Additional Information
[2] DTS Digital Surround
DTS Digital 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.

Playback method
(reference page)
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 the AVR-4806,
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 the AVR-4806 ( page 53) 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.
