manual abstract
In the event of physical damage, notify your ADCOM dealer immediately and request help in filing a written damage claim. THE RIGHT TO A CLAIM AGAINST A COMMON CARRIER CAN BE FORFEITED IF THE CARRIER IS NOT NOTIFIED PROMPTLY IN WRITING AND IF THE SHIPPING CARTON AND PACKING MATERIALS ARE NOT AVAILABLE FOR INSPECTION. SAVE ALL PACKING MATERIALS UNTIL THE CLAIM HAS BEEN SETTLED. The foam cocoon and carton were specifically designed to protect your GCA-510. Even though space is often at a premium in today's homes, we recommend that you save the packing materials in case you need to ship the unit anywhere in the future, 2) Select a stable, vibration-free location for the GCA-510 as close as possible to your other audio components. Make sure you have enough air space for proper ventilation. We recommend at least 3" of free air space above the GCA-510 and an inch to each side and to the rear of the unit. The GCA-510 is heavier than you might expect due to the high capacity toroidal transformer and large heat sink assembly. A stable supporting surface is necessary. We won't go into the endless and mostly unproved theories about extraneous vibrations and their deleterious effects on audio components except to say that the more massive and firmly anchored the supporting surface is, the less likely you’ll be to experience any problems. Proper airflow is important. Don’t block the ventilation slots on the bottom plate and top cover of the unit. The feet will insure enough air space below the GCA-510 for adequate circulation. WE RECOMMEND THAT YOU DO NOT STACK OTHER UNITS ON TOP OF THE GCA-510. 3) Turn off all the other components in your system. That means everything. And don't plug the GCA-510 into the AC outlet yet. Turning off system components before initial installation and connection avoids the nasty buzzes, thumps, and other sounds of electronic distress that occasionally accompanies hooking up components. 4) Connect the speakers to the 5~way binding posts (speaker outputs) of the GCA-510 ©& 0. The binding posts will accept a variety of connectors from bare wire to exotic audiophile “super banana” types. Make sure to observe proper polarity: Connect the GCA-510’s “+" (red) terminal for the left speaker to the “+" terminal on that speaker. Do the same for the terminals. Then repeat this for the right speaker. Exercise care in connecting your speakers. Be particularly alert that individual strands of speaker wire do not short between the “+" andterminals at either the amplifier or the speaker terminals. A note on speaker cable: We recommend the use of at least 16 gauge (AWG) two conductor “zip” cord for all speaker connections under 25' in length. For longer amplifier-to-speaker runs, we suggest 14 gauge "zip” cord. If you so desire, specialty wire specifically designed for high quality amplifier-speaker interface may be considered. Consult your ADCOM dealer for recommendations. 5) Connect the outputs of up to five (5) line level sources (CD player, tuner, etc.) to the appropriate inputs on the rear panel of the GCA-510 (O through ©). All Inputs are electrically identical. Remember to observe proper channel continuity — left channel output to left channel input and right to right. The RCA-type input jacks on ADCOM products adhere to the color convention of white for left channel and red for right. Most dual coaxial interconnect cables (or “patch “ cords) also follow this color coding or mark the cables in other obvious ways to make channel continuity easy to establish. A note on interconnects: We strongly recommend cables with low capacitance ratings. These will provide minimum interference for component-to-component signal transfer. If you desire, you may opt for specialty Interconnects specifically designed for low loss signal transfer. Consult you ADCOM dealer for recommendations. 6) The “Tape Out” connections © should be connected to the inputs of your system's tape or disc recorder. As long as you do not attempt to run a patch cord from either channel’s “Tape Out” to a digital recorder’s digital input, you should experience no problem. If you do attempt this feat, you will not be punished. Nothing will happen. Absolutely nothing. Eventually, you'll realize the mistake and correct it by connecting the GCA-510’s “Tape Out” jacks to the analog inputs of the digital recording device. Then you'll be able to record. The “Tape Out” jacks are buffered (or isolated) to preserve signal integrity under unusual load conditions. In other words, the GCA-510's sound quality will be unaffected by any conditions Inadvertently imposed by the recording device (low impedances, electrical short circuits, etc.) 7) (This Information applies only to certain versions of the GCA-510. Consult your dealer for details.) The GCA-51 0 is equipped with two rear panel convenience AC outlets; one switched © and one unswitched ©. Power to 4 the switched outlet is controlled by the front panel Power switch while the unsw...
