Using the Remote Controller

To use the remote controller, point it at the DX-7555’s
remote control sensor, as shown.

Remote control sensor

Notes:

• The remote controller may not work reliably if the
DX-7555 is subjected to bright light, such as direct
sunlight or inverter-type fluorescent lights. Keep this
in mind when installing the DX-7555.

• If another remote controller of the same type is used
in the same room, or the DX-7555 is installed close to
equipment that uses infrared rays, the remote control­ler may not work reliably.

• Don’t put anything, such as a book, on the remote con­troller, because the buttons may be pressed inadvert­ently, thereby draining the batteries.

• The remote controller may not work reliably if the
DX-7555 is installed in a rack behind colored glass
doors. Keep this in mind when installing the
DX-7555.

• The remote controller will not work if there’s an
obstacle between it and the DX-7555’s remote con­trol sensor.

DX-7555

Approx. 16 ft.
(5 m)

Notes:

• If the remote controller doesn’t work reliably, try
replacing the batteries.

• Don’t mix new and old batteries or different types of
batteries.

• If you intend not to use the remote controller for a long
time, remove the batteries to prevent damage from
leakage or corrosion.

• Flat batteries should be removed as soon as possible to
prevent damage from leakage or corrosion.

9

Connecting the DX-7555

Audio Connections

• Read the manuals supplied with your other audio
equipment.

• Don’t connect the power cord until you’ve completed
all audio connections.

ANALOG AUDIO OUTPUT

If your hi-fi amp or AV receiver doesn’t have a digital
input, use the supplied RCA/phono audio connecting
cable to connect the DX-7555’s ANALOG AUDIO
OUTPUTs to your amp’s analog CD inputs.

Notes:

• RCA/phono audio cables are usually color coded: red
and white. Use red plugs to connect right-channel
inputs and outputs, and use white plugs to connect
left-channel inputs and outputs.

• Push each plug in all the way to
make a good connection (loose
connections can cause noise or
malfunctions).

Right!

Wrong!

• To prevent interference, keep audio cables away from
power cords and speaker cables.

DIGITAL AUDIO OUTPUT

If your CD-R, MiniDisc, or DAT recorder has a digital
input, use a commercially available coaxial or optical
fiber digital audio cable to connect the DX-7555’s
COAXIAL or OPTICAL DIGITAL AUDIO OUTPUT
to your recorder.
You can also use the digital outputs to connect to an amp
that has a digital input.

Note:

The OPTICAL DIGITAL AUDIO
OUTPUT has a dust cap for keeping
out dust and dirt when it’s not in
use. Remove the cap before con­necting an optical fiber cable. Push
the plug in all the way to make a
good connection. Keep the dust cap
in a safe place for future use.

Connecting the DX-7555—Continued

Connections

With (Remote Interactive) you can control the
DX-7555 together with your other -compatible
Onkyo AV components. With some Onkyo AV receivers
you can use one remote controller to control all your
Onkyo components and use the following special
functions:

■ Auto Power On

If your DX-7555 is connected to an -compatible
Onkyo hi-fi amp or AV receiver, when you turn on the
DX-7555, the AV receiver will turn on and select the
DX-7555 as the input source.

■ Direct Change

If your DX-7555 is connected to an -compatible
Onkyo hi-fi amp or AV receiver, when you start playback
on the DX-7555, the AV receiver will select the
DX-7555 as the input source.

■ Dimmer

When you dim the display brightness on an -compat­ible Onkyo AV component, the displays on all other AV
components connected via are dimmed as well.

To use the functions, you need to connect one of the
DX-7555’s connectors to an connector on
another AV component in your system by using the sup­plied cable.
See the manuals supplied with your other -compati­ble AV components for more information.

Notes:

• Use only cables for connections.

• To use you must make an analog RCA/phono

connection between your DX-7555 and Onkyo AV
receiver even if they are connected digitally.

• The DX-7555 has two connectors. You can con-
nect either one to your Onkyo hi-fi amp or AV
receiver. The other connector is for connecting addi­tional -compatible components.

• Connect the DX-7555’s connector to only Onkyo
AV components. Connecting to other manufacturer’s
AV components may cause them to malfunction.

• Some Onkyo -compatible AV components may
not support the special functions described here.

To use you must make an analog audio connection (RCA/phono)
between the DX-7555 and your other Onkyo equipment even if they are
connected digitally.

About CDs

Handling CDs

• Carefully lift the disc from
its case, making sure to
hold it by its edges or cen­ter hole.

• You can use a soft, dry
cloth to wipe dust and finger-
prints off the surface of CDs.
Do not use volatile agents,
such as thinner or benzene.
Don’t use vinyl record clean­ers or antistatic agents.

Notes:

• Don’t keep a CD in direct sunlight or in locations
subject to high humidity or low temperature.

• Don’t leave a CD in the unit for a long period of time.

Supported Discs

The DX-7555 supports the following discs.

Disc Logo Format or file type

Audio CD

CD-R

CD-RW

CD Extra

• Some audio CDs use copy protection that doesn’t con­form to the official CD standard. Since these are non­standard discs, they may not play properly in the
DX-7555.

