What is Dolby Surround AC-3?

·Dolby Surround AC-3 is a new-generation digital audio format for multi-channel surround audio. With this digital audio format,you can create a five full-range channel system called a “3/2” channel surround system (left, center, right, and two surround chann els), which is a developed version of the conventional “3/1” channel surround system” (left, center, right, and only one surround ch annel).

·Adding to its five full range channels, Dolby Surround AC-3 supports an LFE (low frequency effect) channel, which is used solye for low frequency sounds independent of the other channels. Dolby Surround AC-3 is sometimes referred to as a “5.1” channel format since this LFE channel is indicated as 0.1.

·This fully discrete 5.1 channel Dolby Surround AC-3 can reproduce sound of wide and dynamic range, changing your room into a home theater.

·Currently, LaserDisc is the only medium that employs the Dolby Surround AC-3 technology. In the near future, however, Dolby Surround AC-3 will be implemented in such media as DVD (Digital Video Disc), CATV (Cable Television), DBS (Direct Broadcast- ing), and HDTV (High Definition Television).
