4、mponents identified 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.

5、 Leakage-current 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 ca

6、lled Electrostatically 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. Immedia

7、tely before 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 r

8、easons 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, to prevent electrostatic charge build-up or exposure of the assembly. 3. Use only a grounded-tip soldering iron

9、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 charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to d

10、amage ES devices. 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. Imm

11、ediately before 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. Mi

12、nimize bodily 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.

26、 Audio, Video and Analog Audio Front Inputs: Connect a source component that will only be used temporarily, such as a digital camera or game console, to these jacks. Use only one type of audio and one type of video connection. Note: The AVRs menus refer to these jacks as the Optical Front, Coaxial F

27、ront, Composite Front, S-Video Front and Analog Front inputs. EzSet/EQ II Microphone Input: This jack is used to connect the supplied microphone for the EzSet/EQ II procedure described in the Initial Setup section. Volume Knob: Turn this knob to raise or lower the volume. Message Display: Various me

28、ssages appear in this two-line display in response to commands and changes in the incoming signal. In normal operation, the current source name appears on the upper line, while the surround mode is displayed on the lower line. When the on-screen display menu system (OSD) is in use, the current menu

29、settings appear. Remote IR Sensor: This sensor receives infrared (IR) commands from the remote control. It is important to ensure that it is not blocked. If covering the sensor is unavoidable, use an optional Harman Kardon HE 1000, or other infrared receiver, connecting it to the Remote IR Input on

30、the AVR 760/ AVR 660s rear panel. AVR 660 -760, 230V Service Manual Page 9 of 264 RadioFans.CN 9 ENGLISH REAR-PANEL CONNECTIONS 6-/8-Channel Inputs Optical 1, 2 use an analog video connection instead. Always make a separate audio connection. Analog 1 5 Inputs: Connect the left and right analog audio

31、 outputs of a source device to any of these inputs. These inputs may be paired with any video inputs. NOTES: The Analog 3 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

32、digital audio input. This is useful for making recordings, for multizone applications or simply as a backup. Analog 3 and 4 Outputs: Connect either of these analog audio outputs to the analog audio inputs of a recording device. A signal is available at these outputs whenever an analog audio source i

33、s playing. Zone 2 Audio Outputs: Connect these jacks to an external amplifier to power the speakers in the remote zone of a multizone system. Subwoofer 1 and 2 Outputs: If you have a powered subwoofer with a line-level input, connect it to the Subwoofer 1 Output. For improved performance, connect a

34、second powered subwoofer to the Subwoofer 2 Output (Subwoofer 2 on AVR 760 only). The Bridge II Input: Connect the included Harman Kardon docking station to this input for use with most docking iPod models, 4G and later (not included). Turn the receiver off (Standby mode) when connecting The Bridge

35、II. Fan Vents: This area contains vents used by the AVR 760/AVR 660s fan to cool the system. Maintain a clearance of at least 8 cm from the nearest surface to avoid overheating the unit. It is normal for the fan to remain off at most normal volume levels. An automatic temperature sensor turns the fa

36、n on only when it is needed. IMPORTANT NOTE: Never block the fan vents, as doing so could allow the AVR to overheat to dangerous levels. Zone 2 Video Output: Connect this composite video jack to a video display located in the remote zone of a multizone system. When the multizone system is in use, vi

37、ewers in the remote zone will be able to see the AVRs on-screen text menus and any available source video, as long as the source is connected to a Composite Video Input, and that input is specified for that source in the Zone 2 Video setting of the Info Settings menu (AVR 760 only). Composite and S-

38、Video 1, 2 and 3 Video Inputs: Use these jacks to connect your video-capable source components (e.g., VCR, DVD player, cable TV box) to the receiver. Use only one type of video connection for each source. Composite and S-Video 2 Outputs: Connect one of these analog video outputs to the composite or

39、S-video inputs of a recording device. A signal is available at these outputs whenever an analog video source is playing. Composite and S-Video Monitor Outputs: If any of your sources use composite or S-video connections, connect one or both of these monitor outputs to the corresponding inputs on you

40、r video display. If your video display is equipped with HDMI or component video inputs, these connections are unnecessary, as the AVR 760/AVR 660 will convert the composite or S-video source signal to the correct format for a single video-cable connection to the TV. Component Video 1, 2 and 3 Inputs

41、: If a video source has analog component video (Y/Pb/Pr) capability, and if you are not using an HDMI connection, connect the component video outputs of the source to one of the sets of component video inputs. Do not make any other video connections to that source. Component Video Monitor Outputs: I

42、f you are using one of the Component Video Inputs and your television or video display is component- video-capable (but does not have HDMI), connect these jacks to the video display. NOTES: Due to copy-protection restrictions, there is no output at the Component Video Monitor Outputs for copy-protec

43、ted sources. Composite and S-video signals are upscaled to as high as 1080i and available at these outputs. If your video displays best connection is component video, it is the only video connection required from the AVR to the display. AM and FM Antenna Terminals: Connect the included AM and FM ant

44、ennas to their respective terminals for radio reception. Preamp Outputs: Connect these jacks to an external amplifier if more power is desired. The Surround Back/Zone 2 Preamp Outputs may be used with an external amplifier to power the remote zone of a multizone system. A-BUS Port: Use a Category 5/

45、5e cable to connect this port to optional A-BUS equipment for multizone operation. When the A-BUS system is used, it is possible to have a full 7.2-channel system in the main listening room at the same time the multizone system is in use. Front, Center and Surround Speaker Outputs: Use two- conducto

46、r speaker wire to connect each set of terminals to the correct speaker. Remember to observe the correct polarity (positive and negative connections). Surround Back/Zone 2 Speaker Outputs: These speaker outputs are used for the surround back channels in a 7.2-channel home theater, or may be reassigne

47、d to a remote room for multizone operation. Switched AC Accessory Outlet: You may plug the AC power cord of one source device into this outlet, and it will turn on whenever you turn on the receiver. Do not use a source that consumes more than 50 watts of power. AC Power Input: After you have made al

48、l other connections, plug the AC power cord into this receptacle and into an unswitched wall outlet. A-BUS Power Input: When using optional A-BUS equipment, connect an optional A-BUS power supply to this port.
