The fuse is located inside the chassis and is not user-serviceable. If
power does not come on, contact your Onkyo authorized service station.
4. Care
From time to time you should wipe the front and rear panels and the
cabinet with a soft cloth. For heavier dirt, dampen a soft cloth in a
weak solution of mild detergent and water, wring it out dry, and
wipe off the dirt. Following this, dry immediately with a clean cloth.
Do not use rough material, thinners, alcohol or other chemical sol-
vents or cloths since these could damage the finish or remove the

Memory Preservation
This unit does not require memory preservation batteries. A
built-in memory power back-up system preserves the contents
of the memory during power failures and even when the unit is
unplugged. The unit must be plugged in order to charge the
back-up system.
The memory preservation period after the unit has been
unplugged varies depending on climate and placement of the
unit. On the average, memory contents are protected over a
period of a few weeks after the last time the unit has been
unplugged. This period is shorter when the unit is exposed to a
highly humid climate.

Positioning speakers
Positioning speakers
Speaker placement plays an important role in the reproduction of
Surround sound. The placement of the speakers varies depending
on the size of the room and the wall coverings used in the room.
The illustration shows an example of a layout for standard speaker
placement. Refer to this example when you position the speakers in
order to experience the best of Surround sound.

Sub-
Standard speaker placement
Center

For ideal Surround effects, all speakers should be installed. If a
center speaker or subwoofer is not connected, the sound from the
unused channel is properly distributed to the connected speakers in
order to produce the best Surround sound possible.
Front: The left, right, and center speakers should face the seated
listener and be placed at ear level. The center speaker produces a
richer sound image by enhancing the perception of the sound’s
source and movement.
Surround

speaker
Left
Surround: Place the left and right Surround speakers 1 meter
(3 feet) above the listener’s ear level and facing toward the sides of
the room, making sure that the listener is within the speakers’ dis-
persion angle. These speakers produce the feel of a moving sound
while creating the sensation of being in the middle of the action.
Subwoofer: Install a subwoofer with a built-in power amplifier for
powerful bass sounds. The placement of the subwoofer does not
affect the final quality of the sound image too much, so you can
install it with the room layout in mind.

This surround format consists of four channels (left and right front,
center, and monaural surround channels) and emphasizes the cen-
ter channel. This format is very effective for panning music, con-
versation, and three-dimensional sound movement output from
three front channels. It also simulates the atmosphere and surround
effects of the sound reflected from the side and rear walls of the
theater. Select this option when you play a VHS, VHS Hi-Fi, laser
DOLBY SURROUND
1. If you play a CD or LD that supports DTS when the “ANA-
LOG” setting is selected on the TX-DS484, 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 “DIGITAL” and use the digital input jacks (OPTICAL/
COAXIAL) to connect the DTS source. (Refer to “Switching
between digital and analog inputs” on page 19.)
disc, or DVD video that has a
mark.
2. If you play a CD or LD that supports DTS when the “DIGITAL”
setting is selected, you may hear a noise for a short while until the
DTS decoder recognizes the DTS encoded signal and starts oper-
ating. This is not a malfunction.
Onkyo’s Surround modes
The TX-DS484 offers the following special Onkyo Surround
modes for the sources other than Dolby Digital and DTS sounds.
3. If you press the PAUSE or SKIP button on the player while play-
ing a DTS source, a short noise may be heard. This is not a mal-
function.
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 a natural
reverberation that can be created in a large hall.
4. The DTS indicator on the TX-DS484 lights up while it plays the
DTS source. When playback concludes and the DTS signal trans-
mission stops, the TX-DS484 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 three seconds, then resume
playback.
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.
5CH STEREO: This mode is useful for background music.
The front and surround channels will create a stereo image.
STEREO
5. Some CD players and LD players may be unable to play DTS
sources correctly even if you connect the player to the TX-DS484
digitally. This is because the digital signal has been processed
(such as the output level, sampling frequency, frequency
response, etc.), and the TX-DS484 cannot recognize the signal as
DTS data. Therefore, you may hear noise when you play a DTS
source while processing the signal.
Select this mode when you do not wish to use the surround mode.
All input sound is output from the front speakers.
• A system with L/R front and center speakers
The following modes are available:
DOLBY 3STEREO
6. The Rec Out jacks of the TX-DS484 output analog audio. Do not
record CDs or LDs that support DTS using these jacks. Other-
wise, you will record a DTS encoded signal as noise.
The surround channel sound is output from the left and right
front speakers.

This is a normal stereo mode. Surround mode is cancelled.

Notes:
• The LFE Level Control function is effective only on the Dolby
Digital/DTS Surround sound.
• The degree of the low frequency effect is already programmed
into the source materials. Some materials may produce only
small or no effects.
Dolby Digital sound:
“0dB” is recommended. If the low range sounds too loud for your
taste, select –10dB or –∞dB.
DTS sound:
“+10dB” is recommended for cinema sound sources. If the low
range sounds too loud for your taste, select 0dB or –∞dB. “0dB” is
recommended for music sound source. If the low range sounds too
loud for your taste, select –∞dB.
Setting the input signal format
If the input source is DVD, CD, VIDEO 1, VIDEO 2, or TAPE, you can specify the input signal format. The default setting is “AUTO.” How-
ever, you can change this according to the signal format of the input source.
For example, follow the steps below to specify the input signal for-
mat for the DVD input:
AUTO (Auto Detect mode)
In this mode, the unit automatically detects the input signal format
(Dolby Digital, DTS, or PCM) and performs necessary decoding
process. If the digital signal is not being input, the unit will play the
signal input from the analog input jacks.
1. Press the DVD button.
DVD is selected as the input source and “DVD” appears on the
display.
2. Select the desired input signal format using the DVD button.
Pressing the DVD button repeatedly will change the format
option as follows:
DIGITAL (Digital Input Auto Detect mode)
In this mode, the unit automatically detects the input signal format
(Dolby Digital, DTS, or PCM) and performs necessary decoding
process.
AUTO
DIGITAL
ANALOG
ANALOG (Analog Audio Signal Process mode)
The unit plays the audio signal that is input from the device con-
nected to the analog input jacks.
Press the DVD button repeatedly to display the desired format.
After five seconds, the original display appears and the setting is
completed.
Note:
You need to assign digital input to DVD to specify the input sig-
nal format. (Refer to “Switching between digital and analog
inputs” on page 19 for more information.)
