Harman Kardon CDR 20 Owners Manual - Page 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 20, be turned off and unplugged from their AC power source when any connections are made or a new component is installed. Locating the CDR 20 Since the CD transports in the CDR 20 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 20 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 20 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 20 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 20, 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 20, 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 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 processor. For best playback results, a digital connection is recommended, using the coaxial or optical ¢• outputs. Connect them to the matching digital 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 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 20'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 external processor, connect the CDR Coax-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 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 CDR Coax-In jacks §6 or CDR Optical In Jack ¶ 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 Coax In jacks §6 or CDR Optical In Jack ¶ on the CDR 20 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 FrontPanel Digital Input 6 on the CDR 20. Note that when both the front and rear panel digital inputs are connected to external sources, the CDR 20 will give priority to the front-panel input 6. 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 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 20 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 20, consult your dealer. 12 INSTALLATION AND CONNECTIONS
