Decoding with an external decoder or home theater
receiver
You can use an external decoder to process Dolby Digital, DTS, DTS-ES or
Dolby Digital EX signals from your Sound Blaster X-Fi device (such as Sound
Blaster X-Fi audio card, Digital I/O Module*, X-Fi I/O Drive* or X-Fi I/O
Console*) and output the content to 5.1 and 7.1 speakers.
Alternatively, you can use a home theater receiver to decode Dolby Digital or
DTS signals to 5.1 speakers.
For more information on external decoders or home theater receivers, the
associated speaker connection settings, or how to set up your DVD player
software to use the digital output, please consult the relevant User's Guide.
