2.2 Optional EnviroMic and Smart-Mic
The PR-216 may be equipped or may be retrofitted with the optional
EnviroMic or Smart-Mic feature for assistive listening applications where
both environmental sounds and the speaker’s voice from the transmitter
must be heard.
This built-in or plug-in omnidirectional environmental microphone has
been equalized to enhance speech discrimination when used with hearing
aids, headphones, or button transducers.
When the PR-216 with EnviroMic or Smart-Mic is used with a hearing aid
and neckloop or direct audio input cords, the hearing aid determines the
frequency response and sound pressure level (SPL) delivered to the ear
when the speaker uses the wireless microphone transmitter.
Note: The neckloop will only operate hearing aids having a “T” switch.
Direct audio input cord to the hearing aid may also be used if the hearing aid
has an audio input cord shoe with a level control. For best listening, a
hearing aid which can operate in the “T” position only is preferred when
using the PR-216 with the EnviroMic or Smart-Mic.
