Audio-Technica ATW-3255EG2EU Wireless In-Ear Monitoring EG2: 580.000 - 713.850 MHz

Professional Wireless In-Ear Monitoring with 3000 Series RF Stability

The Audio-Technica ATW-3255EG2EU brings studio-grade wireless monitoring to live stages. Built on the same UHF platform as the 3000 Series wireless microphone systems, this IEM package pairs the ATW-T3205 transmitter with the ATW-R3250 diversity bodypack receiver and ships with ATH-E40 in-ear monitors. The EG2 frequency version covers 580.000–713.850 MHz, giving engineers a wide tuning window for congested RF environments.

What Sets This IEM System Apart

Two features stand out. ATH-E40 in-ear headphones use Audio-Technica's proprietary dual-phase push-pull driver arrangement for tight low-end and clean transient response. The receiver also supports network monitoring via Audio-Technica Wireless Manager, letting engineers scan, assign, and deploy frequencies across every connected transmitter.

RF Performance and Tuning Range

RF stability is the foundation of any wireless IEM, with a 138 MHz UHF tuning bandwidth and antenna diversity on the receiver to keep the signal locked across a wide stage.

• Frequency Band: 580.000–713.850 MHz (EG2) — wide UHF window for clean frequency coordination
• Operating Range: 90 m — covers mid-size venues and outdoor stages
• Simultaneous Systems: up to 49 per venue — enough headroom for full band + crew mixes
• Channel Step — fine-grained 25 kHz tuning to avoid interference in congested RF environments

Audio Quality and Performer Controls

The bodypack gives the performer direct access to EQ, limiter, gain, balance, and personal mix controls, so each musician shapes their own monitor world without touching front-of-house.

• Frequency Response: 40 Hz–14.1 kHz — full-range audio for vocals, instruments, and click tracks
• Receiver Audio Modes — Stereo, Mix, Dual Mono, and Mono Balance routing for any monitor mix configuration
• Included IEM: ATH-E40 with dual-phase push-pull drivers — accurate, low-distortion in-ear sound

Charging, Battery Life, and Network Integration

The bodypack runs up to seven hours on NiMH and docks in the same chargers used by 3000 Series wireless mic transmitters.

• Battery Runtime: up to 7 hours on NiMH — covers a full headline set
• Charger Compatibility — ATW-CHG3 and ATW-CHG3N stations shared with 3000 Series mic transmitters
• Setup — IR SYNC plus RF scan frequency assignment for fast deployment without manual frequency lists
