CONNECTION OF THE LOUDSPEAKERS
You can connect one or two pairs of loudspeakers to the power amplifier SP-331MK. For each speaker the
unit provides two speaker terminals (po 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 connec-
tors. 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 pola-
rity will be connected by each speaker cable wire: a knob marked “+” in the amplifier's terminal must be
connected 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 connector screw labelled “SPEAKER A”, “+” and “R”
at the amplifier's backside must be connected to one of the bridged, labelled “+” and “R” connectors of the
loudspeaker. Accordingly, the neighbouring connector screw labelled “SPEAKER A”, “-” and “R” at the ampli-
fier'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. Additionally, the spea-
ker connectors “A” must be activated at the front panel button “SPEAKER A” (3). If a second pair of loud-
speakers is to be connected, then the clamps in the bottom row of the output terminals “SPEAKER B” are con-
nected in a similar fashion to the additional loudspeaker. This loudspeaker pair is activated by switching on
the “SPEAKER B” button (3) on the front of the unit. However, this is only permitted if both loudspeakers have
a nominal impedance of at least 8
Ω
