[] ADDITIONAL INFORMATION

There are currently various types of multi-channel signals (signals or formats with more than two channels)

• Types of multi-channel signals

Dolby Digital (EX), Dolby Pro Logic, DTS (ES), high definition 3-1 signals (Japan MUSE Hi=Vision audio), DVD-Audio, SACD (Super Audio CD),

MPEG multi=channel audio, etc.

"Source" here does not refer to the type of signal (format) but the recorded content. Sources can be divided into two major categones

2 Types of sources

• Movie audio

Signals created to be played in movie theaters. In general sound is recorded to be played in movie theaters equipped

with multiple surround speakers, regardless of the format (Dolby Digital, DTS, etc).

In this case it is important to achieve the same sense of

expansion as in a movie theater with the surround channels.

To do so, in some cases the number of surround speakers is

increased (to four or eight) or speakers with bipolar or dipolar

properties are used

SL: Surround Lchannel

SR: Surround R channel

SB: Surround B (back) channel

Multiple surround speakers

• Other types of audio These signals are designed to recreate a 360 ° sound field using three to five speakers.

In this case the speakers should surround the listener from all sides to create a uniform sound

field from 360 °. Ideally the surround speakers should function as "point" sound sources in the

same way as the front speakers

SL SR

These two types of sources thus have different properties, and different speaker settings, particularly for the surround speakers, are required

in order to achieve the ideal sound.
