12 INSTALLATION AND CONNECTIONS

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 2, be
turned off and unplugged from their AC power
source when any connections are made or a
new component is installed.

Locating the CDR 2
Since the CD transports in the CDR 2 are preci-
sion instruments, they are subject to interference
from vibration. To minimize the possibility of
skipping during playback or recording, it is rec-
ommended that the unit be placed on a level,
solid, vibration-free surface.

When installing the CDR 2 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
2 not be placed in a location that is subject 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 ampli-
fiers or high-power receivers, as well as certain
other electronic products, may generate signifi-
cant heat. For that reason, do not place the CDR
2 directly on top of an amplifier, receiver, or
other heat source. Always allow at least 2 cm of
free space on all sides of the CDR 2, 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 2, think of the pro-
cess 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 3, which
functions as a standard CD player. Connect the
analog left/right CDP outputs ¡ to the CD

inputs on your receiver, preamp or surround pro-
cessor. When a digital connection is prefered,
use either the coaxial ¢ or optical ª outputs.
Connect them to the matching coax or optical
inputs of your receiver, preamp, 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 recei-
ver, preamp or processor, you may find it conve-
nient to connect the analog inputs and outputs
to the jacks marked for a tape recorder. As the
CDR 2’s functions resemble those of a standard
tape recorder, this might make it easier for your
select it as an input. 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 Coax-Out ∞
or CDR Optical-Out • 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 selec-
tor associated with the digital inputs. Consult
the owner’s manual on your receiver or proces-
sor for details, as this configuration may vary
from unit to unit.

To make recordings from external digital sour-
ces, such as a CD, DVD or MD player, connect
the CDR Coax-In § or CDR Optical-In ¶
jacks on the CDR to the digital output jacks on
your receiver or processor. If your receiver does
not have digital-output jacks, you may connect
the CDR Digital Inputs §¶ on the CDR 2
directly to the digital outputs on your CD player
or other digital device. If the CD player has BOTH
types of outputs, you may want to connect one
to the input of your receiver and the other
directly to the CDR 2.

Connections to a portable digital CD or MD pla-
yer may also be made by connecting the Coax
Digital Output of the player to the Front-Panel
Digital Input 6 on the CDR 2. Note that
when both digital inputs are connected, the CDR
2 will give priority to the Front-panel input
6. To activate the rear panel input the front
panel connection must be unplugged.

COAX CONNECTIONS: Although digital-coax
connections use the same type of “RCA” phono
jack as standard analog signals, please take spe-
cial care to connect digital 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-inter-
connect cables, such as the one supplied with
the CDR 2 or cables intended for video applica-
tions. 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 2, consult your dealer.

OPTICAL CONNECTIONS: There are a number
of different types of optical connections, so make
certain that you use only “TOS” type optical
cables with the CDR 2. To ensure proper connec-
tion of optical cables, fully insert them into the
jack until there is an audible click. This tells you
that the connector has been completely inserted.
Remember to save the plastic dust caps that
cover the optical jacks, and replace them when a
jack is not in use to prevent dust from entering
the connection point.
