Surround speaker
• Set the front speakers with their front surfaces as flush
with the TV or monitor screen as possible. Set the center
speaker between the front left and right speakers and no
further from the listening position than the front speakers.
• Consult the operating instructions for your subwoofer for
advice on placing the subwoofer within the listening room.
• If the surround speakers are direct-radiating (monopolar)
then place them slightly behind and at an angle to the
listening position and parallel to the walls at a position 2 to
3 feet (60 to 90 centimeters) above ear level at the prime
listening position.
• Connect the surround speakers to the surround speaker A
terminals on the AVR-5805CI and set settings on the setup
menu to “A”. (This is the factory default setting (
page
153))
• The surround speakers can be switched freely during
playback with the surround parameter adjustment (
page 45).

Dolby Surround
The AVR-5805CI is equipped with a digital signal processing
circuit that lets you play program sources in the surround
mode to achieve the same sense of presence as in a movie
theater.
[1] Dolby Digital
Dolby Digital is the multi-channel digital signal format
developed by Dolby Laboratories.
A total of 5.1 channels are played: 3 front channels (“FL”,
“FR” and “C”), 2 surround channels (“SL” and “SR”) and the
“LFE” channel for low frequencies.
Because of this, there is no crosstalk between channels and a
realistic sound field with a “three-dimensional” feeling (sense
of distance, movement and positioning) is achieved.
A real, overpowering sense of presence is achieved when
playing movie sources in AV rooms as well.
[2] Dolby Pro Logic
II
Dolby Pro Logic II is a matrix decoding technology developed
by Dolby Laboratories. Regular music such as that on CDs is
encoded into 5 channels to achieve an excellent surround
effect.
The surround channel signals are converted into stereo and
full band signals (with a frequency response of 20 Hz to 20
kHz or greater) to create a “three-dimensional” sound image
offering a rich sense of presence for all stereo sources.
[3] Dolby Pro Logic
II
x
Dolby Pro Logic II x is a further improved version of the Dolby
Pro Logic
II
matrix decoding technology.
Audio signals recorded in 2 channels are decoded to achieve a
natural sound with up to 7.1 channels.
There are three modes: “Music” suited for playing music,
“Cinema” suited for playing movies, and “Game” which is
optimum for playing games.
[4] Dolby Headphone
This is a three-dimensional sound technology developed jointly
by Dolby Laboratories and Lake Technology Ltd. of Australia
for achieving surround sound using regular headphones.
Previously, when using headphones all the sounds resonated
inside the head and it was uncomfortable to listen with
headphones for long periods of time. Dolby Headphone
simulates speaker playback in a room and places the sound at
the front or the sides, outside the head, to achieve a powerful
sound like the sound of movie or home theaters. This
technology is mainly for multichannel audio/video equipment
with Dolby Digital or Dolby Pro Logic Surround decoding
functions and works with a high performance digital signal
processing (DSP) chip.
Dolby Headphone is effective not only for multichannel
sources but also for stereo programs.
On the AVR-5805CI, it is possible to output signals encoded in
the Dolby Headphone mode from the recording output
terminal and record them on a separate recorder.
