The TM-10 conference table microphone adapter adds a whole new dimension to the versatile AT-216 personal assistive listening system. Simply inserting the clip-on lapel microphone included with the AT-216 into the TM-10 transforms the microphone into a table-top conference microphone, adding even more functionality to the system. Using the TM-10 allows the microphone to function as an acoustically tailored boundary-type microphone by using the reflective surface of a table or desk as the boundary area that the microphone picks up. This allows the user to hear everyone sitting around the table, eliminating the need to pass around a microphone. The TM-10 has been specially designed to maximize the high fidelity performance of the AT-216 personal assistive listening system by emphasizing the frequencies that enhance speech clarity.
