high:
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 a decrease in the receiver volume setting to avoid potential
microphone/speaker feedback.
OptiVoice is a 3-position switch that automatically adjusts the sound quality of the primary
speaker’s voice. It allows teachers to shape the sound of their voice and helps to ensure maxium
speech clarity in low, medium and high noise levels.
low:
Use in low-noise situations and for most
natural voice quality.
medium:
Best setting for average classrooms
where low-medium noise levels are present.
