School Applications for the
Active Noise Canceling Headphones
The NC500TFC Active Noise Canceling Headphone can be used
for creating the quietest of individual settings needed during
high stakes testing when being able to hear content and blocking
external noise is at a premium, or connected to an audio source for
optimal sound quality.
• When connecting the NC500TFC to an audio source for
use as a pair of headphones, plug one end of the cord into
the headphone and other into the audio source (CD or MP3 player,
computer or other multimedia player). When used this way, the
integrated CAL AUDIO™ system automatically enhances harmonics
in the audio signal to increase clarity and richness of the sound.
Note: The batteries do not need to be installed for the NC500TFC
to be used as a regular headphone. It will simply not have the active
noise cancellation functioning.
• To enable the active noise canceling system for additional
reduction of ambient noise, the power must be switched on.
• The active noise canceling system can work simultaneously
while using the headphone to listen to an audio source.
• Without power or a sound source, the headphone will act as
a passive ambient noise-reducing headphone.
