5. SPEAKERS: Loudspeaker terminals
At these output sockets with threaded terminals
one or two loudspeakers can be connected.
Speaker cable with 4 mm banana plugs can be
used. Please take note of the information given in
the section “Installation”, if two loudspeakers will
be connected to the amplifier.
6. LINE IN:
Input for preamplified mono audio signal
One connector of this input must be connected
with the output connector of the preamplifier for
the desired channel. For example, connected with
“PRE OUT R”, if the SP-995 is to be used for the
loudspeaker of the right-hand stereo channel.
Only one of the two input connectors can be used
at any time. The setting “XLR IN” (4) must have
been chosen correctly. Do not connect any line
level sources!
7. POWER CONTROL: ON/OFF control
These jack connectors (3.5 mm) receive and for-
ward the signal for the standby control (12V
Trigger). As soon as a “POWER CONTROL” con-
nection is made at the “POWER CONTROL” con-
nector panel only the connected breaker signal
determines if the SP-995 is turned on or in stand-
by mode. The button “POWER”(2) on the front
panel is inoperable.
8. AC power connector and fuse holder
To establish the power supply, connect the plugs
of the power cable to the device and to the AC
wall outlet. The small plastic housing beneath the
plug opening holds the fuse. Refer to the security
precautions.

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!
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 4
Ω
.
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
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:
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.
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.
