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

Systems¸

DTS offers the same "51 " playback channels as Dolby Digital {front left, front /jointfilesconvert/279709/bght and center, surround left and

surround right) as well as the stereo 2-channel mode¸ The signals for the d_fferent channels are fully independent,

eliminating the risk of deterioration of sound quality due to intederence between signals, erosstalk, 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-RQM 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 f-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 requged)

DTS surround track playback offers the same intdcate, grand sound as in a movie theater, right in your own listening

room¸

• DTS compatible media and playback methods

Marks indicating DTS compatibility: _ and

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 digita_ output Set the input mode to "AUTO" or "DTS" (page 16)

(same as fol PCM) _ 2 Never set the mode to 'ANALOG rror "PCM" _ /

Optical or coaxial digita_ output

DVD (same as fol PCM) @ 3 Set the i[iput mode to "AUTO" or "DTS" (page 16)

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 no_se 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" dubng 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 adiustment, sampling frequency conversion, etc} hi this case the DTS-encoded

signals may be processed erroneously, in which case they cannot be decoded by the AVR-1603, 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-1603 (see page 19)

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

If a problem should arise,first check the following.

1. Are the connections correct ?

2. Have you operated the receiver according to the Operating Instructions ?

3. Arethespeakers, turntableandothercomponentsoperatingproperty?

NOTE:

When 8 subwoofer has been connected and the virtual surround function is being used, the signal played from

the subwoofer channel is LFE only (only when playing Dolby Digital or DTS signals) for initial factory settings

(ie, the setting of the front speaker is "LARGE" and the setting of the subwoofer mode is "NORM"}

When subwoofer effects are felt to be weak, try setting the subwoofer mode to "+MAIN", or the front

speaker to "SMALL" in the System setup "Speaker Configuration" settings

Making these settings will result in the low-frequency sounds of the front channel being played from the

subwoofe[
