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 : harman/kardonAVR 460/230 Service ManualPage 2 of 142RadioFans.CN 收音机爱 好者资料库7460Set upMICENGLISHFRONT-PANEL CONTROLSPower indicatorStandby/On SwitchInfo SettingsOKUSB PortDigital Audio Inputs (Optical and Coaxial Front)Headphone Jack/EzSet/EQ Microphone InputBack/ExitAudio EffectsSurround ModesAnalog Audio Front InputsKLNavigationM NNavigationRemote IR SensorSetupMessage DisplayVolumePower Indicator: This LED has three possible modes: Main Power Off : When the AVR is unplugged or the Main Power Switch is off, this LED is off.

It is usually left on, and cannot be turned on or off using the remote control.6-/8-Channel Inputs: Connect the multichannel analog audio outputs of a non-HDMI player (DVD-Audio, SACD, Blu-ray Disc or HD-DVD, or any other external decoder) to these jacks.Coaxial 1/2 and Optical 1/2/3 Digital Audio Inputs: If a source has a compatible digital audio output, and if you are not using an HDMI connection for audio for the device, connect it to one of these jacks to hear digital audio formats, such as Dolby Digital, DTS and linear PCM. Use only one type of digital audio connection for each source.Coaxial Digital Audio Output: If a source is also an audio recorder, connect the Coaxial Digital Audio Output to the recorders matching input for improved recording quality. Only PCM digital audio signals are available for recording. Both coaxial and optical digital audio signals are available at this Digital Audio Output.Zone 2 Infrared (IR) Input: Connect a remote IR receiver located in the remote zone of a multizone system to this jack to control the AVR (and any source devices connected to the Remote IR Output) from the remote zone.Remote Infrared (IR) Input and Output: When the remote IR receiver on the front panel is blocked, connect an optional IR receiver to the Remote IR Input jack. The Remote IR Output may be connected to the Remote IR Input of a compatible product to enable remote control through the AVR. Remote IR Carrier Output(AVR 460 only): This output is similar in function to the Remote IR Output, with the difference that this jack outputs the full infrared signal as received by the AVRs IR sensor or the Remote IR Input, while the Remote IR Output jack outputs a “stripped” signal that has no carrier frequency.HDMI Inputs and Output: HDMI (High-Definition Multimedia Interface) is a connection for transmitting digital audio and video signals between devices. Connect up to four HDMI-equipped source devices to the HDMI inputs using a single-cable connection.When you connect the HDMI Output to your video display, the AVR 460/AVR 360 will automatically transcode analog video signals to the HDMI format, upscaling to as high as 1080p. NOTES: When connecting a DVI-equipped display to one of the HDMI Outputs:Use an HDMI-to-DVI adapter. Make sure the display is HDCP-compliant. If it isnt, do not connect it to an HDMI Output; use an analog video connection instead.Always make a separate audio connection. Analog 1 5 Inputs: Connect the left and right analog audio outputs of a source device to any of these inputs. These inputs may be paired with any video inputs.NOTES: The Analog 2 and 4 inputs are each associated with a set of outputs. Consider using these connectors for an audio or video recorder. You may optionally connect a source to both an analog and digital audio input. This is useful for making recordings, for multizone applications or simply as a backup.Main Power Switch6-/8-Channel InputsRemote IR OutputCoaxial 1-2 Digital Audio InputsPreamp Outputs (AVR 460 only)Surround Back/Zone 2 Speaker OutputsFM AntennaAM AntennaZone 2 Audio OutputsSurround Speaker OutputsFront Speaker OutputsA-BUS PortA-BUS on AVR 460 onlyA-BUS Power InputHDMI 1-4 InputsHDMI Monitor OutputRemote IR InputCarrier IR Output (AVR 460 only)Video Monitor OutputSwitched AC Accessory OutletCenter Speaker OutputsA-BUS IR Output (AVR 460 only)Video 1-3 Inputsharman/kardonAVR 460/230 Service ManualPage 4 of 1421011InfoBack/ExitMenuOFFZR60LEARNSETUPINFOSLEEPENGLISHREMOTE CONTROL FUNCTIONSIR TransmitterMuteSource SelectorsTransport ControlsZone IndicatorMenuKLM N NavigationOKSleep SettingsAVR SettingsIR Transmitter LensAVR Power OffAVR Power OnDevice Power OnDevice Power OffVideo ModesSurround ModesActivityMenuKLM N NavigationOKDisc MenuChannelTransport ControlsSleep SettingsPower OffBack/ExitVolume ControlsZone SelectorSource SelectorsAudio EffectsAlphanumeric KeysLastBack/ExitLightSoft KeysVolumeMuteRecordInfo SettingsSetupZone SelectorThe AVR 460/AVR 360 remote is capable of controlling 8 devices, including the AVR itself and an iPod docked in The Bridge III. During the installation process, you may program the codes for your source components into the remote. To operate a component, press its Selector button to change the device mode.Each Source Selector has been preprogrammed to control certain types of components, with only the codes specific to each brand and model changing, depending on which product code is programmed. The AUX and Cable/SAT Source Selectors may be used for multiple device types. Other Source Selectors may be reassigned to other device types (see Initial Setup section).AUX Source Selector: CD player, VCR, HDTV set-top box, PVD or TiVo set-top box. Refer to page 23 for details on Source Selection.Cable/SAT Source Selector: Cable set-top box or satellite set-top box.IMPORTANT NOTE: All of the AVR 460/AVR 360s audio and video inputs are independently assignable. Select the inputs to which the device is physically connected during Initial Setup. Any device may be connected to any compatible input and given any name (e.g., DVD or Game). Most of the buttons on the remote have dedicated functions, although the precise codes transmitted vary, depending on the device mode. Due to the wide variety of functions for various source devices, only a few of the most-often used functions on the remote have been included: alphanumeric keys, transport controls, television-channel control, menu access, and power on and off.
