Additional Information

o Whereas with conventk)nal Dolby Pro Logic the surreund

channel playback frequency band was limited, Dolby Pro Logic

]i effers a wider band range (20 Hz to 20 kHz or greater). In

additien, the surround channels were monaural (the surreund

left and right channels were the same) with previeus Dolby Pro

Legic, but with Delby Pro Logic ]i they are played as stereo

signals.

• Various parameters can be set according to the type of source

and the contents, se it is pessible te achieve optimum deceding

(_ page 56).

Dolby Pro Logic lix

Delby Pre Logic ]Ix furthers tile matrix decoding technelogy of

Delby Pro Logic ]I to decode audio signals recorded on two

channels into up te 7.1 playback channels, including the surreund

back channel. Delby Pre Logic ]Ix also allews 5.1-channel

sources te be played in up to 7.1 channels.

The mode can be selected according to the source. The Music

mode is best suited for playing music, the Cinema mode for

playing movies, and the Game mode for playing games. The

Game mede can only be used with 2-channel audie sources.

•_ Sources recorded in Dolby Surround

• These are seurces in which three or more channels of surreund

have been recerded as twe channels of signals using Delby

Surround encoding technolegy.

• Delby Surreund is used for the sound tracks ef movies recerded

on DVDs, LDs and video cassette tapes, as well as fer stereo

broadcast signals frem FM radio, TV, satellite breadcasts and

cable TV.

• Decoding these signals with Dolby Pre Logic ]i makes it

pessible to achieve multi-channel surround playback. The

signals can alse be played en erdinary stereo equipment, in

which case they previde normal stereo seund.

• There are two types of DVD Dolby surround recording signals.

_,1,2-channel PCM stereo signals

rzh 2-channel Dolby Digital signals

• When either ef these signals is input to the AVR-786, the

surround mode is automatically set to Dolby Pro Legic ]i when

the DOLBY/DTS SURROUND mode is selected.

• Sources recorded in Dolby Surround are

indicated with the logo symbol shown below

[2] DTS Digital Surround

Digital Theater Surreund (also called simply DTS) is a multi-

channel digital signal format developed by Digital Theater

Systems.

DTS effers the same "5.1 " playback channels as Delby Digital

(front left, front right, center, surround left and surround right) as

well as the steree 2-channel mode. The signals for the different

channels are fully independent, eliminating the risk of

deterioration of seund quality due to interference between

signals, cresstalk, etc.

DTS features a relatively higher bit rate as compared to Dolby

Digital (1234 kbps for CDs and LDs, 1536 kbps fer DVDs) so it

operates with a relatively low cempressk)n 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 ef course no need for an extra disc;

the pictures and sound can be recorded simultaneeusly on the

same disc, so the discs can be handled in the same way as discs

with ether formats.

There are also music CDs recorded in DTS. These CDs include

5.1-channel surreund signals (compared to two channels on

current CDs). They do not include picture data, but they offer

surreund playback on CD players that are equipped with digital

outputs (PCM type digital output required).

DTS surround track playback effers the same intricate, grand

sound as in a movie theater, right in your ewn listening roem.

÷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 "hissing" noise from the CD

or LD player's analog outputs, if this neise is played with

the amplifier set at a very high volume, it may pessibly

cause damage te the speakers. To aveid this, be sure to

switch the input mode to "AUTO" or "DTS" before playing

CDs er LDs recorded in DTS. Also, never switch the input

mode te "ANALOG" or "PCM" during playback. The same

helds 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 se this preblem dees not occur.

÷2: The signals provided at the digital outputs of a CD or LD

player may underge some sort of internal signal processing

(output level adjustment, sampling frequency cenversion,

etc.). In this case the DTS-encoded signals may be

processed erroneously, in which case they cannot be

decoded by the AVR-786, or may only produce noise.

Befere playing DTS signals for the first time, turn down the

master velume to a low level, start playing the DTS disc,

then check whether the DTS indicator on the AVR-786

(_ page 23) lights before turning up the master volume.

÷ 3: A DVD player with DTS-compatible digital output is required

te play DTS DVDs. A DTS Digital Output lege is featured on

the front panel of cempatible DVD players. Recent DENON

DVD player models feature DTS-compatible digital eutput -

consult the player's owner's manual fer information en

configuring the digital eutput for DTS playback ef DTS-

encoded DVDs.
