Note

Depending on the device to be connected, you
might need to buy a different connector cord.
For further details, read the operating manual of
the device to be connected or ask your local
dealer.

To select a device connected to the
unit by the master unit

1Press (SOURCE) repeatedly until “CD” is

selected.

2Press (MODE) repeatedly until the device

you want to listen to is selected.
Example: Master unit display window

Tip

When you select a Sony BUS system­compatible device, it will automatically start
playing.

3 Start playing the device selected in 2.

For the playback method of the selected device,
refer to its operating manual.

4 Adjust the volume of the master unit and

selected device.

Notes

• Follow the steps below to play the audio file of
the computer connected to the USB jack of this
unit.
1 Press the MODE button of the master

unit to select “USB.”

2 Open the playback software (Windows

Media Player, etc.) on your computer.
3 Play the audio file (MP3,etc.).
After playing the audio file on the computer, if
you select “USB“ mode on the display of the
master unit, this unit may not recognize the
signal and sound may not come out.

• As the volume settings of each connected
device may differ, adjust the volume on each
device separately. As the sound output differs
on AUX IN 1 and AUX IN 2, connect the Sony
car audio DVD changer to AUX IN 1, and
connect a portable device (such as MD
WALKMAN, etc.) to AUX IN 2.

• While playing audio file in a device connected
to AUX IN 1, AUX IN 2, or the USB jack on this
