Welcome!
Thank you for purchasing the Sony CD
changer system. This unit lets you enjoy CD
sound with the changer.
The CDX-444RF is a compact disc changer
system comprised of the wired remote
commander, the relay box, and the CD
changer. The CD changer modulates the audio
signal into the RF (Radio Frequency) signal so
that it can be received by the existing FM tuner
of your car audio. Therefore you will be able to
enjoy CD play with your car audio even if it
has no input terminals for a compact disc
player.
•Compact and space saving CD changer for
vertical, horizontal, suspended, or inclined
installation in your car.
•Supplied wired remote enables you to
control the CD changer installed in the trunk
room of your car.
•Repeat play function for playing a track or a
disc repeatedly.
•Shuffle play function for playing tracks of
one disc or of all discs in random order.
•D-BASS function for dynamic bass boot.
