ADDITIONAL
INFORMATION
There are currently various types of multi-channel
signals {signals or formats with more than two channels)
• Types of multi-channel
signals
Dolby Digital,
Dolby Pro Logic, DTS, high definition
3-1 signals
(Japan MUSE Hi-Vision audio), DVD-Audio,
SACD (Super Audio CD), MPEG multi-channel
audio, etc
"Source"
here does not refer to the type of signal (format) but the recorded content
Sources can be divided
into two maior categories
Types
of sources
• Movie
audio
Signals created to be played in movie theaters
In general sound is recorded to be played in
movie theaters
equipped
with multiple
surround
speakers, regardless
of the format (Dolby
Digital, DTS, etc)

In this case if is important to achieve the same
sense of expansion
as in a movie theater
with
the sunound
channels
To do
so, in some
cases
the
number
of
surround
speakers
is increased
(to four
or
eight)
or speakers
with
bipolar
or dipolar
properties
are used
\ SB: Surround back channel
• Other types of audio
These
signals
are designed
to recreate
a 360 ° sound field using three
to five
speakers¸
SL
SR
In this
case
the
speakers
should
surround
the
listener
from
all sides
to
create
a uniform
sound
field
from
360°¸
Ideally
the
surround
speakers
should
function
as
"point"
sound
sources
in the
same
way
as the
front
speakers¸
These two types of sources thus have different
properties,
and different
speaker settings,
particularly
for the
surround speakers, are required in order to achieve the ideal sound
A 6 1+channel system is a conventional
5 1-channel System to which the "surround
back" (SB) channel has been
added
This makes
it easy to achieve
sound
poskioned
directly
behind
the listener,
something
that was
previously
difficult
with
sources designed
for conventional
multi surround
speakers
In addition, the acoustic
image extending
between
the sides and the rear _s narrowed,
thus greatly improving
the expression
of the
surround signals for sounds moving from the sides to the back and from the front to the point directly behind the
listening position

With this set, speaker(s) for 1 or 2 channels are required to achieve a 6 1-channel system (DTS+ES, etc)
Adding
these speakers, however,
increases the surround
effect not only with sources recorded in 61 channels but also
with conventional
2- to 5 t-channel
sources
The WIDE SCREEN mode is a mode for achieving surround sound
with
up to 71 channels using surround
back speakers, for sources recorded
in conventional
Dolby Surround as
well as Dolby Digital 5 1-channel and DTS Surround
5 1-channel sources
Furthermore,
all the Denon original
surround
modes {see page 31) are compatible
with
7 1+channel playback, so you can enjoy 7 1-channel sound
with any signal source
•
Number
of surround
back
speakers
Though
the
surround
back
channel
only
consists
of
1 channel
of playback
signals
for 6 1+channel
sources
{DTS-ES,
etc),
we
recommend
using
two
speakers¸
When
using
speakers
with
dipolar
characteristics
in
particular,
it is essential
to use two
speakers¸
Using
two
speakers
results
in a smoother
blend
with
the sound
of the
surround
channels
and
better
sound
positioning
of the
surround
back
channel
when
listening
from
a position
other
than
the
center¸
•
Placement
of the
surround
left
and
right
channels
when
using
surround
back
speakers
Using
surround
back
speakers
greatly
improves
the
positioning
of the
sound
at the
rear¸
Because
of this,
the
surround
left
and right
channels
play an important
role in achieving
a smooth
transition
of the acoustic
image
from
the front
to the back¸
As shown
on the
diagram
above,
in a movie
theater
the surround
signals
are also
produced
from
diagonally
in front
of the
listeners,
creating
an acoustic
image
as if the
sound
were
floating
_n
space¸
To achieve
these
effects,
we
recommend
placing
the speakers
for the sur_und
left and
right
channels
slightly
more
towards
the
front
than
with
conventional
surround
systems¸
Doing
so
sometimes
increases
the
surround
effect
when
playing
Conventional
51-channel
sources
in the
61
surround
or DTS-ES
Matrix
61
mode¸
Check
the
surround
effects
of the various
modes
before
selecting
the
surround
mode¸
