The Audio-Technica 3000 Series wireless in-ear monitor system was designed to bring professional sound quality and features to all levels of performers and performance venues. The 3000 Series wireless IEM provides an affordable, durable in-ear monitor system that is easy to use and, crucially, delivers high-quality sound with dependable RF.

With design elements modeled after the popular 3000 Series UHF wireless microphone systems, the 3000 Series IEM features a rack-mount transmitter with front-panel controls and large OLED display, body-pack receiver with an efficient headphone amp (it also conveniently charges in the same ATH-CHG3 and ATH-CHG3N charging stations as the 3000 Series UHF body-pack transmitters) and ATH-E40 professional in-ear monitor headphones with propriety dual-phase push-pull drivers. Together, these elements provide clear, natural sound quality on any stage.

The 3000 Series wireless IEM offers exceptional wide-band UHF coverage (138mHz), available in frequency band DF2 (470–608mHz), receiver antenna diversity to ensure RF stability and stereo or mono operation with pan/personal mix controls. Additional features include network monitoring and control via the Audio-Technica Wireless Manager software, a cue mode that allows an audio engineer to monitor several IEM channels from a single receiver, and a 3000 Link mode that enables compatibility with 3000 Series wireless microphone components.

Mixing and performing on a smaller scale shouldn’t have to mean sacrificing sound quality. Through the 3000 Series Wireless In-Ear monitor system, Audio-Technica continues to deliver on its promise of making high-quality audio accessible to all.
