5CH/7CH STEREO
Use this to enjoy video game sources.
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 mode to enjoy a virtual sound field, produced from the front 2-channel speakers.
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 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.

DSP SURROUND SIMULATION
Surround modes and their features
• The AVR-2805 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.
2 SUPER STADIUM
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.

CONCERT
Select this for the sound of a concert hall rich in reverberations.

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
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.

NOTES:
• The surround speaker setting can also be
changed with the SPEAKER button on the
remote control unit.
• When “Default” is selected and the CURSOR
left button is pressed, “CINEMA EQ.” and
“D.COMP.” are automatically turned off,
“ROOM SIZE” is set to “medium”, “EFFECT
LEVEL” to “10”, “DELAY TIME” to “30ms” and
“LFE” to “0dB”.
• The “ROOM SIZE” expresses the expansion
effect for the different surround modes in terms
of the size of the sound field, not the actual size
of the listening room.
• When playing PCM digital signals or analog
signals in the DOLBY PRO LOGIC II, DOLBY
PRO LOGIC IIx, DTS NEO:6 modes and the input
signal switches to a digital signal encoded in
Dolby Digital, the Dolby surround mode switches
automatically. When the input signal switches to
a DTS signal, the mode automatically switches to
DTS surround.
When the surround parameters are set using
the buttons on the main unit, stop operating
buttons after completing the settings. The
settings are automatically finalized and the
normal display reappears after several seconds.
When the settings are made using the buttons
on the remote control unit, press the “ENTER”
or “SURROUND PARAMETER” button to
finish.
