27Basic Operation Basic Operation2 On screen displayChecking the currently playing program sourcePress the ON SCREEN button.Each time an operation is performed, a description of thatoperation appears on the display connected to AVR-3806’sVIDEO MONITOR OUT terminal. Also, the unit’s operatingstatus can be checked during playback.Such information as the position of the input selector andthe surround settings is output in sequence.2 Front panel displayPress the STATUS button.Descriptions of the unit’s operations are also displayed onthe front panel display. In addition, the display can beswitched to check the unit’s operating status while playing asource.2 Using the dimmer functionUse this to change the brightness of the display.Press the DIMMER button.The display brightness changes in four steps (bright,medium, dim and off).Input modeThe AVR-3806 has an AUTO signal detection mode thatautomatically identifies the type of incoming audio signals, but isalso equipped with a manual mode that can be switchedaccording to the type of input audio signals.2 Selecting the AUTO, PCM and DTS modesAUTO PCM DTSPress the INPUT MODE button.The mode switches as shown below each time the INPUTMODE button on the main unit is pressed:AUTO (All auto mode):In this mode, the types of signals being input to the digital andanalog input terminals for the selected input source aredetected and the program in the AVR-3806’s surrounddecoder is selected automatically upon playback. This modecan be selected for all input sources other than PHONO andTUNER.The presence or absence of digital signals is detected, thesignals input to the digital input terminals are identified anddecoding and playback are performed automatically in DTS,Dolby Digital or PCM (2 channel stereo) format. If no digitalsignal is being input, the analog input terminals are selected.Use this mode to play Dolby Digital signals.DTS (exclusive DTS signal playback mode):Decoding and playback are only performed when DTS signalsare being input.PCM (exclusive PCM signal playback mode):Decoding and playback are only performed when PCM signalsare being input.Note that noise may be generated when using this mode toplay signals other than PCM signals.STATUSINPUT MODE ANALOGDIMMER ROOM EQROOM EQINPUT MODEON SCREENAUTOEXT.IN ANALOGPCM DTSThe mode switches as shown below each time the INPUTMODE button on the remote control unit is pressed:(Remote control unit)When operating the remote control unit:ENGLISHENGLISH
