DSP sound modes16RQT5918Changing the recognition modeThe digital sound processor (DSP) in this unit can decode DolbyDigital and DTS digital signals. It automatically determines the typeof signal, PCM, Dolby Digital, or DTS, and processes it accordingly.The DSP can add surround-like effects to stereo sources (analog orPCM signals).Choose from the STEREO, SURROUND, or SFC modes.The DSP may interfere with radio reception. You can turn it off if thisoccurs (\ page 22).Output is in stereo when you turn the DSP off so sound is onlyheard through the front speakers.¡PCM with a sampling frequency of 44.1 kHz is the digital signalformat normally found on CDs. Some DVDs also use this formatbut often with a higher sampling rate.¡This unit cannot process other digital signal formats, such asPCM signals with sampling frequencies of 96 kHz and 192 kHzand MPEG.NoteUse this mode to play digital or analog stereo sources or to playsurround sources through two speakers. When surround sourcesare played in this mode, the sounds intended for the other speakerchannels are played through the front speakers.Select this mode when you are playing a digital surround source(Dolby Digital or DTS) or an analog source that is recorded withDolby Surround (VCR, for example).STEREO modeSURROUND modeIn rare cases, the unit may have trouble recognizing the digitalsignals on discs. With the PCM signals on CDs, this may cause thebeginning of a track to be cut off. Engage the PCM FIX mode if thisoccurs. With DTS, the signals may not be recognized at all. Engagethe DTS FIX mode if this occurs.This mode does not need to be changed under normalcircumstances. Change it only if the unit appears to be havingtrouble recognizing the software you are playing.While the input source is selected and digital input is engaged:Press and hold [DIGITAL INPUT].The current mode is displayed. Press again to change the mode.Each time you press the button:AUTO / PCM FIX / DTS FIX↑When a FIX mode is on, the unit cannot process other signals. Thismay cause noise to be output. Select "AUTO" if this occurs.The selected mode is stored even if the unit is turned off.DSP SOUND MODE DIGITAL INPUTABABCDSP SOUND MODESPEAKERSSOUND MODESTEREOL RADSP SOUND MODESPEAKERSDIGITALSOUND MODESURROUNDL C RLS LFE RSADIGITAL INPUTPCMFIXEDFIXEDC
