Before Using the DX-7555
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.
To use the remote controller, point it at the DX-7555’s
remote control sensor, as shown.
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 control-
ler may not work reliably.
•Don’t put anything, such as a book, on the remote con-
troller, because the buttons may be pressed inadvert-
ently, 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.

Connecting the DX-7555
•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-fiamp 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).
•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 con-
necting 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.

Onkyo hi-fiamp 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-fiamp orAV 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 -compat-
ible 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 sup-
plied cable.
See the manuals supplied with your other -compati-
ble 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-fiamp or AV
receiver. The other connector is for connecting addi-
tional -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.
