Troubleshooting
Problem
Virtual audio sources seem to move while
turning your head
No spatial reproduction in surround
mode
Head tracker resets autonomously
Headtracker does not work properly
(small operating range or head tracker
"jumps around")
Hum when using analog inputs
When listening to a DVD, the low-
frequency range gets weaker when the
LFE channel is enabled in the Headzone
control panel
Headzone
®
is not working and
Headtracker LED is blinking red/off
When turning your Headzone
the settings are not the same as when
turning it off the last time.
Audio is played with a higher pitch than
it should be on Power PC MAC's
Possible Cause
Scale of the head tracker compensation
does not match your personal perception
"Full-range" tick box in the Headzone
software control panel is enabled and a
full-range signal is present on the LFE
channel
Bad link in the ultrasonic transmission
between DT 770 PRO HT or DT 880 PRO HT
and Headzone
®
Head tracker does not work properly
(small operating range or head tracker
"jumps around")
Reflections of the ultrasonic signal lead
to misinterpretation in the receiver
Ground loop
On some DVDs, the LFE channel is 180°
out-of-phase. Mixed with the L/R
®
channel, this leads to the observed
phenomenon

As told in this manual, Headzone
automatically stores all settings within
the hardware. In very seldom cases it can
happen that you turn off your
Headzone
®
device during the process of
storing or before new settings have been
stored.
When configuring your Headzone
vice to the lowest possible sampling rate
(32 kHz), your MAC will not properly
re-initialize this setting when you plug in
Headzone
®
the next time. Your MAC will
configure Headzone
possible sampling rate (96 kHz) instead,
while internally working with 32 kHz.
This problem is known as the "chipmunk
bug" on Power PC based MAC computers
and is not derived by Headzone
the native Apple Core Audio drivers. This
problem does not exist on Intel MACs
and will probably be solved with future
updates of MAC OSX.

Solution
Adjust the scale of the head tracker
compensation according to your needs
(see chapter 9.6.6 "Viewing and
customising the head tracker").

Disable the "full-range" tick box in the
Headzone
chapter 9.5.5 "LFE filtering" for details).
Check the positioning of the Headzone

Remove obstacles or change the
positioning of the Headzone
Try a different position for the

Try to run all involved devices from the
same power outlet to minimise the
physical measures of the ground loop.
Use isolating transformers at the analog
inputs.
Activate the LFE Phase Reverse tick box

update as described in chapter
9.9.3 "Updating the DSP".

When changing the Headzone
always wait about 3 seconds before
switching your hardware off. When you
discover your Headzone
up with all settings set to "0" you can
restore the factory preset by using the
default.hzo file in your installation folder
or do a factory reset as described at the
beginning of this chapter.
