Cpmtek AT216 FM System With Smart-Mic

At work, home, or on-the-go, the AT-216 gives you a close-up on sound. With internal audio processing that emphasizes the frequencies that define speech intelligibility, the AT-216 produces the highest fidelity available from any personal FM system. Incorporating unique options and accessories, it affords users the ability to effectively communicate in difficult listening environments. Not only are FM systems the best way to improve signal-to-noise ratios to overcome the listening challenges of distance, background noise, and reverberations, FM systems also significantly improve the effectiveness of hearing aids and cochlear processors. The NTC-102 neckloop provides a wireless connection to hearing aids 
and ear-level cochlear processors equipped with 
a telecoil (T-switch).

A unique environmental microphone feature adds even more functionality to the AT-216. It provides the listener with the ability to hear sounds from two sources: from the M-216 transmitter and from the PR-216 receiver’s environmental microphone. The receiver’s environmental microphone comes in one of two options:

Enviro-Mic: Combines environmental sounds from the receiver’s microphone with audio from the transmitter so that both sound sources are heard together.

Smart-Mic: Prioritizes the transmitter’s audio over environmental sounds from the receiver’s microphone. When no sound from the transmitter is present, the environmental microphone on the PR-216 receiver automatically activates. When sound from the transmitter is present, the receiver’s environmental microphone automatically mutes to help block out background noise.

The micro-mini jack on the PR-216 receiver uses the M-4020P plug-in environmental microphone for either the Enviro-Mic or Smart-Mic option. This input jack may also be used with other accessories such as handheld directional microphones and clip-on speech training microphones.

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.
