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.
There are also music CDs recorded in DTS. These CDs include 5.1-channel surround signals (compared to two channels on current CDs). They do
not include picture data, but they offer surround playback on CD players that are equipped with digital outputs (PCM type digital output required).
DTS surround track playback offers the same intricate, grand sound as in a movie theater, right in your own listening room.

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 holds true when playing
CDs or LDs on a DVD player or LD/DVD compatible player. 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 35) lights before turning up the master
volume.
3 A DVD player with DTS-compatible digital output is required to play DTS DVDs. A DTS Digital Output logo is featured on the front panel
of compatible DVD players. Recent DENON DVD player models feature DTS-compatible digital output – consult the player’s owner’s
manual for information on configuring the digital output for DTS playback of DTS-encoded DVDs.
