low:
Recommended for use in low-noise situations and for most natural voice quality.
medium:
Recommended for everyday use. Best setting for average classrooms where low-
medium noise levels are present.
high:
Recommended for use in high noise levels. Helps to ensure top comprehension
during critical tasks such as test-taking or hearing impaired instruction.
NOTE:
With each increase in level, there is an increase of approximately 3dB in gain
(volume). This may require you to decrease your volume setting to avoid potential micro-
phone/speaker feedback.
OptiVoice is a 3-position switch that automati-
cally adjusts the sound quality of the primary
speaker’s voice. It allows teachers to shape the
sound of their voice and helps to ensure maxi-
um speech clarity in low, medium and high
noise levels.
