The Audio-Technica ATW-3211EE1 is a fourth-generation 3000 Series professional wireless microphone system designed for reliable audio transmission in demanding production environments. Featuring a rackmountable ATW-R3210 receiver and an ATW-T3201 bodypack transmitter, this system is suitable for presenters, lecturers, performers, houses of worship, theaters, educational facilities, and live music applications. Its wide UHF tuning bandwidth and true-diversity reception help maintain clear, dependable audio in environments where radio-frequency interference can be a concern.

The receiver offers up to 2,400 selectable frequencies in the EE1 band, automatic frequency scanning, and infrared synchronization for convenient setup. A dual-mode OLED display provides operating frequency, RF signal strength, audio modulation, transmitter battery status, and mute information. The receiver's rugged metal half-rack chassis includes removable BNC antennas, balanced XLR and unbalanced 1/4-inch audio outputs, Ethernet networking, and rackmount hardware for portable or permanent installations. A programmable backup frequency can also be configured for quick switching if interference occurs.

The included ATW-T3201 bodypack transmitter features a durable metal housing, a secure four-pin cH-style screw-down connector, an OLED display, adjustable input gain, and a tactile mute switch. It accepts compatible lavalier and headset microphones as well as suitable instrument or line-level sources. Selectable 10 mW and 30 mW RF output settings balance transmission strength and battery life, while two AA batteries provide up to 9 hours of operation with alkaline batteries or up to 9.5 hours with rechargeable NiMH batteries under the specified conditions. No microphone is included, allowing users to select a compatible microphone or instrument cable for their application.

Frequently Asked Questions

Does the ATW-3211EE1 include a microphone?

No. The system includes a bodypack transmitter but no microphone. A compatible lavalier or headset microphone, or suitable instrument cable, must be purchased separately.

What frequency band does the EE1 version use?

The EE1 band operates from 530.000 to 589.975 MHz. Frequency availability and permitted transmission power depend on local regulations.

What is the maximum operating range?

The specified range is up to 328 feet (100 m) in an open environment without interfering signals. Actual range depends on the installation and RF conditions.

Can the transmitter switch to a backup frequency?

Yes. A backup frequency can be configured in advance and assigned to the transmitter's programmable multifunction button.

Can the receiver be installed in a rack?

Yes. The half-rack receiver includes rackmount adapters for installation in a compatible 19-inch equipment rack.

Can multiple systems operate simultaneously?

The 3000 Series supports up to 40 simultaneous channels per frequency band, subject to regional availability and frequency coordination.
