Here we describe a number of speaker settings for different purposes Use these examples as guides to set up

your system according to the type of speakers used and the main usage purpose

(1} Basic setting

Use this setting if your main purpose [s to listen to movie music and when using one set (two speakers) of

regular single-way or two way speakers as the surround speakers

F Fron_ speakers \

/ Momtor

As seen f:om above

• Set the front speakers with their front surfaces as

flush wgh the TV or monitor screen as possible

Set the center speaker between the front left and

right speakers and no further from the listening

position than the front speakers

• Consult the owner's manual for your subwoofer

for advice on placing the subwoofer within the

listening room

• If the surround speakers are direct-radiating

(monopohr) then place them slightly behind and at

an angle to the listening position and parallel to the

walls at a position 60 to 90 centimeters {2 to 3 feet)

above ear level at the prime listening position

seen f:om the side

(2} Using diffusion type speakers for the surround speakers

For the greatest sense of surround sound envelopment, diffuse radiation speakers such as bipolar types, or

dipolar types, provide a wider dispersion than is possible to obtain from a direct radiating speaker (monopohr)

Place these speakers at either side of the prime listening position, mounted above ear level

Pathof thesurroundsoun_lfromthe • Set the front speakers, center speaker and subwoofer

speakerstothe listeningposition in the same positions as in example 11)

• Set the surround speakers directly at the sides of

the listening position and 60 to 90 centimeters {2

to 3 feet) above ear level

• The signals from the surround channels reflect off

the walls as shown on the diagram at the left,

creating an enveloping and realistic surround sound

The AVRq 603 is equipped with a digital signal processing circuit that lets you play program sources in the surround

mode to achieve the same sense of presence as in a movie theater

Dolby Surround

(1) Dolby Digital (Dolby Surround AC-3)

Dolby Digital is the muki-channel digital signal format developed by Dolby Laboratories

Dolby Diggal consists of up to "51 " channels - front left, front right, center, surround left, surround right,

and an addgional channel exclusively reserved for additional deep bass sound effects {the Low Frequency

Effects - LFE - channel, also called the "1 " channel, containing bass frequencies of up to 120 Hz)

Unlike the analog Dolby Pro Logic format, Dolby Digital's main channels can all contain full range sound

information, from the lowest bass, up to the highest frequencies - 22 kHz The signals within each channel

are distinct from the others, allowing pinpoint sound imaging, and Dolby Digital offers tremendous dynamic

range from the most powerFul sound effects to the quietest, softest sounds, free from noise and distortion

of the LD player to the digital input iack

Please refer to the instruction manual of the adapter when making connection

2 Some DVD digital outputs have the function of switching the Dolby Digital signal output method between

"bit stream" and "{convert to) PCM" When playing in Dolby Digital surround on the AVRq 603, switch

the DVD player's output mode to "bit stream" In some cases players are equipped with both "bit stream

+ PCM" and "PCM only" digital outputs In this case connect the "bit stream + PCM" jacks to the AVR_

1603

(2} Dolby Pro Logic ff

• Dolby Pro Logic II is a new muki-channel playback format developed by Dolby Labolatories using feedback

logic steering technology and offering improvements over conventional Dolby Pro Logic circuits

• Dolby Pro Logic _] can be used to decode not only sources recorded in Dolby Surround (e) but also

regular stereo sources into five channels (front left, front right, center, surround left and surround right) to

achieve surround sound

• Whereas with conventional Dolby Pro Logic the surround channel playback frequency band was limited,

Dolby Pro Logic _] offers a wider band range (20 Hz to 20 kHz or greater) In addition, the surround

channels were monaural (the surround left and right channels were the same) with previous Dolby Pro

Logic, but Dolby Pro Logic _] they are played as stereo signals

• Various parameters can be set according to the type of source and the contents, so it is possible to

achieve optimum decoding (see page 18)

Sources recorded in Dolby Surround

These are sources in which three or more channels of surround have been recorded as two channels of

signals using Dolby Surround encoding technology

Dolby Surround is used for the sound tracks of movies recorded on DVDs, LDs and video cassettes to be

played on stereo VCRs, as well as for the stereo broadcast signals of FM radio, TV, satellite broadcasts

and cable TV

Decoding these signals with Dolby Pro Logic makes it possible to achieve multi-channel surround

playback The signals can also be played on ordinary stereo equipment, in which case they provide

normal stereo sound

There are two types of DVD Dolby surround recording signals

_ 2-channel PCM stereo signals

_2) 2-channel Dolby Digital signals

When either of these signals is input to the AVR-1603, the surround mode is automatically set to Dolby

Pro Logic II when the "DQLBY/DTS SURROUND" mode is selected
