Please have Customers contact harman/kardon directly at (516) 255-4545 to obtain warr

5、anty service. This service manual is being made available for units that are no longer under warranty, and products that are serviced outside the U.S. During testing, do not inject an audio signal frequency into the unit higher than 20kHz with no load. Peaking in the output filter can cause the outp

6、ut voltages to exceed the filter capacitor voltage rating in this design. Normal audio program material will not have enough energy to cause problems. Avoid test tones above 20kHz. The following pages 8 - 27, reprinted from the DPR2005 owners manual, are accurate for every feature and operation of b

7、oth the DPR1005 and DPR2005 with the following exception: The only feature difference between the two models is located in the front accessory jacks. On the 2005 the Front-panel digital coaxial/optical jacks may be used as either Inputs or Outputs. Those same jacks on the 1005 are for Inputs only; t

8、herefore there is also a missing indicator light for this function. For an accurate explanation of these jacks, refer to the DPR1005 owners manual.

9、dentified with the IEC symbolin the parts list are special significance to safety. When replacing a component identified with , use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the parts list in this manual. Leakage-c

10、urrent or resistance measurements must be made to determine that exposed parts are acceptably insulated from the supply circuit before retuming the product to the customer. Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elect

11、rostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and semiconductor chip components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity. 1. Immediately befor

12、e handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons pri

13、or to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge build-up or exposure of the assembly. 3. Use only a grounded-tip soldering iron to solder

14、or unsolder ES devices. 4. Use only an anti-static solder removal device. Some solder removal devices not classified as anti-static can generate electrical charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES d

15、evices. 6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.) 7. Immediately b

16、efore removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed. Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bod

17、ily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

45、verall system power output specification. The GR70 is designed to meet FTC power amplifier specifications for a sine wave continuous power measurement with all chan- nels driven. Under normal conditions for most applications, all channels may not need to be driven at full power simultaneously. More

46、typically, the power output requirement is 1/8 to 1/3 of the total amplifier output. However, if the amplifier is allowed to be driven into high distortion (“clipping”), the power supply current may approach 20% more than required for a full scale out- put. It is therefore up to the system designer to determine how
