for both portable and installed setups.

True Diversity Receiver for Stable Wireless Performance

At the center of the system is the ATW-R2100c diversity receiver, which uses two independent receiver sections to continuously select the strongest signal. This approach helps reduce dropouts and radio-frequency interference in crowded wireless environments. Automatic frequency scanning simplifies setup by quickly identifying available channels, allowing users to deploy the system with minimal configuration.

Multiple Selectable Channels for Flexible System Expansion

The ATW-2129CI provides 10 user-switchable UHF channels, supporting multiple wireless systems operating at the same time. This makes it suitable for panel discussions, worship services, stage productions, and venues that require more than one microphone. Channel selection is straightforward, helping users coordinate systems efficiently.

Balanced and Unbalanced Outputs for Broad Compatibility

The receiver offers both balanced XLR and unbalanced 1/4-inch outputs, allowing seamless connection to mixers, audio interfaces, powered speakers, and installed sound systems. A bright backlit LCD display shows channel selection, audio level, RF signal strength, and system status, ensuring clear visibility even in low-light environments.

UniPak Bodypack Transmitter with Secure Lavalier Connection

The included ATW-T210c UniPak bodypack transmitter is lightweight and comfortable to wear for extended periods. It features a locking 4-pin cW-style connector that securely connects the included AT829cW lavalier microphone. The lavalier mic clips easily to clothing and delivers clear, natural speech reproduction with minimal visual distraction.

Tone Lock Squelch for Interference Control

Audio-Technica’s Tone Lock squelch system helps prevent interference by ensuring the receiver only opens when it detects the correct transmitter signal. This contributes to cleaner audio and stable performance, even in environments with competing wireless devices.

Durable Receiver Design with Installation Options

The metal half-rack receiver is built for daily professional use and includes rackmount hardware and detachable UHF antennas. A ground-lift switch helps reduce hum caused by ground loops, supporting clean integration into a wide range of sound systems.
