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 :AVR 1650 AVR 1650 harman/kardonharman/kardonRadioFans.CN 收音机爱 好者资料库SAFETY 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 above0.5mAEarthgroundA AVR 1650 VR 1650 harman/kardonharman/kardon3AVR 1650/AVR 165SpecificationsSpecificationsAudio SectionStereo power:95W per channel, two channels driven 8 ohms, 20Hz 20kHz, 0.07% THDMultichannel power:95W per channel, two channels driven 8 ohms, 20Hz 20kHz, 0.07% THDInput sensitivity/impedance:200mV/47k ohmsSignal-to-noise ratio (IHF-A):100dBSurround system adjacent-channel separation:Dolby Pro Logic/PLII: 40dB Dolby Digital: 55dB DTS: 55dBFrequency response:10Hz 130kHz (+0dB/3dB)High instantaneous-current capability (HCC): 25 ampsTransient intermodulation distortion (TIM):UnmeasurableSlew rate:40V/secFM Tuner SectionFrequency range:87.5 108.0MHzUsable sensitivity IHF:1.3V/13.2dBfSignal-to-noise ratio (mono/stereo):70dB/68dBDistortion (mono/stereo):0.2%/0.3%Stereo separation:40dB 1kHzSelectivity (400kHz):70dBImage rejection:80dBIF rejection:90dBAM Tuner SectionFrequency range:520 1720kHzSignal-to-noise ratio:45dBUsable sensitivity (loop):500VDistortion (1kHz, 50% mod):0.8%Selectivity (10kHz):30dBVideo SectionTelevision format:NTSC (AVR 1650); PAL (AVR 165)Input level/impedance:1Vp-p/75 ohmsOutput level/impedance:1Vp-p/75 ohmsVideo frequency response (composite video):10Hz 8MHz (3dB)HDMI:Version 1.4a with 12-bit Deep ColorGeneral SpecificationsPower requirement:120V AC/60Hz (AVR 1650); 220V 240V AC/50Hz 60Hz (AVR 165)Power consumption:0.5W (standby); 280W maximum Dimensions (W x H x D): 17-5/16 x 6-1/2 x 17-1/8 (440mm x 165mm x 435mm)Weight20 lb (9.1kg)AVR 1650 AVR 1650 harman/kardonharman/kardon4FOAM PAD, (L)FOAM PAD, (R)AVR 1650OUTER CARTONFOAM PAD, (L)FOAM PAD, (R)AVR 1650AVR 1650 h harman/kardonarman/kardon5AVR 1650/AVR 165Front-Panel ControlsFront-Panel ControlsPower IndicatorMessage DisplayVolume KnobSurround Mode Select ButtonsSet ButtonIR SensorPower ButtonLeft/Right ButtonsHeadphone Jack/ EzSet/EQ Mic ConnectorSource Select ButtonsTuning Mode ButtonDigital Input ButtonSurround-Mode Category ButtonUp/Down Buttons/ Tuning ButtonsUSB PortAux Analog Audio Input ConnectorChannel Level Control ButtonA AVR 1650 VR 1650 harman/kardonharman/kardon6AVR 1650/AVR 1655Front-Panel Controls, continuedFront-Panel Controls, continuedPower indicator: This LED has three possible modes: LED is off: Indicates that the AVR is unplugged or the rear-panel Main Power switch is off.

Notes on using the HDMI Monitor Out connector: When connecting a DVI-equipped display to the HDMI Monitor Out connector, use an HDMI-to-DVI adapter and make a separate audio connection. Make sure the HDMI-equipped display is HDCP-compliant. If it isnt, do not connect it via HDMI; use an analog video connection instead and make a separate audio connection.HDMI Input connectors: The HDMI (High-Definition Multimedia Interface) feature is a connection for transmitting digital audio and video signals between devices. If your source devices have HDMI connectors, using them will provide the best possible video and audio performance quality. Since the HDMI cable carries both digital video and digital audio signals, you do not have to make any additional audio connections for devices you connect via HDMI connections. See Connect Your Source Devices, on page 13, for more information.Composite Video Monitor Out connector: If your TV or video display does not have an HDMI connector, or if your TV does have an HDMI connector but you are connecting some source devices with only composite video connectors, use a composite video cable (not included) to connect the AVRs Composite Video Monitor Out connector to your TVs composite video input connector. DVD Component Video Input connector: If your Blu-ray Disc or DVD player does not have an HDMI connector but does have a component video connector, using the component video connector will provide superior video performance. You will also need to make an audio connection from the player to the AVR.Digital Audio Input connectors: If your non-HDMI source devices have digital outputs, connect them to the AVRs digital audio connectors. NOTE: Make only one type of digital connection (HDMI, optical or coaxial) from each device. See Connect Your Source Devices, on page 13, for more information.Video 2 Out connector: Connect an analog video recorders video input connector to the AVRs Video 2 Out connector. You can record any composite video input signal. NOTE: To record the audio and video from the source device, connect the AVRs Video 2 Out Analog Output connectors to the analog video recorders audio inputs.Composite Video Input connectors: Use composite video connectors for video source devices that dont have HDMI or component video connectors. You will also need to make an audio connection from the source device to the AVR. See Connect Your Source Devices, on page 13, for more information.IR Remote In/Out connectors: When the IR Sensor on the front panel is blocked (such as when the AVR is installed inside a cabinet), connect an optional IR receiver to the IR Remote In connector. The IR Remote Out connector may be connected to the IR input of a compatible product to enable remote control through the AVR. See Connect IR Equipment, on page 15, for more information.The Bridge IIIP connector: Connect an optional Harman Kardon The Bridge IIIP docking station to this connector. Insert the plug until it snaps into place in the connector. IMPORTANT: Connect The Bridge IIIP only with the AVRs power turned off. See Connect The Bridge IIIP, on page 15, for more information.Subwoofer connector: Connect this jack to a powered subwoofer with a line-level input.
