If an audio signal is not input for 10 minutes
Infrared signal emission from the processor automatically stops when an audio signal
is not input for 10 minutes. The infrared signals are automatically emitted when an
audio signal is input again. The emission of the infrared signals may stop when an
extremely low sound is emitted for about 10 minutes during analogue input. If this
happens, raise the volume of the connected audio or video component and lower the
volume of the headphones. If signal noise is output from a component connected to
the LINE IN jacks, infrared signal emission may not stop.
Notes
• The brightness of the infrared emitter on the digital surround processor may vary. However,
this does not affect the transmission area.
• The headphones should be used within the infrared transmission area (see "Infrared
transmission area" on page 19).
• These open-air headphones are so designed that sound may also leak outside the headphones.
Be careful not to turn up the volume so high that it bothers people around you.
• The surround sound effect may not be obtained from sound sources that do not incorporate
video, such as music CDs.
• This system simulates the average HRTF
differ from person to person since the HRTF can vary between individuals.
