All warnings on the unit and in its operating instructions should be adhered to. All operating and use instructions should be followed. Do not use this unit near water. For example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool. The unit should be installed so that its location or position does not interfere with its proper ventilation. For example, it should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or placed in a built-in installation, such as bookcase or cabinet, that may impede the flow of air through its ventilation openings. The unit should be situated away from heat sources such as radiators, heat registers, stoves, or other devices (including amplifiers) that produce heat. The unit should be connected to a power supply outlet only of the voltage and frequency marked on its rear panel. The power supply cord should be routed so that it is not likely to be walked on or pinched, especially near the plug, convenience receptacles, or where the cord exits from the unit. Clean unit only as recommended in its instruction manual. The power supply cord of the unit should be unplugged from the wall outlet when it is to be unused for a long period of time. Care should be taken so that objects do not fall, and liquids are not spilled, into the enclosure through any openings. This unit should be serviced by qualified service personnel when: A. The power cord or the plug has been damaged; or B. Objects have fallen, or liquid has been spilled, into the unit; or C. The unit has been exposed to rain, or liquids of any kind; or D. The unit does not appear to operate normally, or exhibits a marked change in performance; or E. The device has been dropped, or the enclosure damaged. DO NOT ATTEMPT SERVICING OF THIS UNIT YOURSELF. REFER SERVICING TO QUALIFIED Manual 4 | ADCOM GFP-715 Owner's SERVICE PERSONNEL. CAUTION Any outdoor antenna must be located away from all power lines. If an outside antenna is connected to your tuner or tuner/preamplifier, be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 701984, provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes, and requirements for the grounding electrode. a. Use No.10 AWG (5.3 mm2) copper, No.8 AWG (8.4 mm2) aluminum, No.17 AWG (1.0 mm2) copper clad steel or bronze wire, or larger, as a ground wire. b. Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 46 feet (1.221.83 m) apart. c. Mount antenna discharge unit as close as possible to where lead-in enters house. d. Use jumper wire not smaller than No.6 AWG (13.3 mm2) copper, or the equivalent, when a separate antenna grounding electrode is used. See NEC Section 810-21 (j).

NOTE TO CATV SYSTEM INSTALLER This reminder is provided to call the CATV system installer's attention to Article 82022 of the National Electrical Code that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical. Introduction Congratulations on your decision to purchase the GFP-715 stereo preamplifier. Two channel audio is better than ever! The new DVD Audio and SACD formats can support a wider frequency spectrum (100kHz) and greater dynamic range (144dB) than conventional CD. The GPF715 is designed to capture all the fidelity that high resolution audio has to offer, with precision broadband components and an ultra low noise floor. Equipped with a processor loop, a tape loop and a phono stage, this new ADCOM preamp hasn't forgotten about your legacy components. Audition the GFP-715 paired with an ADCOM power amp and DVD player and rediscover the magic of two channel. To realize the full potential of your new stereo preamplifier, and before making any connections to it, please read these operating and installation instructions thoroughly. carton and all packing material as they are intended to reduce the possibility of transportation damage should the preamplifier 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. The optimal perfomance of your new GFP-715 will ultimately depend on the care with which you make the connections between the amplifier, preamplifier and loudspeakers. All input and output signal connections should be made only with high quality, low-loss, low capacitance cables. For recommendations of the type and quality of interconnections that are best for your applications, consult with your ADCOM retailer. Safety Information There are no user serviceable parts inside. Refer all servicing to qualified service personnel. The unit must be connected to a power supply only of the type and voltage specified on the rear panel. Connect the component to the power outlet only with the supplied power supply cable or an exact equivalent. Do not modify the supplied cable. Do not defeat grounding and/or polarization provisions. The cable should be connected to a 3-pin polarized wall outlet, matching the wide blade of the plug to the wide slot of the receptacle. Do not use extension cords. Do not route the power cord where it will be crushed, pinched, bent, exposed to heat, or damaged in any way. Pay particular attention to the power cord at the plug and where it exits the back of the unit. The power cord should be unplugged from the wall outlet if the unit is to be left unused for a long period of time. Immediately stop using the component and have it inspected and/or serviced by a qualified service agency if: · the power supply cord or plug has been damaged; · objects have fallen or liquid has been spilled into the unit; · the unit has been exposed to rain; · the unit shows signs of improper operation; or · the unit has been dropped or damaged in any way. Placing the GFP-715 Although the GFP-715 does not generate much heat, it is good practice to ensure the amplifier's long-term, trouble-free operation to provide adequate ventilation for the unit. Therefore, the GFP-715 should be kept away from external sources of heat such as radiators and hot-air ducts. We recommend that you exercise care whe ...
