OPERATING INSTRUCTIONS - ENGLISH
Problem
No signal via the headphone.
Although a multi-channel
track is used, Headzone
Home only receives a
two-channel sound
("PCM Stereo" LED will
illuminate instead of "Dolby
Digital" or "DTS ® " LED.
Virtual "audio picture" is
"crooked".
The audio material sounds
distorted.
The virtual audio sources are
not found at the expected
positions.
Possible cause
• Wrong S/PDIF input
selected.
• The connected DVD/Blu-ray
player produces no signal at
the S/PDIF output (this can
happen if DTS
when the player does not
support DTS
• The connected player
produces a PCM signal with
a too high sampling rate
(e.g. 96 kHz audio track of
a DVD audio).
• Many DVD/Blu-ray players
® provide the option to
change over the output for-
mat at the S/PDIF output
between "PCM" and the
original data of the
DVD/Blu-ray audio track (bit
stream).
Regarding "PCM" a stereo
down mix is created out of
multi-channel formats.
• Bad receiving conditions
can rarely cause an
autonomous reset of the
head tracker to a new
"Front" position.
• The audio output levels are
set too high.
• The acoustical central axis
of the head tracker is not
found in the desired
position.
