Loudspeaker configurations for the DD 1535 R
The
DD 1535 R
features a digital decoder which is capable
of decoding all sound formats currently in use. The output
can be via a stereo speaker pair, a three-channel (stereo +
centre) set or a 5, 6 or 7-channel surround loudspeaker
set.
Regardless of the loudspeaker configuration you use in
your home, the
DD 1535 R
ensures that no recorded
sound information is ever lost.
For example, if a 6.1 recording is played back using a 3.0
loudspeaker set (front left, front right, front centre), the
DD 1535 R
mixes the rear channel information onto the
loudspeakers which are actually present, maintaining
correct levels and phase. The information of the LFE (Low
Frequency Effects) channel, i. e. of the 1. channel, is also
mixed onto the channels which are present. You therefore
hear everything contained in the original recording.
However, if rear speakers are not present in your system,
the surround effects cannot be reproduced. You therefore
do not sit in the middle of events, but more as if in a
theatre in front of an acoustic stage, on which the action
takes place.
For the genuine surround experience you require at least a
5-channel loudspeaker set - with or without a sub-woofer.
To ensure that the
SR 1535 R
is able to distribute the
information in all recordings correctly to your individual
loudspeaker combination, it is important that you enter the
correct settings in the Loudspeaker Configuration menu
when installing your system, i. e. which loudspeakers are
present and connected, what size they are, and how far
they are located from the listening position. It is also
essential to calibrate the loudspeakers so that they
reproduce the signals at exactly the right volume. This
ensures that sound effects take place exactly at the
position intended by the film director. With the loudspeaker
con-figuration menu you can also compensate for
differences in sound between individual loudspeakers,
e. g. when speakers have to be set up in the corners of the
room. To simplify the speaker configuration process as
much as possible the
SR 1535 R
features an
'Assistant'
which carries out most of the work for you fully
automatically, i. e. level calibration, tone settings and
speaker distances (see the chapter
'
Auto Setup
'
).
Picture norms, connecting AV devices to the DD 1535 R
There are several different picture norms designed for
transferring video data. The most common ones are:
Video (also sometimes referred to as FBAS or CVBS), S-
Video (also known as Y/C or S-VHS) and Component
Video (common abbreviations YUV, Y Pb Pr or Y Cb Cr).
Video is supported by virtually all source devices, TV sets,
monitors and video recorders. It is therefore the most
universal method of connecting video devices to each other,
but unfortunately also provides the worst quality of all.
S-Video offers a significant improvement in picture quality
over Video. If monitor and source device permit, the S-Video
connection should always be preferred.
The absolute best picture quality is obtained using
Component Video. However, Component Video is not
supported by video recorders, and only a few TV sets
feature the appropriate inputs. Component Video is
primarily used to connect DVD players to high-quality
projectors, or other large-format monitors.
The
DD 1535 R
offers sockets for all three video norms
listed above. It can also convert Video into S-Video, and S-
Video into normal video signals. As the owner of an
DD 1535 R
you therefore do not need to limit yourself to
standard Video as the “lowest common denominator” for all
your video equipment. You can connect any devices to the
DD 1535 R
, no matter what the picture norms, and use them
together. The
DD 1535 R
always automatically sets the best
possible connection between source, monitor and video
recorder.
With its integral norm converter the
DD 1535 R
automatically ensures that, for example, a normal video
signal is fed to a standard video recorder when making a
recording, even if the source device generates S-Video
signals. With the
DD 1535 R
this also works the other
way round: if you own an S-Video recorder, the
DD 1535 R
always ensures that an S-Video recording
signal is available for it - regardless of whether the
source device supplies an S-Video signal or only a
standard Video signal.
The
DD 1535 R
also carries out a norm conversion for
the video monitor connected to it. Regardless of what
your source device generates, the correct video signal is
always available for your monitor.
To ensure that the
DD 1535 R
is able to manage the
various picture signals correctly, it is essential to enter
the type of signal - Video or S-Video - which the source
device supplies when you are installing each device to
be connected to the machine (see the chapter
'
Configuration / Video Inputs
'
).
Available as an option: YUV converter module
The YUV converter module converts all Video and S-
Video input signals to YUV output signals. If this module
is present, all video signals are sent as YUV signals to
the monitor and the additonal Video / S-Video cables to
the monitor can be omitted. For details about the YUV
converter module ask your dealer or distributor.
