Example of how to connect your equipment

For example, follow the steps below to assign OPTICAL to the

DVD device connected to the DIGITAL INPUT OPTICAL jack.

Here is explanation of how to connect the main components to the

TX-DS494 in the standard manner. There are many ways that any

one component can be connected, and it is up to you to decide

which method best fits your situation. The directions given here

are only one option and should only be thought of as such. It is best

to fully understand the nature of each connector and terminal as

well as each of your components and their features to ascertain

which method of connection is best.

1. Press the DVD Input Selector button.

The DVD input is selected and “DVD” appears in the display.

• Be sure to always refer to the instruction manual that came

with the component that you are connecting.

2. Press the DIGITAL INPUT button.

The current DVD setting (COAX 1) appears.

• Do not plug in the power cord until all connections have been

made.

• For input jacks, red connectors (marked R) are used for the

right channel, white connectors (marked L) are used for the

left channel, and yellow connectors (marked VIDEO) are used

for video connection.

3. Press the DIGITAL INPUT button repeatedly to

select “OPT”.

• Insert all plugs and connectors securely. Improper connections

can result in noise, poor performance, or damage to the

equipment.

Pressing the DIGITAL INPUT button repeatedly will change

the setting as follows:

For a detailed explanation of how to connect the devices given

below, refer to the pages listed.

Select if the input source is not from a

digital input jack.

Speakers: See page 17

Radio antenna: See page 18

About five seconds after “OPT” is selected, the original

display appears and the setting is completed.

If you have selected digital input, you can also select the input

signal format (refer to “Setting the input signal format” on

page 23).

Setting the digital inputs

When connecting digital source components to the DIGITAL

INPUT jacks on the rear panel, assign the input source button on

the front panel to either a DIGITAL INPUT OPTICAL or

COAXIAL jack depending on the type of connector on the digital

source components. The DVD, CD, VIDEO 1, VIDEO 2 and

TAPE inputs can be assigned to the DIGITAL INPUT jacks.

Note:

Do not assign a single DIGITAL INPUT jack to more than one

source.

For example, if you assign the OPTICAL jack to the DVD input,

since the OPTICAL jack is assigned to the CD input by the initial

setting, it would result in assigning a single OPTICAL jack to both

the CD and DVD inputs.

With the initial setting, the OPTICAL connector is assigned to the

CD input, COAXIAL 1 is assigned to the DVD input and

COAXIAL 2 is assigned to the VIDEO 1 input, and no input

connector is assigned to the VIDEO 2 and TAPE inputs.

Whenever you assign a DIGITAL INPUT jack to a different

source from the initial setting, be sure to change the initial setting

for the jack in advance.

Positioning speakers

This unit has two sets of speaker system terminals (for

SPEAKERS A and SPEAKERS B).

Speaker placement

Before connecting the speakers, place them correctly by

consulting the instruction manuals that came with them.

Ideal speaker placement varies depending on the size of your room

and the wall coverings. Here, only typical example of speaker

placement and recommendations are shown.

For surround playback, the configuration and placement of your

speakers are very important.

Important points regarding speaker placement

Front left and right speakers and center speaker

Standard speaker system for reproducing

surround sound

• Place these three speakers at the same height from the floor.

• Place each speaker so that sound is aimed at the location of the

listener’s ears at the listening position.

• Front right and left speakers

• Install the left and right front speakers at the same distance

from the listening position.

• Center speaker

Produces a rich sound image by serving as a sound source for

the front right and left speakers and enhancing the sonic

movement.

Surround left and right speakers

• Place these speakers so that their height is 1 meter (3.3 feet)

higher than that of the listener’s ears.

• Surround right and left speakers

Adds three-dimensional sonic movement and produces

environmental sound associated with the background and

effect sound for each scene.

Subwoofer

• The subwoofer can provide a similar sound effect regardless of

the installation position, provided that it is installed within the

room containing the listening position.

The FM indoor antenna is for indoor use only. During use, extend

the antenna and move it in various directions until the clearest

signal is received. Fix it with push pins or similar implements in

the position that will cause the least amount of distortion.

Either of the split ends of the AM antenna can be connected to

either terminal. Unlike speaker cabling, there is no polarity for

AM broadcast signals.

If the reception is not very clear with the attached FM indoor

antenna, the use of an outdoor antenna is recommended.

