8FRONT-PANEL CONTROLSMain Power Switch: This mechanical switch turns the power supplyon or off. It is usually left pressed in (On position), and cannot be turnedon using the remote control.Standby/On Switch: This electrical switch turns the receiver onfor playback, or leaves it in Standby mode for quick turn-on using thisswitch or the remote control.Power Indicator: This LED has three possible modes:• Main Power Off: When the AVR is unplugged or the Main PowerSwitch is off, this LED is off.• Standby: The LED is amber, indicating that the AVR is ready tobe turned on.• On: The LED is white, when the AVR is on and operating normally.NOTE: If the PROTECT message ever appears, turn off the AVRand unplug it. Check all speaker wires for a possible short. Ifnone is found, bring the unit to an authorized Harman Kardonservice center for inspection and repair before using it again.Source List: Press this button to select a source device, whichis 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 displayin response to commands and changes in the incoming signal. In normaloperation, the current source name appears on the upper line, while thesurround 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 theEzSet/EQ procedure described in the Initial Setup section. To beginEzSet/EQ, plug the supplied microphone into this jack, place the micro-phone at the listening position, and follow the directions given in theSpeaker 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 onscreen, and the menu line will appear in the front-panel display.Use the front-panel or remote ⁄/¤ Buttons to highlight a differentmenu line: Auto Select, Virtual Surround, Stereo, Movie, Music or VideoGame. Each line represents a type of audio signal, and is set to thepreferred surround mode that you manually select.Press the OK Button when the menu line is highlighted, and theavailable surround mode options for the current signal will appear.Use the ⁄/¤ Buttons to select the desired mode, and press theOK Button to engage it. Press the Back/Exit Button to exit the SurroundModes menu.See the Advanced Functions section for more information on surroundmodes.Analog Audio, Video and Digital Audio Inputs: Connect asource component that will only be used temporarily, such as a digitalcamera or game console, to these jacks. Use only one type of audioand one type of video connection.NOTES:• Each of these connections (analog audio, digital audio andvideo) may be independently assigned to any source. See theInitial Setup section for information on setting up sources,including assigning audio and video inputs to a source.• Although these jacks are labeled Optical 4, Coaxial 3 andVideo 4 on the AVR, the AVR’s menus refer to them as theOptical Front, Coaxial Front, Composite Front, S-Video Frontand Analog Front inputs.Speaker/Channel Input Indicators: The box icons indicatewhich speaker positions you have configured (see the Initial SetupSection), and the size (frequency range) of each speaker. The letterswill light inside the boxes to indicate which channels are present inthe incoming signal.Navigation: These buttons are used to navigate the AVR’s menusand to operate the tuner.Remote IR Sensor: This sensor receives infrared (IR) commandsfrom the remote control. It is important to ensure that it is not blocked.If covering the sensor is unavoidable, such as when the AVR 354 isplaced inside a cabinet, you may use an optional Harman KardonHE 1000, or other infrared receiver, connecting it to the Remote IRInput on the AVR 354’s rear panel. Alternatively, connect the Remote IROutput of another compatible component to the AVR 354’s RemoteIR Input. Point the remote at the other device’s remote sensor, and thecommand will be transmitted to the AVR 354. An external IR “blaster”may also be used, positioned to point at this area.AVR Settings Button: Press this button to access the AVR’smain menu.Info Settings Button: Press this button to directly access theAVR’s Source Info submenu, which contains the settings for thecurrent source.Resolution: Each press of this button changes the AVR’s video outputresolution to these settings: 480i, 480p, 720p, 1080i or 1080p.IMPORTANT NOTE: If the AVR’s video output resolution is sethigher than the capabilities of the actual connection, you will notsee a picture. If the best video connection from the AVR to theTV is either composite or S-video, press this button until theresolution is set to 480i.Audio Effects: Press this button to directly access the Audio Effectssubmenu, which allows adjustment of the tone and other controls.See the Initial Setup section for more information.Video Modes: Press this button for direct access to the Video Modessubmenu, which contains settings that may be used to improve thepicture if necessary after you have adjusted the picture settings usingthe video display or TV.OK: Press this button to select the currently highlighted item.Back/Exit: Press this button to return to the previous menu, orto exit the menu system.
