Notes on connections:
• Be sure to push all plugs firmly into their sockets.
Loose connections can cause hum and other
unwanted noises.
• Deploy all mains leads, loudspeaker cables and
remote control leads as far as possible from low-level
leads (inter-connects) and aerial cables. Never route
them over or under the decoder.
• Connect the unit to a correctly earthed mains socket
using the mains lead supplied.
• To achieve maximum possible interference rejection
the mains plug should be connected to the mains
socket in such a way that phase is connected to the
mains socket contact marked with a dot ( ). The
phase of the mains socket can be determined using a
special meter. If you are not sure about this, please
ask your specialist dealer.
• We recommend the use of the  'POWER LINE'
ready-to-use mains lead in conjunction with the
'POWER BAR'
mains distribution panel, which is
fitted with a phase indicator as standard.
As the decoder can be combined with a very wide range
of different AV components, it must be configured
carefully for each audio / video device in order to achieve
optimum sound and picture quality.
We recommend that you adopt the following procedure
when using the decoder for the first time:
a. Connect the TV set and the surround speakers to the
decoder (wiring diagram 1).
b. Integrate the digital surround decoder including
speakers and TV set into your existing Hi-Fi system.
c. The remaining wiring examples show how the various
analogue and digital picture and sound sources can
be connected to the digital surround decoder.
If you encounter problems when setting up and using the
decoder for the first time, please remember that the
cause is often simple, and equally simple to eliminate.
Please refer to the section of these instructions entitled
'
Trouble-shooting'.
