12 INSTALLATION AND CONNECTIONS
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 26, be turned off and unplugged
from their AC power source when any connections are
made or a new component is installed.
Placement of the CDR 26
Since the CD transports in the CDR 26 are precision
instruments, they are subject to interference 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 26 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 26 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 amplifiers or high-power
receivers, as well as certain other electronic products,
may generate significant heat. For that reason, do not
place the CDR 26 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 26, 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 26, think of the process as
if you were connecting a standard tape or cassette
recorder, with the addition of the digital connections.
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 26’s functions resemble
those of a standard tape recorder, this may make it
easier to select it as an input on your receiver or pre-
amp. Connect the
Analog Output Jacks
¡
to the
Play/In jacks of a Tape or Aux input on your receiver
or preamp. Connect the
Analog Input Jacks
™
to
the Tape Rec/Out jacks on your receiver or preamp.
To play the output through the digital decoder in
your receiver or an external processor, connect the
Coaxial-Digital Output Jack
£
or the Optical-
Digital Output Jack
§
to the matching digital-input
jack on your receiver or processor. 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, connect the
Coaxial-
Digital Input Jacks
&
¢
or Optical-Digital Input
Jacks
^ ∞
on the CDR 26 to the digital output
jacks on your receiver or processor. If your receiver
does not have digital-output jacks, you may connect
the
Coaxial-Digital Input Jacks
&
¢
or Optical-
Digital Input Jacks
^ ∞
on the CDR 26 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 or Optical
Digital Output of the player to one of the front-panel
Digital Inputs
^&
on the CDR 26.
IMPORTANT NOTE 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 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-interconnect cables, such as the
one supplied with the CDR 26 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 26, consult your dealer.
