Vincent

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
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!
XLR connections
Please note that European and US-American XLR
signal assignments for the connector pins are dif-
ferent. 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
satisfy the same standard, the signal connection is
correct. 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.
INSTALLATION
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.
DURING INSTALLATION PLEASE OBSERVE
THE FOLLOWING ADVICE:
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.
Make sure that bare loudspeaker wires are never
able to come into contact with each other or with the
metal on the back of the housing. Ensure that bare
loudspeaker wires are never able to come into con-
tact with each other or with the metal on the back of
the housing.
Make sure that the positive and negative loudspea-
ker 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.
When using loudspeaker cable with 4 mm banana
plugs the factory security plugs in the speaker clamps
have to be removed prior first use.
Cable connections
Make sure that all plugs fit tightly. Inadequate con-
nections can cause noise interference, failures and
malfunctions.
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.
