CONNECTION OF THE LOUDSPEAKERS
You can connect one or two pairs of loudspeakers to the power amplifier SP-20. 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.
SP-20
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
amplifier's backside must be connected to one of the bridged, labelled "-" and "R" connectors of the loud-
speaker. Make a corresponding connection between the left speaker and the power amplifier. Additionally,
the speaker connectors "A" must be activated at the front panel button "SPEAKER A" (3). If a second pair of
loudspeakers is to be connected, then the clamps in the bottom row of the output terminals "SPEAKER B" are
connected 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 8Ω!
