r_ DsP SURROUND SIMULATION• The AVR-3805 is equipped with a high performance DSP (Digital Signal Processor) which uses digital signal processing to synthetically recreatethe sound field. One of ten preset surround modes can be selected according to the program source and the parameters can be adjustedaccording to the conditions in the listening room to achieve a more realistic, powerful sound. These surround modes can also be used forprogram sources not recorded in Dolby Surround Pro Logic, Delby Digital or DTS.Select this to achieve an atmosphere like that of a movie theater with a large screen. In this mode, all signal sources are played1 WIDE SCREEN in the 7.1-channel mode, including Dolby Pro Logic and Dolby Digital 5.1-channel sources. Effects simulating the multi surroundspeakers of movie theaters are added to the surround channels.Select this when watching baseball or soccer programs to achieve a sound as if you were actually at the stadium. This mode2 SUPER STADIUM provides the longest reverberation signals.3 ROCK ARENA Use this mode to achieve the feeling of a live concert in an arena with reflected sounds coming from all directions.4 JAZZ CLUB 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.5 CLASSIC CONCERT Select this for the sound of a concert hall rich in reverberations.MONO MOVIE6 (NOTE 1) Select this when watching monaural movies for a greater sense of expansion.7 VIDEO GAME Use this to enjoy video game sources.Select this to emphasize the sense of expansion for music sources recorded in stereo. Signals consisting of the difference8 MATRIX component of the input signals (the component that provides the sense of expansion) processed for delay are output from thesurround channel.9 VIRTUAl Select this mode to enjoy a virtual sound field, produced from the front 2-channel speakersThe front left channel signals are output to the surround and surround back signal left channels, the front right channel signals are10 5CH/7CH STEREO output to the surround and surround back signal right channels, and the in-phase component of the left and right channels is outputto the center channel. Use this mode to enjoy stereo sound.._ 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 to your tastes.NOTE 1 : When playing sources recorded in monaural, the sound will be one-sided if signals are only input to one channel deft or right), so inputsignals to both channels. If you have a source component with only one audio output (monophonic camcorder, etc.) obtain a "Y" adaptorcable to split the meno output to two outputs, and connect to the L and R inputs.Personal Memory PlusThis set is equipped with a personal memorize function that automatically memorizes the surround modes and input modes selected for theinput different sources. When the input source is switched, the modes set for that source last time it was used are automatically recalled.•_ The surround parameters, tone control settings and playback level balance for the different output channels are memorized for eachsurround mode.80
