33ENGLISH18 ADDITIONAL INFORMATIONOptimum surround sound for different sourcesThere are currently various types of multi-channel signals (signals or formats with more than two channels).2 Types of multi-channel signalsDolby Digital, Dolby Pro Logic, DTS, high definition 3-1 signals (Japan MUSE Hi-Vision audio), DVD-Audio,SACD (Super Audio CD), MPEG multi-channel audio, etc.“Source” here does not refer to the type of signal (format) but the recorded content. Sources can be dividedinto two major categories.2 Types of sources• Movie audio Signals created to be played in movie theaters. In general sound is recorded to beplayed in movie theaters equipped with multiple surround speakers, regardless of theformat (Dolby Digital, DTS, etc.).FL CSW FRFL CSW FRSL SRSBSL SRSBMultiple surround speakers(For 6.1-channel system)Movie theater sound fieldListening room sound fieldIn this case it is important to achieve the samesense of expansion as in a movie theater with thesurround channels.To do so, in some cases the number of surroundspeakers is increased (to four or eight) or speakerswith bipolar or dipolar properties are used.SL: Surround L channelSR: Surround R channelSB: Surround back channel• Other types of audio These signals are designed to recreate a 360° sound field using three to fivespeakers.In this case the speakers should surround the listener from all sides to create auniform sound field from 360°. Ideally the surround speakers should function as“point” sound sources in the same way as the front speakers.FL CSW FRSL SRThese two types of sources thus have different properties, and different speaker settings, particularly for thesurround speakers, are required in order to achieve the ideal sound.NOTES:• If step 3 does not work, start over from step 1.• If the microprocessor has been reset, all thebutton settings are reset to the default values(the values set upon shipment from the factory).21, 217 INITIALIZATION OF THE MICROPROCESSORWhen the indication of the display is not normal or when the operation of the unit does not shows the reasonableresult, the initialization of the microprocessor is required by the following procedure.1 Switch off the unit using the main unit’s powerswitch.2 Hold the following SPEAKER A button and Bbutton, and turn the main unit’s power switch.3 Check that the entire display is flashing with aninterval of about 1 second, and release yourfingers from the 2 buttons and the microprocessorwill be initialized.16 LAST FUNCTION MEMORY• This unit is equipped with a last function memory which stores the input and output setting conditions as theywere immediately before the power is switched off.• The unit is also equipped with a back-up memory. This function provides approximately one week of memorystorage when the main unit’s power switch is off and with the power supply cord disconnected.RT (Radio Text)“RT” appears on the display when radio text data isreceived.When the RT button is pressed while receiving an RDSbroadcast station, the text data broadcast from thestation is displayed. To turn the display off, press theRT button again. If no text data is being broadcast,“NO TEXT DATA” is displayed.“RT”
