34 Connecting Your TV
Connecting a digital audio system
The TV’s Digital Audio Out terminal outputs a Dolby® Digital, DTS® or
2-channel down-mixed PCM (pulse-code modulation) signal for using
with an external Dolby® Digital and/or DTS® decoder, or other external
audio systems with optical audio input.
You will need an Optical audio cable. (Use an optical audio cable that
has the larger “TosLink™” connector and not the smaller “mini-optical”
connector.)

Before controlling the audio, see “Selecting the optical audio output
format” on page 111.
NOTE
Some audio systems may not be compatible with Dolby® Digital or DTS®
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.
❖The Dolby® Digital or DTS® format is available in the following
situations:
- When tuned to a digital RF channel
- When an HDMI® input is used
- When network devices are used
