Product Information

Audio Technica’s second generation of the well known 2000 Series now offers increased RF power on both the handheld and beltpack transmitters for increased link stability. Charging contacts on the transmitters allow easy operation with rechargeable batteries. The new ATW-R2100a receiver benefits from the latest Audio Technica 1/2 wave antenna technology (depends on the frequency range) to maximise range. The 12VDC bias voltage on both BNC antenna inputs allows operation with the ATW-B80 antenna booster or other active components. With this breakthrough series, Audio-Technica makes easy setup, automatic scanning and other advanced wireless features affordable as never before. Automatic frequency scanning – Standard on all 2000a Series wireless receivers – finds and sets the best available channel at the touch of a button. For those using multiple wireless systems simultaneously, the 2000a Series offers another ease-of-use feature: any of its 10 channels may be used together – eliminating confusing frequency groups and other frequency-coordinated problems.


Automatic frequency scanning finds an open channel at the touch of a button
Up to 10 user selectable channels are available. Compatibility varies from country to country
True Diversity operation selects the better signal from the two receiver sections, reducing dropouts
Tone Lock™ squelch function fights interference
Rugged metal half-rack receiver with soft-touch controls and LCD display featuring RF and AF metering
Ground-lift switch helps eliminate audible hum caused by ground loops between the sound system and receiver
ATW-T220a Handheld Microphone/Transmitter features a PRO41 capsule for maximum feedback rejection and consistent sound
