The Audio-Technica 3000 Series Wireless In-Ear Monitor System delivers professional sound quality, durable design, and dependable RF performance, making it an excellent choice for houses of worship, live venues, and performing musicians. Designed with the same engineering principles as Audio-Technica's 3000 Series UHF Wireless Microphone Systems, it offers premium features at an accessible price point. The system includes a rackmount transmitter with front-panel OLED display and balanced XLR inputs, a body-pack receiver with antenna diversity and efficient headphone amp, and ATH-E40 professional in-ear monitor headphones with proprietary dual phase push-pull drivers for accurate, natural sound. The receiver supports stereo or mono operation, pan/personal mix control, EQ, limiter, and gain adjustments. With 138 MHz wideband UHF coverage (470"608 MHz, DF2 band), the system provides flexible frequency coordination and supports up to 49 channels per band. Engineers can manage setups using Audio-Technica Wireless Manager software, with features like cue mode for monitoring multiple channels and 3000 Link mode for compatibility with 3000 Series wireless mic components.
