Additional Information Optimum surround sound for different sources There are currently various types of multi-channel signals (signals or formats with more than two channels). 2 Types of multi-channel signals Dolby Digital (including Surround EX), DTS (including Surround ES), DVD-Audio, and Super Audio CD. Note on the above: MUSE 3.1 and MPEG multi-channel audio are not available to North American consumers - same is true for Dolby's AAC. "Source" here does not refer to the type of signal (format) but the recorded content. Sources can be divided into two major categories. 2 Types of sources • Movie audio: Signals created to be played in movie theaters.

combination of surround speakers being used and the
surrounding environment in order to achieve the ideal
surround sound for all sources. This means that you can
connect a pair of bipolar or dipolar surround speakers
