Page: 13 / 90

Important Note:

To prevent possible damage

to your speakers or other components in your
audio system, we strongly recommend that ALL
system components, including the CDR 30, be
turned off and unplugged from their AC power
source when any connections are made or a
new component is installed.

Locating the CDR 30

Since the CD transports in the CDR 30 are pre-
cision instruments, they are subject to interfer-
ence from vibration. To minimize the possibility
of skipping during playback or recording, it is
recommended that the unit be placed on a
level, solid, vibration-free surface.

When installing the CDR 30 in a cabinet or
tight space, always make certain that there is
enough room in front of the unit for the disc
drawers to open fully, and that there is enough
space above the unit so that discs may easily
be inserted in the disc drawers.

In addition to the safety considerations outlined
on page 4, it is also recommended that the
CDR 30 not be placed in a location that is sub-
ject to direct sunlight or extreme heat or cold,
as these conditions may damage the discs used
in the player, or the player itself. Note that
audio amplifiers or high-power receivers, as
well as certain other electronic products, may
generate significant heat. For that reason, do
not place the CDR 30 directly on top of an
amplifier, receiver, or other heat source. Always
allow at least one inch of free space on all
sides of the CDR 30, as well as other electronic
products, to allow for proper ventilation.

The unit should also be kept away from sources
of water or damp conditions.

Connections to Your Audio System

When connecting the CDR 30, think of the
process as if your were connecting a standard
CD player and a tape or cassette recorder, with
the addition of the digital connections.

Play-Deck Connections

The rear panel connections labeled “CDP” refer
to the outputs of the

Play Deck

, which

functions as a standard CD player. Connect the
analog left/right

CDP Outputs

to the CD

inputs on your receiver, preamp or surround
processor. For best playback results, a digital
connection is recommended, using the

Coaxial

Optical

Outputs.

Connect them to

the matching digital inputs of your receiver, pre-
amp, processor or external digital decoder. Note
that you may have to change a setting on the
receiver or processor to link the digital input to
the “CD” button or input selector. Consult the
owner’s manual on that device for details, as
this configuration may vary from unit to unit.

Record-Deck Connections

The rear panel connections labeled “CDR” refer
to the inputs and outputs for the

Record Deck

. Depending on the capabilities of your

receiver, preamp or processor, you may find it
convenient to connect the analog inputs and
outputs to the jacks marked for a tape recorder.
As the CDR 30’s functions resemble those of
a standard tape recorder, this might make it
easier to select it as an input on your receiver
or preamp. Connect the analog

CDR-Out

Jacks

™

to the Play/In jacks of a Tape or Aux

input on your receiver or preamp. Connect the

CDR-In Jacks

to the Tape Rec/Out jacks on

your receiver or preamp.

To play the output of the Record Deck through
the digital decoder in your receiver or an exter-
nal processor, connect the

CDR Coaxial

∞

Optical

•

digital outputs jacks to the matching

digital-input jacks on your receiver or processor.
Note that you may have to change a setting on
the receiver or processor to link the digital
input to the “Tape” button or the specific input
selector associated with the digital inputs.
Consult the owner’s manual on your receiver or
processor for details, as this configuration may
vary from unit to unit.

To make recordings from external digital
sources, such as a CD, DVD or MD player, con-
nect the

CDR Coax-In Jacks

CDR

Optical-In Jacks

on the CDR to the

digital output jacks on your receiver or proces-
sor. If your receiver does not have digital-output
jacks, you may connect the

CDR Coax-In

Jacks

CDR Optical-In Jacks

on the CDR 30 directly to the digital outputs on
your CD player or other digital device.

Connections to a portable digital CD or MD
player may also be made by connecting the
Coax Digital Output of the player to the front
panel

Digital Input Jacks

on the

CDR 30. Note that when both the front and
rear panel digital inputs are connected to
external sources, the CDR 30 will give priority
to the front panel input. If it is impractical to
disconnect the front panel input when you need
to use the rear panel jack, simply turn off the
device connected to the front panel input. This
will stop the digital signal, and permit the rear
panel jack to be used.

IMPORTANT NOTES ON DIGITAL
CONNECTIONS:

Although digital-coax connections use the same
type of “RCA” phono jack as standard analog
signals, please take special care to connect digi-
tal signals only to digital jacks. In many cases,
the digital jacks may be identified by an
orange-colored insert ring around the center of
the jack. When making digital connections, be
sure to use coax-interconnect cables, such as
the one supplied with the CDR 30 or cables
intended for video applications. Even though
they have the correct type of RCA connector, do
not use audio-interconnect cables that have
twisted-pair construction, as they are not
appropriate for digital signal use. If you have
any questions about the type of cables to use
with the CDR 30, consult your dealer.
