The Comtek AT-216 Wireless Auditory Assistance Kit with Plug-In Smart-Mic gives you a close-up on sound at work, home or on-the-go. 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 with smart-mic. This 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 the smart-mic. This input jack may also be used with other accessories such as handheld directional microphones
