Product Description

The ATW2110a-E6i system consists of (1) ATW-R2100a receiver, (1) ATW-T210a UniPak® transmitter, and (1) Countryman E6i Omnidirectional Earset Mic.

Audio-Technica 2000 Series UHF Wireless Systems are the perfect introduction to professional grade wireless microphones. They are the most versatile systems in their price range. Features include 10 selectable channels across two UHF frequency bands, automatic frequency scanning to help avoid unwanted interference, an easy to read LCD display, and consistently dependable performance.

At the touch of a button, automatic frequency scanning determines and sets the best available frequency.  Any of the 10 channels within each frequency band may be used together without any frequency coordination problems or group selection issues. The 2000 Series incorporates Audio-Technica’s digital Tone Lock™ squelch to fight interference.

The Countryman E6i uses a tiny mic capsule mounted on an even tinier boom that is rugged, flexible, and incredibly lightweight. Silicon padding at the earpiece helps keep the boom comfortably in place, even with glasses or other head-worn accessories. The more-flexible boom on the E6i is very easy to adjust and perfect when one mic is shared among several people. Practically invisible to live or broadcast audiences, the E6i is incredibly comfortable for the wearer. It captures the closest source clearly with excellent rejection of wind, ambient noise, and feedback. And its industry-unique snap-on cable extends the equipment life many times over.

The changeable protective caps provide moisture resistance and let you shape the frequency response for different situations or to match other microphones. The Countryman E6i Omni Earset is a top choice for presenters, educators, worship leaders, pastors, broadcasters, and many other applications.

Additional System Features:
• Rugged metal half-rack receiver with soft-touch controls and LCD display featuring RF and AF metering
• Balanced XLR and unbalanced 1/4” output jacks enable use with a wide variety of audio gear
• Includes rack-mount kit and detachable UHF antennas
• Ground-lift switch helps eliminate audible hum caused by ground loops between the sound system and receiver

Select one of two frequency bands:
Band D: 655.500 MHz to 680.375 MHz (996 frequencies)
Band I: 482.000 MHz to 507.000 MHz (1001 frequencies)

Selecting the best frequency band for your area is easy!
1. Go to
2. Mark the selection labeled "2000 (version "a"- Band D/I)". 
3. Scroll down and enter your zip code in the box at the bottom. 
4. Click "Start Check".
The AT Frequency finder will show you the number of compatible channels available in your area.

Consumer Alert:
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at
