Note that the PowerIndicator surrounding the switch 3will turngreen when the unit is on.3Power Indicator:This LED will be illumi-nated in amber when the unit is in the Standbymode to signal that the unit is ready to beturned on.When the unit is in operation, theindicator will turn green.4Headphone Jack:This jack may be used tolisten to the AVR 2000s output through a pairof headphones. Be certain that the headphoneshave a standard 6.3 mm stereo phone plug.Note that the speakers will automatically beturned off when the headphone jack is in use.5Selector Buttons:When you are establish-ing the AVR 2000s configuration settings,usethese buttons to select from the choices available,as shown in the Main Information Display.6Tone Mode: Pressing this button enables ordisables the Balance, Bass and Treble tone con-trols.When the button is pressed so that thewords TONE INappear in the MainInformation Display, the settings of theBassand Treble*controls and of theBalance control &will affect the output sig-nals.When the button is pressed so that thewords TONE OUT appear in the MainInformation Display, the output signalwill be “flat, ” without any balance, bass or treblealteration.Front Panel Controls1234 5 67 8 9 )! # $ % & * ( Main Power SwitchSystem Power ControlPower IndicatorHeadphone JackSelector ButtonsTone ModeSurround Mode SelectorTuningTuner Band SelectorPreset Stations SelectorInput Source SelectorRDS Select ButtonDigital Optical 3 InputDigital Coax 3 InputVideo 4 input jacksBass ControlBalance ControlTreble ControlVolume ControlSet ButtonInput IndicatorsDelayDigital Input SelectorMain Information DisplayChannel Select ButtonSpeaker Select ButtonTest Tone SelectorSurround Mode IndicatorsRemote Sensor Window4135789)!#$%*&(2926AVR 2000 RDSRDSPTYCTRTTA4 FRONT PANEL CONTROLSFront Panel Controls7Surround Mode Selector: Press this but-ton to change the surround mode by scrollingthrough the list of available modes.

Pressing it again will switch between theAM and FM frequency bands, holding it pressedfor some seconds will switch between stereoand mono receiving and between automatic andmanual tuning mode (See page 29 for moreinformation on the tuner).)Preset Stations Selector: Press this but-ton to scroll up or down through the list of sta-tions that have been entered into the presetmemory. (See page 29 for more information ontuner programming.)!Input Source Selector: Press this buttonto change the input by scrolling through the listof input sources. RDS Select Button: Press this button to dis-play the various messages that are part of theRDS data system of the AVR 2000s tuner.(Seepage 30 for more information on RDS).#Digital Optical 3 Input: Connect the opti-cal digital audio output of an audio or video prod-uct to this jack.When the Input is not in use,becertain to keep the plastic cap installed to avoiddust contamination that might degrade future performance.$Digital Coax 3 Input:This jack is normallyused for connection to the output of portabledigital audio devices, video game consoles orother products that have a coax digital jack.%Video 4 Input Jacks: These audio/videojacks may be used for temporary connection tovideo games or portable audio/video productssuch as camcorders and portable audio players.Bass Control:Turn this control to modify thelow frequency output of the left/right channels byas much as 10dB.Set this control to a suitableposition for your taste or room acoustics.&Balance Control:Turn this control tochange the relative volume for the frontleft/right channels.NOTE: For proper operation of the surroundmodes this control should be at the midpoint or“12 oclock” position.*Treble Control:Turn this control to modifythe high frequency output of the left/right chan-nels by as much as 10dB.Set this control to asuitable position for your taste or room acoustics.(Volume Control:Turn this knob clockwiseto increase the volume, counterclockwise todecrease the volume. If the AVR is muted,adjusting volume control will automaticallyrelease the unit from the silenced condition.Set Button:When making choices duringthe setup and configuration process,press thisbutton to enter the desired setting as shown inthe Main Information Display into theAVR 2000s memory.The set button may also beused to change the display brightness.(See page 28.)Input indicators: A green LED will light infront of the input that is currently being used asthe source for the AVR 2000.Delay: Press this button to begin thesequence of steps required to enter delay timesettings. (See page 20 for more information ondelay times.)Digital Input Selector:When playing asource that has a digital output, press thisbutton to select between the Optical# ?and Coaxial$ ?Digital inputs. (See pages 25-27 for more information on digital audio.)Main Information Display:This displaydelivers messages and status indications to helpyou operate the receiver.
