Installation - VINCENT SP-994 Manuel D'utilisation

Set up the cable links in a sequence as follows. Connect the power cable between device
and power supply only after all other connections have been made.
Protective caps
Prior to the first installation the protective plastic
caps must be removed from all the connections
used at the rear of the unit.
RCA connections
Make sure that you do not mix up the analogue
inputs for right and left. The RCA plugs for these
are mostly colour coded as follows: red for the
right channel, black or white for the left channel.
Contacting the middle pin of the RCA plugs with
the outer ring of the RCA chassis jack may lead to
damages to the main amplifier if it is switched on!
To avoid this hazard, connect or disconnect only
in switched-off state and more than one minute
after deactivating!
Speaker cable connections
The use of ready-made loudspeaker cables is recom-
mended instead of connecting the cable's central
wire (strand) directly to the terminals. Banana plugs
or cable lugs ensure high security from short-circuits
and damage to loudspeakers or amplifier.
Ensure that bare loudspeaker wires are never able
to come into contact with each other or with the
metal on the back of the housing.
Make sure that the positive and negative loud-
speaker wires are connected correctly. You will
notice a reduced sound quality if the connections
are the wrong way round.
Only use loudspeakers with a nominal impedance
of at least 4Ω.
If you use loudspeaker cable equipped with 4mm
banana plugs you are required to remove the
small plastic plugs located in the connector holes
of the speaker clamps when first installing this
main amplifier in your system.

DURING INSTALLATION PLEASE OBSERVE
THE FOLLOWING ADVICE:

XLR connections
Please note that European and US-American XLR
signal assignments for the connector pins are diffe-
rent. This Vincent preamplifier uses the European
system following the standard AES14-1992. The
cable structure is the same in any case. As long as
both the preamplifier and the power amplifier satis-
fy the same standard, the signal connection is cor-
rect. This is always the case if both units were
made by Vincent. If two units from different stan-
dards are connected, this inverts the signal. In this
case the signal assignment on one side of the con-
nection has to be changed. Your audio specialist
dealer will support you with this.

To make the most of the components' sound poten-
tial, only high quality loudspeakers and connecting
cables, for example Vincent cables, should be
used. Your local stockist will be glad to advise you
about this.
