INSTALLATION

Pre- and main amplifier compose the amplifier used in
High-End systems. They must be interconnected.
Your loudspeakers will be connected to the main amplifier, your
audio sources to the pre-amplifier. To achieve best performance
only quality interconnection cables as produced by Vincent should
be utilized. Consult your audio specialist dealer.
Remove plastic protective covers
Prior to the first installation, remove the plastic
protective covers on RCA and XLR connectors.

Connections
Input connectors for audio source devices and out-
put connectors for the main amplifier are mechani-
cally identical RCA jacks that must not be inter-
changed!
Connection quality
Make sure all connections are tight. Loose connec-
tions may cause noise, failure or malfunctions.
Connect carefully
Contacting the middle pin of the RCA plugs at the
pre/main interconnection cable with the outer ring
of the RCA chassis jack may lead to damages to
the main amplifier if it is active! To avoid this hazard,
connect or disconnect both devices only in switched-
off state and more than one
minute after deactivating!
Inputs
The most often used device or the audio source
providing best sound quality should be connected
to the balanced input. This way
of signal connection is more

robust and less sensible to
radiated noise.

XLR Input
Note that European and US-American XLR signal
assignments are different! This pre-amplifier uses the
European system. Both variants use identical cables.
BALANCE
If both connected devices use the same type, the
signal connection is correct (Always, if both devices
have been produced by Vincent). For the connection
of two devices using the opposite system a diffe-
rent cable must be used to avoid inverting of both
channel signals. Contact your dealer for more in-
formation and support.

RCA Connection
At most audio equipment, RCA connectors are color-
coded using red for the right channel and white or
black for the left channel.
CD-Player connection
Bear in mind that the signal into the „balanced"
input (XLR) is not being transferred to the REC-
Output. It is not possible to make a recording from
a CD-Player (for example) connected there via the
Recording Output.
MAIN AMPLIFIER CONNECTION
You can choose between symmetrical (using RCA connectors) or unsymmetrical (using XLR connectors)
interconnection of your pre- and power-amplifiers. Up to four main amplifier channels can be connected.
So more than two loudspeakers can be supplied or two speakers can be used biwiring or biamping them.
Choose the appropriate setup for your system:
UNSYMMETRICAL CONNECTION
Unsymmetrical connection of one or
more main amplifiers
With all equipment switched off, connect the RCA
cables to the pre-amplifier outputs marked with
„1" in the „output" terminal and on the other side
of the cable(s) to the main amplifier RCA inputs

SYMMETRICAL CONNECTION
Symmetrical connection of two main
amplifier channels
Connect two XLR cables to the pre-amplifier outputs
marked with „balanced" in the „output" terminal
and on the other side of the cables with the main
amplifier XLR inputs (often marked as „Input",
„Balanced IN" oder „Power Amp IN"). Make sure
to not interchange right and left channels.
Letters „R" and „L" show you the assignments.

When connecting four amplifier channels additio-

„2" in the same way.
