Anleitung Zusammenfassung


S.A.F.E.® ®®® Protection Circuit (8b) Self-Annealing Fuse Equipped: Instead of blowing internal protection rail fuses in the event of a dead- short to either a loudspeaker or speaker cable leads, the GFA-7705/07 will enter into a self-protect SAFE SAFESAFESAFE mode. If the output of any channel of the amplifier becomes shorted the protection circuit will trip and the individual Thermal Protection LED for that channel will light. The Protection LED will blink approximately every 5 seconds as the circuit will attempt to reset; if the short has been corrected the amplifier will resume proper operation. If the short is still present the channel will cycle off again. The cycling of the protection circuit will continue until the short is corrected or the amplifier power is switched off. 8 WARNING Whenever connections to or from the GFA-7705/07 are being made, be certain that the AC On/Off Switch (5) of the amplifier is in the OFF position, the AC Power Cord (4) of the amplifier is disconnected from the AC wall outlet and that all associated components are turned off. Installation & Hookup Unpacking the GFA-7705/07 Before your new GFA-7705/07 left our factory, it was carefully inspected for physical imperfections and tested for all electrical parameters as a routine part of ADCOM’s systematic quality control. This, along with full operational and mechanical testing, should ensure a product flawless in both appearance and performance. After you have unpacked the GFA-7705/07 inspect it for physical damage. Save the shipping carton and all packing material as they are intended to reduce the possibility of transportation damage, should the amplifier ever need to be shipped again. In the unlikely event damage has occurred, notify your dealer immediately and request the name of the carrier so a written claim to cover shipping damages can be initiated. THE RIGHT TO A CLAIM AGAINST A PUBLIC 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 BY THE CARRIER. SAVE ALL PACKING MATERIALS UNTIL THE CLAIM HAS BEEN SETTLED. Placement of the GFA-7705/07 During normal home operation the internal heatsinks of the GFA-7705/07 may become warm. However, there are instances during high-level playback into low impedances when the heatsinks will become much warmer than usual. To ensure the amplifier’s long-term, trouble-free operation, it is necessary to provide adequate ventilation for the heatsinks. Therefore, the GFA-7705/07 should be kept away from external sources of heat such as radiators and hot-air ducts. The GFA-7705/07 should never be placed with other heat-producing components in a cabinet or enclosure lacking free air flow. The top and bottom panels of the amplifier’s chassis have been provided with vents to allow the necessary cooling of the internal components. It is imperative that these vents are not obstructed in any way. We recommend that you do not stack other components on top of the GFA-7705/07. Not only will heat generated by the amplifier affect the performance of equipment stacked on top of the GFA-7705/07, but the free flow of air through the ventilating slots in the amplifier may be partially obstructed. This is particularly important if your system includes low-impedance loudspeakers which are difficult to drive, or you will consistently demand high volume levels from the amplifier and speaker system. If you observe these recommendations, the GFA-7705/07 will perform reliably in any reasonable environment. You should also pay attention to such normal considerations as protection from excessive dust and moisture. Occasional vacuuming of accumulated dust on the chassis, panels and around the ventilating slots should be all that is required. The optimal performance of your new GFA-7705/07 will ultimately depend on the care with which you make the connections between the amplifier, preamplifier, surround sound decoder and the loudspeakers. All input and output signal connections should be made only with high quality, low capacitance, shielded cables following the recommendations in the Inputs and Outputs section of CONNECTING THE GFA-7705/07. Quick Connections For those of you who are in a hurry to hook up your amplifier into your system, we have included this quick-connection section. The wiring is straight forward and expeditious if you use the proper cables and follow this diagram exactly. If you have any difficulties or questions, please refer to the appropriate section of this manual for complete descriptions and instructions. 9 10 Connecting the GFA-7705/07 Remember, that the Left and Right designations are as you are sitting down in your listening/viewing area. On the rear panel, the inputs and outputs are grouped in 5 or 7 bracketed sets, one set for each channel. They are as follows: LB — Left Back (GFA-7707 only) LS — Left Surround LF — Left Front C — Center RF — Right Front RS — Right Surround RB — R...
