Audio technica ATW-3255DF2
Audio-Technica's 3000 Series IEM system offers a professional wireless in-ear monitoring solution for musicians, technicians, and venues seeking a balance between cost, durability, and audio quality.
This system includes a rack-mount transmitter with an OLED display and front-panel controls, a portable bodypack receiver with an integrated headphone amplifier, and ATH-E40 in-ear monitors with dual-phase push-pull technology.
Highlights include:
Wide UHF tuning bandwidth (138 MHz) for greater frequency flexibility in dense RF environments.
Antenna diversity reception (with an audio cable serving as a secondary antenna) to ensure radio signal stability.
Network capabilities via Wireless Manager software to monitor, configure, and coordinate system frequencies.
CUE mode allows a sound engineer to monitor multiple IEM channels from a single receiver.
3000 Link mode ensures the monitoring system's compatibility with other 3000 Series wireless devices.
Onboard audio controls: equalization (bass/treble), limiter, gain, balance.
Ability to operate in stereo or mono mode with pan/mix control customized for each user.
Up to 7 hours of battery life for the receiver with NiMH batteries, charging via ATW-CHG3/CHG3N docks (sold separately).
In practical use, user tests report that the system is reliable, stable, with dropout-free transmissions, and provides excellent audio clarity for stage monitors.
