DSP SURROUND SIMULATION
• The AVR-3805 is equipped with a high performance DSP (Digital Signal Processor) which uses digital signal processing to synthetically recreate
the sound field. One of ten preset surround modes can be selected according to the program source and the parameters can be adjusted
according to the conditions in the listening room to achieve a more realistic, powerful sound. These surround modes can also be used for
program sources not recorded in Dolby Surround Pro Logic, Dolby Digital or DTS.

WIDE SCREEN
5CH/7CH STEREO
Select this when watching baseball or soccer programs to achieve a sound as if you were actually at the stadium. This mode
provides the longest reverberation signals.
Use this mode to achieve the feeling of a live concert in an arena with reflected sounds 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 for the sound of a concert hall rich in reverberations.
Select this when watching monaural movies for a greater sense of expansion.
Use this to enjoy video game sources.
Select this to achieve an atmosphere like that of a movie theater with a large screen. In this mode, all signal sources are played
in the 7.1-channel mode, including Dolby Pro Logic and Dolby Digital 5.1-channel sources. Effects simulating the multi surround
speakers of movie theaters are added to the surround channels.
The front left channel signals are output to the surround and surround back signal left channels, the front right channel signals are
output to the surround and surround back signal right channels, and the in-phase component of the left and right channels is output
to the center channel. Use this mode to enjoy stereo sound.

MATRIX
VIRTUAL
Select this to emphasize the sense of expansion for music sources recorded in stereo. Signals consisting of the difference
component of the input signals (the component that provides the sense of expansion) processed for delay are output from the
surround channel.
Select this mode to enjoy a virtual sound field, produced from the front 2-channel speakers.
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 (left or right), so input
signals to both channels. If you have a source component with only one audio output (monophonic camcorder, etc.) obtain a “Y” adaptor
cable to split the mono output to two outputs, and connect to the L and R inputs.
Personal Memory Plus
This set is equipped with a personal memorize function that automatically memorizes the surround modes and input modes selected for the
input 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 each
surround mode.
