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 theparts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptablyinsulated 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 calledElectrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors andsemiconductor chip components.The following techniques should be used to help reduce the incidence of component damage caused by static electricity.1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge onyour 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 prior 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, toprevent electrostatic charge build-up or exposure of the assembly.3. Use only a grounded-tip soldering iron to solder 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 chargessufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacementES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to thechassis 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 bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing togetheror your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.CAUTION : AVR145 harman/kardonharman/kardon harman/kardonAVR 145/230 service manualPage 2 of 135RadioFans.CN 收音机爱 好者资料库2ELECTROSTATICALLY SENSITIVE DEVICESSAFETY PRECAUTIONSThe following check should be performed for the continuedprotection of the customer and service technician.LEAKAGE CURRENT CHECKMeasure leakage current to a known earth ground (waterpipe, conduit, etc.) by connecting a leakage current testerbetween the earth ground and all exposed metal parts of theappliance (input/output terminals, screwheads, metaloverlays, control shaft, etc.). Plug the AC line cord of theappliance directly into a 120V AC 60Hz outlet and turn theAC power switch on. Any current measured must not exceedo.5mA.ANY MEASUREMENTS NOT WITHIN THE LIMITSOUTLINED ABOVE ARE INDICATIVE OF APOTENTIAL SHOCK HAZARD AND MUST BECORRECTED BEFORE RETURNING THE APPLIANCETO THE CUSTOMER.DeviceundertestTest allexposed metalsurfacesAlso test withplug reversed(Using AC adapterplug as required)AC Leakage TestLeakagecurrenttesterReading shouldnot be above0.5mAEarthgroundharman/kardonAVR 145/230 service manualPage 3 of 135Technical Specifications AVR145/230Audio SectionStereo Mode Continuous Average Power (FTC)50Watts per channel, 20Hz20kHz, 0.07% THD, both channels driven into 8 ohms5 Channel Surround Modes Power Per Individual ChannelFront L&R channels:40Watts per channel, 0.07% THD, 20Hz20kHz into 8 ohmsCenter channel:40Watts, 0.07% THD, 20Hz20kHz into 8 ohmsSurround channels:40Watts per channel, 0.07% THD, 20Hz20kHz into 8 ohmsInput Sensitivity/Impedance Linear (High Level)200mV/47kohmsSignal-to-Noise Ratio (IHF-A)100dBSurround System Adjacent Channel Separation Analog Decoding 40dB (Pro Logic, etc.) Dolby Digital (AC-3) 55dB DTS55dBFrequency Response 1W (+0dB, 3dB)10Hz130kHzHigh Instantaneous Current Capability (HCC)25AmpsTransient Intermodulation Distortion (TIM)UnmeasurableRise Time16secSlew Rate40V/sec*FM Tuner SectionFrequency Range87.5108MHzUsable SensitivityIHF 1.3 V/13.2dBfSignal-to-Noise RatioMono/Stereo: 70/68dB (DIN)DistortionMono/Stereo: 0.2/0.3%Stereo Separation40dB 1kHzSelectivity400kHz: 70dBImage Rejection80dBIF Rejection90dBAM Tuner SectionFrequency Range5221620kHzSignal-to-Noise Ratio45dBUsable SensitivityLoop: 500VDistortion1kHz, 50% Mod: 0.8%Selectivity10kHz: 30dBVideo SectionVideo FormatPAL/NTSCInput Level/Impedance1Vp-p/75 ohmsOutput Level/Impedance1Vp-p/75 ohmsVideo Frequency Response(Composite and S-Video)10Hz8MHz (-3dB)Video Frequency Response (Component)10Hz100MHz (-3dB)GeneralPower RequirementAC 220240V/50HzPower Consumption65W idle, 540W maximum (5 channels driven) Dimensions (Max)Width440mm Height165mm Depth382mm Weight9.7 kgDepth measurement includes knobs, buttons and terminal connections.Height measurement includes feet and chassis.All features and specifications are subject to change without notice.Harman Kardon,The Bridgeand Logic 7 are registered trademarks of Harman International Industries, Incorporated.is a trademark of Harman International Industries, Inc.*Manufactured under license from Dolby Laboratories.“Dolby,”“Pro Logic” and the Double-D symbol are trademarks of Dolby Laboratories.DTS and DTS Neo:6 are registered trademarks of DTS,Inc. 96/24 is a trademark of DTS, Inc.SA-CD is a trademark of Sony Electronics, Inc.Apple and iPod are registered trademarks of Apple Computer, Inc.Cirrus is a registered trademark of Cirrus Logic Corp.*Without input anti slewing and output isolation networks.TMharman/kardonAVR 145/230 service manualPage 4 of 13545TROUBLESHOOTING GUIDESYMPTOMCAUSESOLUTIONUnit does not function when Main No AC Power Make certain AC power cord is plugged into Power Switch is pusheda live outlet Check to see whether outlet is switch-controlledDisplay lights, but no sound Intermittent input connections Make certain that all input and speaker connections or pictureare secure Mute is on Press Mute Button Volume control is down Turn up volume controlNo sound from any speaker; Amplifier is in protection mode Check speaker wire connections for shorts at receiver and light around power switch is reddue to possible shortspeaker ends Amplifier is in protection mode Contact your local Harman Kardon service centerdue to internal problemsNo sound from surround or Incorrect surround mode Select a mode other than Stereocenter speakers Input is monaural There is no surround information from mono sources Incorrect configuration Check speaker mode configuration Stereo or Mono program material The surround decoder may not create center- or rear-channel information from nonencoded programsUnit does not respond to Weak batteries in remote Change remote batteriesremote commands Wrong device selected Press the AVR selector Remote sensor is obscured Make certain front panel sensor is visible to remoteor connect an optional remote sensorIntermittent buzzing in tuner Local interference Move unit or antenna away from computers, fluorescent lights, motors or other electrical appliancesLetters flash in the channel indicator Digital audio feed paused Resume play for DVDdisplay and digital audio stops Check that Digital Input is selectedIn addition to the items shown above, additional information on troubleshooting possible problems with your AVR 145, or installation-related issues, maybe found in the list of Frequently Asked Questions which is located in the Product Support section of our Web site at .AVR 145 OM (New) 8/4/06 1:19 PM Page 45harman/kardonAVR 145/230 service manualPage 5 of 135NODESCRIPTIONPARTS NO.Q,ty123451ACCESSORY-1BOX,OUT CARTON5613DESCRIPTIONNOCPS4A564CQXAVR145/230CPG1A820W111Q,tyPARTS NO.CPS4A565SNOW,PAD(R)411.
