    Audio-Technica ATW2129 Lavalier Wireless System Product Description

    Part of Audio-Technica's 2000 Series of UHF true-diversity wireless microphone systems, the ATW2129 wireless system is a 10-channel frequency-agile UHF wireless system designed to suit a variety of applications, including live performance, fixed installation, public address, A/V rental houses, and places of worship. It offers true diversity operation, easy setup, automatic frequency scanning with interference-free performance, and all the advantages of a high-quality, professional wireless system at an extremely affordable price.

    Automatic Frequency Scanning

    Operating in the 600 MHz frequency band (656.125-678.500 MHz, TV channels 45-48) with 10 selectable frequencies and true diversity UHF wireless technology, the 2000 Series features automatic frequency scanning. At the touch of a button, this function automatically determines and sets the best available frequency (open channel) -- particularly useful when employing multiple wireless systems, thereby avoiding interference and intermodulation.

    Use Up to 10 Simultaneous Microphones

    When there is a need to utilize multiple wireless systems simultaneously, any of the 2000 Series' 10 channels may be used together without any frequency coordination problems or group selection issues. Additionally, the 2000 Series incorporates Audio-Technica's digital Tone Lock squelch plus an easy-to-read LCD information display, which provides convenient visual indications of settings and operation status.

    System Includes:

    - AT829cW Cardioid Condenser Lavalier Microphone
    - ATW-T210 UHF UniPak Bodypack Transmitter
    - ATW-R2100 true-diversity receiver

    AT829cW Cardioid Condenser Lavalier Microphone

    This microphone's small size allows it to be worn as a lavalier, or hidden in loose clothing. For normal lavalier use, attach the microphone about 6 in. (15 cm) below the user's chin. Anticipate movements that may cause the microphone to rub against or be covered by clothing and position the microphone to avoid it.

    ATW-T210 UniPak Bodypack Transmitter

    The versatile ATW-T210 UniPak body-pack transmitter has a multi-function LCD display, soft-touch controls for convenient set-up and operation, along with low- and high-impedance inputs (with a bias connection) for use with dynamic and electret condenser microphones as well as Hi-Z instrument pickups. In addition to its programmable functions, the ATW-T210 has a hinged cover to limit access to controls as appropriate for the application and user. The ATW-T210 is powered by two easily installed 1.5V AA batteries that provide approximately nine hours of operation. The ATW-T210 is compatible with the Audio-Technica Wireless Essentials accessories.

    ATW-R2100 Wireless Receiver

    The true-diversity ATW-R2100 half-rack receiver features an all-metal housing for superb shielding, as well as dual independent receiver sections. Its true diversity operation selects the best signal from the two independent receiver sections, thus reducing dropouts and minimizing multipath distortion. The ATW-R2100 offers 10 PLL-synthesized UHF frequencies, advanced digital Tone Lock squelch, soft-touch controls with LCD information display, detachable UHF antennas, plus a rack-mount kit. Also included is a transmitter battery indicator LED, XLRM-type balanced and 1/4 in. unbalanced outputs, plus a ground-lift switch.

    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
