Connection, Wiring - T+A VSP 1250 R User Manual

Notes on connecting the system
• You will find a series of detailed wiring diagrams
towards the end of these instructions. Be sure to
connect all your equipment exactly as shown in the
appropriate diagram.
• Push all connectors firmly into their sockets. Loose
connections are often the cause of problems and
malfunctions.
Mains connection
• Please connect the machine to a suitable properly
earthed mains power socket.
• The VSP 1250 R must be connected to a mains power
socket whose voltage is as stated in the printed panel
adjacent to the mains socket.
• To achieve the maximum signal : noise ratio the mains
plug should be fitted in the mains socket in such a way
that the phase is connected to the socket contact which
is marked with a dot ( ). The phase of the mains
socket can be checked with a suitable device. If you are
not sure of this, please ask your specialist dealer.
Mains leads, mains filters
• We recommend the use of the  'POWER LINE'
mains cable in conjunction with the 'POWER BAR'
mains distribution panel; this panel features a phase
indicator as standard.
• The mains power supply carries the energy required by
your equipment, but at the same time it also bears
interference from remote equipment, including radios,
computer systems and energy-saving lamps.
Such interference can reduce overall sound and picture
quality, and our accessory range includes specially
shielded mains leads designed to keep it away from the
equipment. These include
shielded mains lead, the 'POWER LINE' ready-made
mains lead with ferrite ring filters, and the 'POWER
BAR' filtered mains distribution panel. With these
accessories the reproduction quality of our machines
can often be further improved.
Signal leads
• The HDMI cables you use have an influence on the
picture and sound quality of the overall system which
should not be underestimated. If your system features
long cables between the VSP 1250 R and the video
monitor in particular, it is absolutely essential to use a
high-quality HDMI or DVI lead to ensure that the picture
signal is transferred perfectly.
•  recommends the screw-fitting HDMI cables which
are included in the  accessory range. In addition to
excellent transmission quality, the screw-lock of these
cables ensures that the delicate HDMI connectors are
firmly seated. They therefore cannot come loose,
guaranteeing freedom from contact problems over a
period of many years.
• If you have any questions relating to cables, please ask
your local  specialist dealer, where you will find
competent, comprehensive and unbiased advice. We
would also be glad to send you detailed information on
this subject.

Connecting the monitor
• Please connect your HDMI or DVI video monitor to the
HDMI or DVI output of the VSP 1250 R, using a high-
quality HDMI or DVI lead. Low-quality leads are often
the cause of problems with HDMI / DVI transmission
systems.

Note:
You can also connect two monitors to the HDMI
and DVI outputs of the VSP 1250 R. Please
note, however,
(resolution, aspect ratio etc.) generated at both
outputs is identical. It is therefore necessary to
use two monitors which are suitable for the
same signals and resolutions.
• Deploy the HDMI / DVI lead to the monitor carefully,
without kinking it (minimum bend radius > 10 cm),
otherwise there may be transfer problems with the
extremely high signal frequencies (up to 1.5 GHz)
which are used with these cables. In an extreme case
the result may be that the screen stays dark, or just
displays "snow" or picture "noise".
Connections to a surround receiver
• Analogue picture sources can send your picture signals
to the VSP 1250 R via your surround receiver. In this
case the analogue picture signals are digitised in the
VSP 1250 R, and sent to your video monitor via the
DVI / HDMI cable. This arrangement saves you the
complication of deploying multiple analogue and digital
cables to the monitor.
• To make use of this facility, connect the video outputs
of your receiver (Composite, S-Video or YUV,
according to features) to the appropriate inputs of the
VSP 1250 R.
• If you are using a B receiver or decoder (SR 1535 R,
DD 1535 R), please note that you must connect the S-
Video output of the receiver or decoder to the AV2 input
on the VSP 1250 R, as the on-screen menus of the
receiver or decoder are transferred to the monitor via the
VSP 1250 R using this connection.
• If you are using an all-B system, please connect an
R cable to the rest of the B system, so that the
LINK
VSP 1250 R is incorporated in the overall control
system.
• If you also wish sound signals to be reproduced by the
video monitor which is connected to the HDMI output of
the VSP 1250 R (e.g. if it is set up in an adjacent room),
then the sound signals to be transferred must be
present in digital form at the AUDIO IN input of the
VSP 1250 R. This is achieved by connecting a digital
audio output at your receiver to the DIGITAL AUDIO IN
input of the VSP 1250 R. Please note that the signal
supplied by this route must be in a format which the
monitor can process, e.g. Stereo PCM sound.

Note:
B surround receivers generate a PCM
stereo downmix signal at their digital audio
outputs; this is compatible with all video
panels.