• The DX-7555 supports CD-R and CD-RW discs.
However, some CD-R and CD-RW discs may not
work properly for any of the following reasons: disc
burner characteristics, disc characteristics, the disc is
damaged or dirty. See the manual supplied with your
disc burner for more information. Condensation or
dirt on the optical pickup lens can also affect play­back.

• The DX-7555 supports 8 cm and 12 cm discs.

PCM

Audio CD, MP3

• If you load any other non-supported discs for reading
or playback purpose, they may cause noise or not
operate normally.

• The DX-7555 does not support disc types not listed.

• Don’t use discs with an unusual shape, such as those

shown below, because you may damage the DX-7555.

• Don’t use discs that have residue from adhesive tape,
rental discs with peeling labels, or discs with custom­made labels or stickers. Doing so may damage the
DX-7555 and you may not be able to remove the disc
properly.

Discs Made on Personal Computers

Discs made on personal computers, including those of a
compatible format, may not work properly in the
DX-7555 because of incorrect settings in the disc burn­ing software. Check the manuals supplied with your disc
burning software for additional compatibility informa­tion.

MP3 Compatibility

• MP3 discs must be ISO 9660 Level 1 or Level 2,
Romeo or Joliet compliant. Supported formats:
Mode 1, Mode 2 XA Form 1.

• Folders can be up to eight levels deep.

• MP3 files must be MPEG-1/MPEG-2 Audio Layer 3

format with a sampling rate of between 8 kHz and 48
kHz and a bit-rate of between 8 kbps and 320 kbps
(128 kbps recommended). Incompatible files cannot
be played.

• Constant bit rate MP3 files are recommended, how­ever, variable bit rate (VBR) MP3 files between
8 kbps and 320 kbps are supported. (Playing times
may display incorrectly.)

• MP3 files must have a “.mp3” or “.MP3” file name
extension. MP3 files without the proper extension will
not be recognized. To prevent noise and malfunction,
do not use these extensions for other types of files.

• The DX-7555 supports up to 499 total tracks includ­ing the folders of a disc and the MP3 files, however,
the maximum number of folders may not exceed 99.
Files and folders in excess of this cannot be played.
Note that if the file and folder structure is very compli­cated, the DX-7555 may not be able to read or play all
of the MP3 files on the disc.

• Disc, file and folder names may contain up to 32 char­acters.

• The maximum time that can be displayed for a single
track is 99 minutes and 59 seconds.

• The remaining time cannot be displayed when playing
MP3 files.

23

About CDs—Continued

• MP3 file and folder names (excluding the extension)
are shown on the display.

• The emphasis is not supported.

• Multisession discs are supported, however, some mul-

tisession discs may take a long time to load and some
may not load at all. When burning CDs we recom­mend that you use a single-session (disc-at-once), and
select “Disc Close.”

• Normally, the music in the audio session of a CD
Extra disc is played. However, you can set the
DX-7555 so that it plays any MP3 files in the data ses­sion of a CD-R/RW disc instead. If the data session
contains no MP3 tracks, the audio session will be
played regardless.

• The following ID3 tags are supported: versions 1.0/

1.1 and 2.2/2.3/2.4. Version 2.5 and later are not sup­ported. Normally, version 2.2/2.3/2.4 tags have prior­ity and will be displayed regardless of the ID3 VER 1
preference on page 21.

• For ID3 version 2 tags, information contained in the
beginning of the file are recognized. We recommend
that you include only title, artist name, and album
name information in ID3 tags. Compressed,
encrypted, and unsynchronized ID3 tags cannot be
displayed.

• Some MP3 files may have ID3 tags whose information
can be displayed no longer than 31 characters.

Notes:

• With CD-ROM, CD-R, and CD-RW discs that contain
many files and folders, and files other than MP3s, it
may take a long time to read the disc. We recommend
that you include only MP3 files on your discs, use
about 20 folders, and limit folder nesting to three lev­els deep.

• In this manual, MP3 files are referred to as tracks.

• Likewise, folders (directories) are referred to as
groups.

About Playing Copy-controlled CDs

Some copy-controlled CDs may not conform to the offi-
cial CD standard. These special discs may not play
properly on the DX-7555.
Don’t load discs that are not audio discs (e.g., CD­ROMs designed for use with computers), as these may
damage your speakers or amplifier.

24

■ Meaning of Displayed Messages

NO DISC:

No disc is loaded; otherwise disc reading has failed.

FULL:

An attempt was made to store more than 25 tracks in memory.

The DX-7555 contains a microcomputer for signal processing and control functions. In very rare
situations, severe interference, noise from an external source, or static electricity may cause it to
lockup. In the unlikely event that this should happen, unplug the power cord, wait at least 10
seconds, and then plug it again.

Onkyo is not responsible for damages (such as CD rental fees) due to unsuccessful recordings
caused by the unit’s malfunction. Before you record important data, make sure that the material
will be recorded correctly.
