Mute Function
The Mute Function is automatically activated so that sound output from the
headphones is cut off whenever the headphones are outside the infrared transmission
area, the infrared beams are interrupted, or the noise increases. The Mute Function is
automatically cancelled when you get closer to the digital surround processor or there
is no longer anything in the way of the infrared beams.
If an audio signal is not input for 10 minutes
Emission of the infrared beams from the infrared transmitter in the digital surround
processor automatically stops when an audio signal is not input for 10 minutes. The
infrared beams are automatically emitted when an audio signal is input again. In
some cases, the infrared beams from the infrared transmitter may stop when an
extremely low sound is emitted for about 10 minutes during analog input. If this
happens, raise the volume of the connected audio and video component and lower
the volume of the headphones.
Notes
• There may be differences in brightness of the infrared transmitter on the digital surround
processor. However, this does not affect the transmission area of the infrared beams.
• The headphones should be used within the infrared transmission area (see "Infrared
transmission area" on page 13).
• Do not use the digital surround processor in areas exposed to direct sunlight or strong light.
The sound may be cut off.
• These open-type headphones are designed so that the sound also flows outside the
headphones. Be careful not to turn up the volume so high that it bothers the people around
you.
• Use a suitable volume level so that you do not harm your hearing and to ensure that you can
still hear surrounding sounds.
• The surround sound effect may not be obtained for sound sources which do not incorporate
video, such as music CDs.
• This system simulates the HRTF
person to person since the HRTF can vary between individuals.
