Operation with Music only
When operating in an environment that does not require background sound input, you
can turn the mic off and use the volume knob to only amplify your music. The sound
should be cleaner and more solid than using a direct signal from your source.
The volume will also have a much higher level than from the source alone.
**Note - Do not turn the volume too high as the EAR3 does have the potential to
damage headphones and earphones should they not be rated for a higher audio input,
so use the volume amplification slowly with caution to avoid over boosting.
