The TM-10 conference table microphone adapter adds a whole new dimension to the versatile AT-216 personal assistive listening system. Simply inserting the lapel microphone into the TM-10 transforms the microphone into a table-top conference microphone emphasizing the frequencies that enhance speech clarity.

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.

To use, remove the windscreen and tie-clip from the CM-183 lapel microphone and insert the microphone into the receptacle on the TM-10 adapter.
