Note:
•
Some audio systems may not be compatible with Dolby
Digital bitstream signals. Older audio systems that are not
compatible with standard optical out signals may not work
properly, creating a high noise level that may damage
speakers or headphones. THIS DAMAGE IS NOT COVERED
BY YOUR WARRANTY.
•
The
DIGITAL AUDIO OUT
terminal may not output some
digital audio sources because of copy restrictions.
