It is usually left pressed in (On position), and cannot be turned on using the remote control. Standby/On Switch:This electrical switch turns the receiver on for playback, or leaves it in Standby mode for quick turn-on using this switch or the remote control. Power Indicator:This LED has four possible modes: Main Power Off: When the AVR is unplugged or the Main Power Switch is off, this LED is off. Standby: The LED is amber, indicating that the AVR is ready to be turned on. On: The LED is white, when the AVR is on and operating normally. Protect: If the PROTECT message ever appears, turn off the AVR and unplug it. Check all speaker wires for a possible short. If none is found, bring the unit to an authorized Harman Kardon service center for inspection and repair before using it again. Source List:Press this button to select a source device, which is a component where a playback signal originates, such as DVD, cable TV, satellite or the tuner. Volume Knob:Turn this knob to raise or lower the volume. Message Display:Various messages 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 dis- play menu system (OSD) is in use, the current menu settings appear. Headphone Jack/EzSet/EQ Microphone Input:Plug a 1/4 headphone plug into this jack for private listening. This jack is also used to connect the supplied microphone for the EzSet/EQ procedure described in the Initial Setup section.To begin EzSet/EQ, plug the supplied microphone into this jack, place the micro- phone at the listening position, and follow the directions given in the Speaker Setup-Automatic Setup-EzSet/EQ on-screen menu. Surround Modes:Press this button to select a surround sound (e.g., multichannel) mode.The Surround Modes menu will appear on screen, and the menu line will appear in the front-panel display. Use the front-panel or remote /Buttons to highlight a different menu line:Auto Select,Virtual Surround, Stereo, Movie, Music or Video Game. Each line represents a type of audio signal, and is set to the preferred surround mode that you manually select. Press the OK Button when the menu line is highlighted, and the available surround mode options for the current signal will appear. Use the /Buttons to select the desired mode, and press the OK Button to engage it. Press the Back/Exit Button to exit the Surround Modes menu. See the Advanced Functions section for more information on surround modes. Analog Audio,Video and Digital Audio 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. NOTES: Each of these connections (analog audio, digital audio and video) may be independently assigned to any source. See the Initial Setup section for information on setting up sources, including assigning audio and video inputs to a source. Although these jacks are labeled Optical 3, Coaxial 3 and Video 4 on the AVR, the AVRs menus refer to them as the Optical Front, Coaxial Front, Composite Front, S-Video Front and Analog Front inputs. Speaker/Channel Input Indicators:The box icons indicate which speaker positions you have configured (see the Initial Setup Section), and the size (frequency range) of each speaker.The letters will light inside the boxes to indicate which channels are present in the incoming signal. Navigation:These buttons are used to navigate the AVRs menus and to operate the tuner. 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, such as when the AVR 254 is placed inside a cabinet, you may use an optional Harman Kardon HE 1000, or other infrared receiver, connecting it to the Remote IR Input on the AVR 254s rear panel.Alternatively, connect the Remote IR Output of another compatible component to the AVR 254s Remote IR Input. Point the remote at the other devices remote sensor, and the command will be transmitted to the AVR 254.An external IR “blaster” may also be used, positioned to point at this area. AVR Settings Button:Press this button to access the AVRs main menu. Info Settings Button:Press this button to directly access the AVRs Source Info submenu, which contains the settings for the current source. Resolution:Each press of this button changes the AVRs video output resolution to these settings: 480i, 480p, 720p, 1080i or 1080p. IMPORTANT NOTE: If the AVRs video output resolution is set higher than the capabilities of the actual connection, you will not see a picture. If the best video connection from the AVR to the TV is either composite or S-video, press this button until the resolution is set to 480i.

