6.1 Connecting Audio System
Your Hydra HD supports AC-3 (Dolby Digital 5.1 channel). To enjoy multi-channel surround-sound, the
content source must carry multi-channel AC-3 signal. Please refer to your service provider for availability of
AC-3 5.1 programs.
You can enjoy multi-channel surround-sound such as 5.1 channel by connecting the Hydra HD to an
amplifier compatible with Dolby Digital. You can connect to your amplifier by either using the 75ohm digital
audio coaxial output or the digital optical audio output.

Consult your audio system user guide for connection. Take necessary precautions when working with
electric equipment. Remove the devices from wall power and be sure to use caution when moving
equipment to prevent injury.
If your connected TV or A/V equipment does not support AC-3, you can disable AC-3. You can enable or
disable AC-3 per decoder.
Enabling or disabling AC-3 is controlled by the IPTV middleware. For details of enabling and disabling AC-
3, please refer to usage instruction provided by your service operator.
Please refer to the following table for details of audio output used when AC-3 is enabled or disabled.
