Connection Of The Loudspeakers - VINCENT SP-331 Instructions For Use Manual

CONNECTION OF THE LOUDSPEAKERS

You can connect one or two pairs of loudspeakers to the power amplifier SP-331. For each speaker the unit
provides two speaker terminals (positive + and negative –), each of which is connected to a pair of 2-core
speaker cables. At the loudspeaker connection terminal there are similar connector screws or connectors.
There, the polarity of each screw (+ or –) can be identified as well and the other side of the speaker cable
associated with this loudspeaker must be attached. Make sure only connector screws of the same polarity
will be connected by each speaker cable wire: a knob marked "+" in the amplifier's terminal must be con-
nected with a speaker's connector screw marked "+" as well.

If every speaker is connected in a conventional way (a two core speaker cable for each loudspeaker) and
you own loudspeakers that are equipped with Bi-Wiring terminals (four connector screws) you have to
make sure that the metal brackets (contact pieces consisting of small metal plates or short pieces of cable
which are supplied with the speakers) are applied to the terminal and that each one connects the two
knobs of the same polarity (e.g. both connectors marked "+"). The upper connector screw labelled "+"
and "R" at the amplifier's backside must be connected to one of the bridged, labelled "+" and "R" con-
nectors of the loudspeaker. Accordingly, the upper connector screw labelled "–" and "R" at the amplifier's
backside must be connected to one of the bridged, labelled "–" and "R" connectors of the loudspeaker.
Make a corresponding connection between the left speaker and the power amplifier. If a second pair of
loudspeakers is to be connected, then the clamps in the bottom row of the output terminals are connected
in a similar fashion to the additional loudspeaker. This is only permitted if both loudspeakers have a nomi-
nal impedance of at least 4Ω!
