INANALOG8(Remote control unit)Input mode selection functionDifferent input modes can be selected for the differentinput sources. The selected input modes for theseparate input sources are stored in the memory.q AUTO (All auto mode)In this mode, the types of signals being input to thedigital and analog input jacks for the selected inputsource are detected and the program in the AVR-1802’s surround decoder is selected automaticallyupon playback. This mode can be selected for allinput sources other than TUNER.The presence or absence of digital signals isdetected, the signals input to the digital input jacksare identified and decoding and playback areperformed automatically in DTS, Dolby Digital orPCM (2 channel stereo) format. If no digital signalis being input, the analog input jacks are selected.Use this mode to play Dolby Digital signals.w PCM (exclusive PCM signal playback mode)Decoding and playback are only performed whenPCM signals are being input.Note that noise may be generated when using thismode to play signals other than PCM signals.e DTS (exclusive DTS signal playback mode)Decoding and playback are only performed whenDTS signals are being input.r ANALOG (exclusive analog audio signal playbackmode)The signals input to the analog input jacks aredecoded and played.t EXT. IN (external decoder input jack selection mode)The signals being input to the external decoderinput jacks are played without passing through thesurround circuitry.NOTE:• Note that noise will be output when CDs or LDsrecorded in DTS format are played in the “PCM”(exclusive PCM signal playback) or “ANALOG”(exclusive analog audio signal playback) mode.Select the AUTO or DTS (exclusive DTS signalplayback) mode when playing signals recorded inDTS from a laser disc player.Notes on playing a source encoded with DTS• Noise may be generated at the beginning ofplayback and while searching during DTSplayback in the AUTO mode. If so, play in theDTS mode.• In some rare cases noise may be generated whenyou preform the operation to stop playback ofa DTS-CD or DTS-LD.ENGLISHSelect the play mode.Press the SURROUND MODE button, then turnthe SELECT knob.3SURROUNDMODE(Main unit) (Remote control unit)SELECTTo select the surround mode whileadjusting the surround parameters,channel volume or tone control,press the surround mode buttonthen operate the selector.

However,when the channel level is set as described onpage 15, if the volume for any channel is setat +1 dB or greater, the volume cannot beadjusted up to 18 dB. (In this case themaximum volume adjustment range is “18dB — (Maximum value of channel level)”.)Input mode when playing DTS sources• Noise will be output if DTS-compatible CDs or LDsare played in the “ANALOG” or “PCM” mode.When playing DTS-compatible sources, be sure toconnect the source component to the digital inputjacks (OPTICAL/COAXIAL) and set the input modeto “DTS”.Input mode displayANALOGDIGITALDIGITALDIGITALANALOGAUTO PCM DTSINPUTAUTO PCM DTSINPUTAUTO PCM DTSINPUTAUTO PCM DTSINPUT• In the AUTO mode• In the DIGITAL PCM mode• In the DIGITAL DTS mode• In the ANALOG modeOne of these lights, dependingon the input signal.Input signal displaySIGNALDIGITALDIGITALDIGITALSIGNALSIGNAL• DOLBY DIGITAL• DTS• PCMThe indicator lights when digital signalsare being input properly.
