What is DTS?
Digital Theater Systems has developed a digital audio compression method
similar to Dolby Digital AC-3. DTS processed audio is not as compressed
as Dolby AC-3. Therefore it is said to have more surround detail (separa-
tion), envelopment and better bass because of less compression (losses).

What do I need to play the DTS surround format?
The DTS source can be a DVD movie or CD. The DTS decoder is com-
monly found in the receiver.

Will a 5.1 channel DTS CD play in my CD player?
Only digital noise will appear from the L/R analog outputs if not automati-
cally muted. There will be digital output from the coaxial and optical ports.
Either digital output can be fed to a DTS stand-alone decoder or a re-
ceiver with a DTS internal decoder. The DTS receiver will produce the six
channels (“5.1”) or be downmixed into two (front L/R) channels depend-
ing upon the user menu.

A DTS CD compresses the six channels of audio into the space originally
occupied by the two-channel uncompressed CD audio. In order for six
compressed channels to fit on a CD, the data rate must be equal to or
less than the rate of a normal uncompressed CD.
occupied by the two-channel uncompressed CD audio. In order for six
compressed channels to fit on a CD, the data rate must be equal to or
less than the rate of a normal uncompressed CD.
Data rate of an uncompressed CD per channel =
16 bits/sample x 44, 100 samples/second = 706 Kbytes/sec.
There are two channels so the rate is doubled. Therefore the data rate of
a normal stereo CD = 1,412kbit/sec.
a normal stereo CD = 1,412kbit/sec.
This is just about the same data rate as a DTS compressed CD. The DTS
data rate is 1,411kbits, so no analog sound will be output from a DTS CD.
For comparison, CD, DTS, and AC-3 data rates are shown:
