The Array 2S Microphone provides far-field speech recognition with the accuracy of a "close talking" microphone. The beamforming technology of the Array 2S offers superior quality and performance over a single element microphone.

• Beamforming technology eliminates background noise for clear, crisp sound transmission
• Far-field speech recognition with the accuracy of a close talking microphone
• Small and compact for mounting on a desktop computer monitor.
• Andrea Communications USB-SA required for use with Mac or any PC with a shared audio port.
