Section 2 Operation (Continued)

2.2 Optional EnviroMic

The PR-216 may be equipped or retrofitted with the optional EnviroMic

feature for assistive listening applications where both environmental sounds

and the speaker’s voice from the transmitter must be heard.

This built-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 is used with a hearing aid and

optional 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.

Functions

M: Microphone on—for normal use
