AST100, a stand-alone system for individual sites, is typically installed in meeting rooms along with one or more microphones and an automatic microphone mixer. Because the AST100 delivers robust acoustic echo and noise cancellation performance, it is often used instead of the video conferencing codec's microphone and acoustic echo canceller. It provides a single microphone or line level input, USB port (for external devices such as a PC). If additional microphone or line inputs are required, the  AST200 or AST800 models are recommended.

The AST100 features industry-leading acoustic echo cancellation technology, which prevents received audio from being retransmitted to its original location. The noise cancellation algorithms dramatically reduce ambient noise in the audio sent to other sites, without affecting speech quality. Automatic Gain Control (AGC) reacts only to valid speech patterns, bringing voices within desired levels.