The AM loop antenna is for indoor use only. Set it in the direction

and position where you receive signals clearly. Put it as far away

as possible from the TX-DS494, televisions, speaker cables, and

power cords.

Assembling the AM loop antenna

When reception is not satisfactory with the attached AM loop

antenna alone, connection of an outdoor antenna is recommended.

1. Rotate the outer frame of

the antenna.

presence of a movie theater or concert hall in your room.

• If you play a CD or LD that supports DTS when the

“ANALOG” setting is selected on the TX-DS494, the DTS

encoded signal will not be decoded and noise will be output.

This noise could damage the amplifier and speakers.

Therefore, be sure to select “AUTO” and use the DIGITAL

INPUT jacks (OPTICAL/COAXIAL) to connect the DTS

source. (Refer to “Setting the input signal format” on page 23.)

Before using a surround mode, make sure the speaker setup has

been set (refer to page 21).

The configuration of the speakers are very important for the

surround sound. Refer to “Positioning speakers” on page 16 and

“Connecting speakers” on page 17.

• If you play a CD or LD that supports DTS when the “AUTO”

setting is selected, you may hear a noise for a short while until

the DTS decoder recognizes the DTS encoded signal and starts

operating. This is not a malfunction.

Surround modes

• If you press the pause or skip button on the player while

playing a DTS source, a short noise may be heard. This is not a

malfunction.

DOLBY DIGITAL Surround, DTS (Digital Theater

System) Surround

This 5.1-channel digital surround format enables you to individually

record and play five full-range (20 Hz-20 kHz) channels (left and

right front, center, two surround channels) plus an LFE channel

(Low Frequency Effect) for the low-range effect sound. It will create

a realistic sound that could be heard in the theaters and concert halls.

• The DTS indicator on the TX-DS494 lights up while it plays

the DTS source. When playback concludes and the DTS signal

transmission stops, the TX-DS494 remains in DTS mode and

the DTS indicator remains lit. This prevents noise when you

operate the pause or skip button on the player. Therefore, if the

source switches from the DTS signal to the PCM signal

immediately, the PCM signal may not be played. In this case,

stop the playback of the source on the player for about 3

seconds, then resume playback.

DOLBY DIGITAL: Select this option when you play a DVD

video that has a

or CD that has a mark.

mark.

• Some CD players and LD players may be unable to play DTS

sources correctly even if you connect the player to the

TX-DS494 digitally. This is because the digital signal has

been processed (such as the output level, sampling frequency,

frequency response, etc.), and the TX-DS494 cannot recognize

the signal as DTS data. Therefore, you may hear noise when

you play a DTS source while processing the signal.

DOLBY PRO LOGIC II surround

This is a 5-channel surround system of a new generation, casting a

bridge between the previous 4-channel (Left/Right Front, Center

and monaural surround channels) Pro Logic surround and 5.1-

channel Dolby Digital surround. Dolby Pro Logic II provides the

MOVIE mode optimized for viewing movies and the MUSIC

mode optimized for listening to music. In the MOVIE mode, the

surround channel, which has been monaural and based on narrow

band, is reproduced in stereo so that the feeling of movement in the

played movies is more enhanced. In the MUSIC mode, the

surround channel reproduces natural sound field even with 2-

channel music sources.

• The TAPE OUT or VIDEO 2 OUT jacks of the TX-DS494

output analog audio. Do not record CDs or LDs that support

DTS using these jacks. Otherwise, you will record a DTS

encoded signal as noise.

The MOVIE mode allows you to enjoy VHS and DVD software

carrying the

marking as well as some of TV broadcast

programs. The MUSIC mode allows you to enjoy stereo music

from CD, etc.

Analog/PCM (Pulse Code Modulation) surround

Analog sources include the audio records, AM/FM broadcasting

and cassette tapes. The PCM (Pulse Code Modulation) signal is a

kind of digital audio signal, which is recorded directly on CD or

DVD without being compressed. When an analog or PCM source

is played, you can enjoy unique surround modes to Onkyo as listed

below.

ORCHESTRA: This mode is suitable for classics and opera

music. The center channel is cut and the

surround channels are emphasized to widen the

stereo image. It will simulate

natural

reverberation that can be created in a large hall.

UNPLUGGED: This mode is suitable for acoustic instrumental

sounds, vocals, and jazz music. By

emphasizing the front stereo image, it will

simulate the acoustics in front of the stage.

ALL CH ST:

This mode is useful for background music. The

front and surround channels will create a stereo

image.
