Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician. B WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm. Health & Safety Code Section 25249.6 - Proposition 65 - Service Precaution You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and should keep the safety during servicing by following the safety instructions described in this manual. C D E F 2 GM-7100M/XU/EW 1 2 3 4 5 6 7 8 [Important Check Points for Good Servicing] A In this manual, procedures that must be performed during repairs are marked with the below symbol. Please be sure to confirm and follow these procedures. 1. Product safety Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by following the safety instructions described in this manual. 1 Use specified parts for repair. Use genuine parts. Be sure to use important parts for safety. 2 Do not perform modifications without proper instructions. Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as radio/TV interference and foreign noise. B 3 Make sure the soldering of repaired locations is properly performed. When you solder while repairing, please be sure that there are no cold solder and other debris. Soldering should be finished with the proper quantity. (Refer to the example) 4 Make sure the screws are tightly fastened. Please be sure that all screws are fastened, and that there are no loose screws. 5 Make sure each connectors are correctly inserted. Please be sure that all connectors are inserted, and that there are no imperfect insertion. 6 Make sure the wiring cables are set to their original state. C Please replace the wiring and cables to the original state after repairs. In addition, be sure that there are no pinched wires, etc. 7 Make sure screws and soldering scraps do not remain inside the product. Please check that neither solder debris nor screws remain inside the product. 8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord. Damaged power cords may lead to fire accidents, so please be sure that there are no damages. If you find a damaged power cord, please exchange it with a suitable one. 9 There should be no spark traces or similar marks on the power plug. D When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary. 0 Safe environment should be secured during servicing. When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely. 2. Adjustments To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification. Adjustments should be performed in accordance with the procedures/instructions described in this manual. 3. Lubricants, Glues, and Replacement parts E Use grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied. 4. Cleaning For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances. 5. Shipping mode and Shipping screws To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment. Please be sure to follow this method especially if it is specified in this manual. 3 GM-7100M/XU/EW 5 6 F 7 8 1 A 2 3 4 CONTENTS SAFETY INFORMATION............................................2 1.

GENERAL INFORMATION 7.1 DIAGNOSIS 7.1.1 DISASSEMBLY A Removing the Case (Fig. 1) Case 1 Remove two black screws (M3 x 10). 2 Remove six white screws (M3 x 6). 3 Remove four black screws (M3 x 5). Caution) When you disassemble/re-assemble the Product with it placed upside down, take care not to damage the top surface. The Product uses several different types of screws. Take care not to confuse them during re-assembly. 2 2 2 3 3 B 1 1 3 2 2 2 3 C Fig. 1 Removing the Panel (Fig. 2) Panels are used for two sides individually, one for the RCA side and the other for the Power Terminal side. Panel for the RCA side 1 1 1 1 Panel for the RCA side 1 Remove six black screws (M3 x 8). 2 1 D 2 1 RCA Terminal (CN111) 2 Remove two black screws (M3 x 5). (They are used to secure the RCA Holder.) Panel for the Power Terminal side 3 Remove six black screws (M3 x 8). E Panel for the Power Terminal side 3 3 3 3 3 3 F Fig. 2 29 GM-7100M/XU/EW 5 6 7 8 1 2 3 Amp Unit Removing the Amp Unit (Fig. 3) A 4 Heat Sink 1 Remove six black screws (M3 x 10). 1 2 Remove six white screws (M3 x 12). 3 A Screw holes in the PCB are printed with numbers 1 to 12. 1 1 2 2 2 Remove screws in numerical order. Re-assembly takes the reverse order of disassembly. B Caution) The Amp Unit is adhered on the Heat Sink with silicon grease. This means forcibly removing the Amp Unit from the Heat Sink may break the PCB. 2 2 2 3 1 1 1 Remove all of twelve screws. Then, A 3 remove the two black screws (M3 x 5). Tighten screws whose length is M3 x 8 or more into the two screw holes so as to raise the Amp Unit above the Heat Sink. Then, remove the Amp Unit. (Since screw threads differ, 1 and 2 screws cannot be used.) C Fig. 3 Caution when re-assembling the Amp Unit and the Heat Sink Be aware that the RCA Terminal may break unless the Amp Unit and the Heat Sink are assem-bled following the correct procedures given below. D RCA Holder RCA Terminal (CN111) Amp Unit 1) Secure the RCA-side Panel on the Heat Sink with screws. (Fig. 2) 2) Place the Amp Unit on the Heat Sink aligning with two studs. (Fig. 4) 3) Move the Amp Unit until the RCA Holder on the Amp Unit comes in contact with the inside of the Panel. (Fig. 4) E Move the Amp Unit Caution in steps 2) and 3) When you place the Amp Unit on the Heat Sink, you will find no positioning marks to determine the direction of two panels. To position them correctly, the Amp Unit needs to be moved to the place where it comes in contact with the RCA-side panel. If you do not position them, an excessive force can be applied to the RCA Terminal. This may result in breakage. Heat Sink 4) Secure the RCA-side Panel and the RCA Holder with screws. (Fig. 2) 5) Secure the Amp Unit on the Heat Sink with screws. (Fig. 3) F Panel for the RCA side Stud Stud 6) Secure the Panel for the Power Terminal side in place with screws.

LPF (Low-Pass-Filter) Cut Off Frequency Control The power indicator lights when the power is switched on. D 3 3 You can select a bass boost level from 0, 6, 9 and 12 dB. For instruction of connecting the bass boost remote control to the amplifier, see the “Connection Diagram” section. Bass Boost Control 2 • When using with an RCA equipped car stereo (standard output of 500 mV), set to the NORMAL position. When using with an RCA equipped Pioneer car stereo with max. output of 4 V or more, adjust level to match the car stereo output level. • If you hear too much noise when using the speaker input terminals, turn the gain control counter-clockwise. If the sound level is too low, even when the volume of the car stereo used along with this power amplifier is turned up, turn gain control on the front of the power amplifier clockwise. If the sound distorts when the volume is turned up, turn the gain control counter-clockwise. Gain Control E Power Indicator B If you hear a beat while listening to an MW/LW broadcast with your car stereo, change the BFC switch using a small standard tip screwdriver.
