27345671VIDEO GAMEROCK ARENAJAZZ CLUBVIRTUALMATRIX5CH/6CHSTEREOUse this to enjoy video game sources.Use this mode to achieve the feeling of a live concert in an arena with reflectedsounds coming from all directions.This mode creates the sound field of a live house with a low ceiling and hard walls.This mode gives jazz a very vivid realism.Select this mode to enjoy a virtual sound field, produced from the front 2-channelspeakers or headphones.Select this to emphasize the sense of expansion for music sources recorded instereo. Signals consisting of the difference component of the input signals (thecomponent that provides the sense of expansion) processed for delay are outputfrom the surround channel.In this mode, the signals of the front left channel are output from the left surroundchannel, the signals of the front right channel are output from the right surroundchannel, and the same (in-phase) component of the left and right channels is outputfrom the center channel. This mode provides all speaker surround sound, butwithout directional steering effects, and works with any stereo program source.14 DSP SURROUND SIMULATIONSurround modes and their features• This unit is equipped with a high performance DSP (Digital Signal Processor) which uses digital signalprocessing to synthetically recreate the sound field. One of 7 preset surround modes can be selected accordingto the program source and the parameters can be adjusted according to the conditions in the listening room toachieve a more realistic, powerful sound. These surround modes can also be used for program sources notrecorded in Dolby Surround Pro Logic, Dolby Digital or DTS.2 MONO MOVIE(NOTE 1) Select this when watching monaural movies for a greater sense of expansion.Depending on the program source being played, the effect may not be very noticeable.In this case, try other surround modes, without worrying about their names, to create a sound field suited toyour tastes.NOTE 1: When playing sources recorded in monaural, the sound will be one-sided if signals are only input to onechannel (left or right), so input signals to both channels. If you have a source component with only oneaudio output (monophonic camcorder, etc.) obtain a “Y” adapter cable to split the mono output to twooutputs, and connect to the L and R inputs.Personal Memory PlusThis set is equipped with a personal memorize function that automatically memorizes the surround modesand input modes selected for the input different sources. When the input source is switched, the modes setfor that source last time it was used are automatically recalled.The surround parameters, tone control settings and playback level balance for the different outputchannels are memorized for each surround mode.NOTE:DIRECT, STEREO and 5CH/6CH STEREO mode can be used when playing PCM signals with a samplingfrequency of 96 kHz (such as from DVD-Video discs that contain 24 bit, 96 kHz audio). If such signals are inputduring playback in the other surround modes, the mode automatically switches to STEREO.ENGLISHSurround parameters wCINEMA EQ. (Cinema Equalizer):The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating foroverly-bright sounding motion picture soundtracks. Select this function if the sound from the front speakersis too bright.This function only works in the Dolby Pro Logic II, Dolby Digital and DTS Surround modes. (The samecontents are set for all operating modes.)D.COMP. (Dynamic Range Compression):Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loudsounds). For listening late at night, or whenever the maximum sound level is lower than usual, the DynamicRange Compression allows you to hear all of the sounds in the soundtrack (but with reduced dynamic range).(This only works when playing program sources recorded in Dolby Digital.) Select one of the four parameters(“OFF”, “LOW”, “MID” (middle) or “HI” (high)). Set to OFF for normal listening.LFE (Low Frequency Effect):This sets the level of the LFE (Low Frequency Effect) sounds included in the source when playing programsources recorded in Dolby Digital or DTS.If the sound produced from the subwoofer sounds distorted due to the LFE signals when playing Dolby Digitalor DTS sources when the peak limiter is turned off with the subwoofer peak limit level setting (system setupmenu), adjust the level as necessary.Program source and adjustment range:1. Dolby Digital: –10 dB to 0 dB2. DTS Surround: –10 dB to 0 dBWhen DTS encoded movie software is played, it is recommended that the LFE LEVEL be set to 0 dBfor correct DTS playback.When DTS encoded music software is played, it is recommended that the LFE LEVEL be set to –10dB for correct DTS playback.SB CH OUT (Surround Back):“OFF” ......................Playback is conducted without using the surround back speaker.“ON”........................Playback is conducted using the surround back speaker.NOTE: This operation can be performed directly using the “SURROUND BACK” button.
