[] ADDITIONAL INFORMATION
There are currently various types of mulLi<hannel signals (signals or formats with more than two channels)
• Types of multi-channel signals
Doby Digital, DoBy Pro Logc, 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 nol refer to the type of signal (format) but the recorded content Sources can be divided
into two major categories
Types of sources
• Movie audio Signals created to be played in movie theaters In general sound s recorded to be played in
mowe theaters equipped with multiple surround speakers, regardless of the format (Doby
Digital, DTS, etc)

In this case it is important to achieve the same
sense of expansion as in a movie theater with
the surround channels
To do so, n some cases tile number of
surround speakers is increased {to four or

properties are used

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 funct on as "point" sound sources in the same way as the front
speakers
These two types of sources thus have d fferent properties, and different speaker settings, particularly for the
surround speakers, are required in order to achieve the ideal sound
A 61 <hannel system is a conventional 51 -chanr_el system to which the "surround back" (SB) channel has been
added This makes it easy to achieve sound positioned 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 is 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 61-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 bto 51-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
wellas Doby Digtal 5 %channel and DTS Surround 51<hannel sources Furthermore, allthe Denon original
surround modes (see page 30) are compatible with 71-channel playback, so you can eqoy 7 l<hannel sound
with any signal source
• Number of surround back speakers
Though the surround back channel only conssts of 1 channel of playback signals for 61-channel sources
(DTS-ES, etc), we recommend using two speakers When using speakers with dipolar characteristics in
particular, t is essential to use two speakers
Usng 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 olher than the center
• Placement of the surround left and right channels when using surround hack speakers
Usng surround back speakers greatly mproves the positioning of the sound at the rear Because of t_l_Sr t_le
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 signaB are also
produced from diagonal]y in front of the listeners, creathg an acoustic image as if the sound were floating =n
space
To achieve these effects, we recommend phcing the speakers for the surround left and right channels slightly
more towards the front than with conventional surround systems Doing so sometimes increases the
surround effect when playing conventional _ l-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
