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 ATW-2110B/P2 Wireless System comprises of ATW-R2100b receiver, ATW-T210b UniPak® body-pack transmitter, AT831cW miniature cardioid condenser lavalier microphone.

The ATW-R2100b 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 2000b 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.

Key Features:

  • 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
