DTS Digital Surround

Digital Theater Surround (also called simply DTS) is a multi-channel digital signal format developed by Digital Theater Systems.

DTS offers the same “5.1” playback channels as Dolby Digital (front left, front right and center, surround left and surround right) as well as the stereo 2-channel mode. The signals for the different channels are fully independent, eliminating the risk of deterioration of sound quality due to interference between signals, crosstalk, etc.

DTS features a relatively higher bit rate as compared to Dolby Digital (1234 kbps for CDs and LDs, 1536 kbps for DVDs) so it operates with a relatively low compression rate. Because of this the amount of data is great, and when DTS playback is used in movie theaters, a separate CD- ROM synchronized with the film is played.

With LDs and DVDs, there is of course no need for an extra disc; the pictures and sound can be recorded simultaneously on the same disc, so the discs can be handled in the same way as discs with other formats.

Other media include CDs recorded in DTS. These are the same discs as conventional CDs (recorded in 2 channels) but include 5.1 channel surround signals. They do not include images, but they do permit surround playback on the ADV-M51 and on CD players.DTS surround track playback offers the same intricate, grand sound as in a movie theater, right in your own listening room.

2DTS compatible media and playback methods

The following are general examples. Also refer to the player’s operating instructions.

Media	DTS Digital output jacks		Playback method (reference page)
CD	Optical or coaxial digital output		Set the input mode to “AUTO” or “DTS” (page 44, 45).
	(same as for PCM)	2	Never set the mode to “ANALOG” or “PCM”.	1
LD (VDP)	Optical or coaxial digital output		Set the input mode to “AUTO” or “DTS” (page 44, 45).
	(same as for PCM)	2	Never set the mode to “ANALOG” or “PCM”.	1
DVD	Optical or coaxial digital output		Set the input mode to “AUTO” or “DTS” (page 44, 45).
	(same as for PCM)	3

1 DTS signals are recorded in the same way on CDs and LDs as PCM signals. Because of this, the un-decoded DTS signals are output as random “hissy” noise from the CD or LD player’s analog outputs. If this noise is played with the amplifier set at a very high volume, it may possibly cause damage to the speakers. To avoid this, be sure to switch the input mode to “AUTO” or “DTS” before playing CDs or LDs recorded in DTS. Also, never switch the input mode to “ANALOG” or “PCM” during playback. The same is true when playing CDs and LDs recorded in DTS on the ADV-M51 or on LD/DVD compatible players. With DVDs, the DTS signals are recorded with a special recording method so there is no problem. For DVDs, the DTS signals are recorded in a special way so this problem does not occur.

2 The signals provided at the digital outputs of a CD or LD player may undergo some sort of internal signal processing (output level adjustment, sampling frequency conversion, etc.). In this case the DTS-encoded signals may be processed erroneously, in which case they cannot be decoded by this unit, or may only produce noise. Before playing DTS signals for the first time, turn down the master volume to a low level, start playing the DTS disc, then check whether the DTS indicator on this unit (see page 45) lights before turning up the master volume.

3 To play in DTS Digital Surround on the ADV-M51, set “DVD SETUP” — “AUDIO SETUP” — “DIGITAL OUT” to “Normal” in the setup. (The factory default is “Normal”.)
