[. . . ] Please read through these operating instructions so you will know how to operate your model properly. After you have finished reading the instructions, put them away in a safe place for future reference. In some countries or regions, the shape of the power plug may sometimes differ from that shown in the explanatory drawings. This product complies with the Low Voltage Directive (73/23/EEC, amended by 93/68/EEC), EMC Directives (89/336/EEC, amended by 92/31/EEC and 93/68/EEC). [. . . ] This settings establishes the size and configuration of the center speaker you have connected more exactly than the automatic setup. This will determine if bass sounds are sent by the receiver to the speaker being set. Large: If the cone size (diameter) of your speaker(s) is larger than 12 centimeters, set to Large. Small: If the cone size (diameter) of your speaker(s) is 12 centimeters or smaller, set to Small. None (­): Choose this setting if you have no speaker(s) hooked up to this terminal. Sound coming from this channel in the original source will be down-mixed to one of the active speakers. If the front speakers are set to Small (S) you can't choose Large (L) for the surround speakers. If the center and surround speakers are set to None (­) the listening modes for all the inputs will automatically go into AUTO mode. The Subwoofer setting divides the high and low sounds (frequencies) between the speakers. Since most smaller speakers can't handle deep bass tones, this setting allows you to send those sounds to the subwoofer instead of the speakers set to Small (S) in your system. Choose the point at which you want the frequency routed to the subwoofer. We recommend setting this to 200 Hz if smaller bookshelf-type speakers are used for your "Small" speakers. Also, when a subwoofer is used, you have the option of selecting the PLS setting, which adds extra bass. Use the +/­ buttons to choose a speaker setting according to the speakers you hooked up. If the front speakers are set to Small (S) you can't choose Large (L) for the center speaker. If the center and surround speakers are set to None (­) the listening modes for all the inputs will automatically go into AUTO mode. Use the +/­ buttons to choose subwoofer setting 100 Hz, 150 Hz, 200 Hz, PLS (plus) or ­ ­ ­ (off). Front speakers distance setting Set the distance from the front speakers to the listening position. Use the +/­ buttons to choose the distance of the front speakers from the main listening position (within a range from 0. If the all the speakers are set to Large (L) you can only select 100 kHz, PLS or off (­ ­ ­) for the Subwoofer. Setting the front speakers to Small (S) means you will use a subwoofer, thus its setting cannot be turned off. In this case make sure you set the subwoofer and choose its cutoff frequency. [. . . ] PCM can be used as one of the audio recording formats for DVD but as it's only 2 channel stereo. Determining what kind of playback format is being employed with any particular recording format depends on three things: 1) how the signal is encoded and transmitted; 2) how the signal is decoded; and 3) how the sound is actually heard through the speakers (where your speaker configuration and the sound mode you choose have a big effect). Used mainly for videotape, this is one of the original home theater formats and can be decoded by this receiver. because it developed over a time it is the most complicated system explained here.
