Surround Modes And Effects - Sony TAD-M30 Operating Instructions Manual

Surround Modes and Effects

The surround effects are determined by the audio encoding method of the software to be played.
These audio encoding methods are listed below.
Sony's original digital signal processing technology lets you enjoy epoch-making surround effects by creating virtual rear
speakers that do not actually exist or by producing sound that seems to come from farther back or even outside of the actual
rear speaker positions (Digital Cinema Sound).
Audio encoding Encoded audio and how it is heard
method
Dolby Digital Audio tracks are encoded separately for each of the front R/L (2ch), center (1ch),
5.1ch rear R/L (2ch) and sub woofer (0.1ch) channels for a total of 5.1ch. Therefore,
different sound is heard from each speaker.
If there are not enough speakers or if the existing speakers are unable to fully
reproduce the encoded audio, the audio for all channels can be played using only
the front speakers by not applying surround effects (Down-Mixing).
Dolby Surround
Audio tracks are encoded separately for each of the front R/L (2ch) channels.
(Dolby Digital 2ch or Audio encoded by this method can be decoded with surround effects by
Dolby Pro Logic) processing with Pro Logic to extract the center and rear sound components from
each channel.
Stereo (2ch) Audio tracks are encoded separately for the front R/L (2ch) channels. However,
this audio is not processed with Dolby Surround so surround effects are realized
by sound-field processing (adjusting the three elements of direct sound, early
reflections and reverberation).
Monaural (1ch) Only the front (1ch) audio is encoded.
Surround modes (sound fields) and effects
Mode Effect
AUTO Automatically identifies the audio signal encoding method and
DECODE decodes the signals in the manner which they are encoded.
For example, when you play a DVD encoded with only front
sound, the sound comes only from the front speakers.
NORMAL Decodes 5.1ch software in the manner which it is encoded.
SURROUND Automatically processes 2ch software using Pro Logic to create
surround effects.
ENHANCED Converts the surround channels to quasi-stereo (2ch) in order to
SUR(ROUND) add a sense of width when the rear sound is monaural (1ch) such
as Dolby Pro Logic.