AVR254om.qxd 3/28/08 12:45 PM Page 10 8 AVR254 harman/kardonharman/kardon RadioFans.CN 收音机爱 好者资料库 REAR-PANEL CONNECTIONS AM and FM Antenna Terminals:Connect the included AM and FM antennas to their respective terminals for radio reception. XM Antenna Jack:Plug in an XM Connect and Play or Mini Tuner antenna module here.The XM antenna module is purchased separately, and should specify that it is for home use with an XM Readyproduct. You will need to subscribe to the XM service, which is available sepa- rately, and activate the service for your antenna module. (XM service is not available in Alaska and Hawaii.) Front, Center and Surround Speaker Outputs:Use two- conductor speaker wire to connect each set of terminals to the correct speaker. Remember to observe the correct polarity (positive and negative connections).Always connect the positive lead to the colored terminal on the receiver and the red terminal on the speaker. Connect the negative lead to the black terminal on both the receiver and the speaker. See the Connections section for more information on connecting your speakers. Surround Back/Zone 2 Speaker Outputs:These speaker outputs are used for the surround back channels in a 7.1-channel home theater, or may be reassigned to a remote room for multizone operation. When these outputs are reassigned for multizone operation, only a 5.1-channel configuration will be available in the main listening room. Use the on-screen menu system to configure these channels as desired. As with the other speaker outputs, remember to observe proper polarity by connecting the positive and negative output terminals to the corre- sponding terminals on each speaker. Subwoofer Output:If you have a powered subwoofer with a line-level input, connect it to this jack. 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 surround back channels, or to power the remote zone of a multizone system. Use the on-screen menu system to configure these channels as desired. Remote Infrared (IR) Input and Output:When the remote IR receiver on the front panel is blocked, such as when the AVR is placed inside a cabinet, connect an optional IR receiver to the Remote IR Input jack for use with the remote control.The Remote IR Output may be connected to the Remote IR Input of a compatible product to enable remote control through the AVR.This is particularly useful in multizone applications to control a source device from the remote room (when used with the Zone 2 IR Input).When several source devices are used, connect them in “daisy chain” fashion. 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. Composite and S-Video 1, 2 and 3 Video Inputs:These jacks may be used 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.These inputs are assignable, which means they may be paired with any analog or digital audio inputs.This will be explained in more detail in subsequent sections of this manual. NOTE: The Video 2 inputs are associated with a set of outputs. Consider connecting a video recorder here. Composite and S-Video 2 Outputs:Connect one of these analog video outputs to the composite or S-video inputs of a recording device.A signal is available at these outputs whenever an analog video source is playing. HDMI and component video signals are not available for recording. 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 your television or video display. If your video display is equipped with HDMI or component video inputs, these connections are unnecessary. Connect the HDMI Monitor Output (if available, otherwise use the Component Video Monitor Output) to your TV, and the AVR 254 will convert the composite or S-video source signal to the correct format for a single video cable connection to the TV. HDMI Inputs and Output:HDMI (High-Definition Multimedia Interface) is a connection for transmitting digital audio and video signals between devices.With the AVR 254s powerful processor, you may connect up to three HDMI-equipped source devices to the HDMI inputs using a single-cable connection, while benefiting from superior digital audio and video performance.If your video display is not HDMI-compatible, connect the device to one of the analog video inputs, then pair it with an analog or digital audio input. If your video display has an HDMI input, make just the HDMI video con- nection to your display; the AVR 254 will automatically transcode analog video signals to the HDMI format, upscaling to as high as 1080p. Analog 1 5:Connect the left and right analog audio outputs of a source device to any of these inputs.These inputs are assignable, which means they may be paired with any video inputs, as explained in subsequent sections of this manual. NOTES: The Analog 3 through 5 connectors physically line up below the Video 1 through 3 (composite and S-video) connectors. For convenience,consider using Analog 3 with Video 1,Analog 4 with Video 2 and Analog 5 with Video 3, if appropriate for your system. The Analog 1 and 2 connectors dont physically line up with any analog video inputs. Consider using them for audio-only devices, such as a CD player or cassette tape deck. The Analog 2 and 4 inputs are each associated with a set of outputs. Consider using the Analog 2 connectors for an audio recorder, and the Analog 4 connectors for a video recorder (along with the Video 2 connectors). 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.
