CONNECTION OF THE LOUDSPEAKERS
You can connect one loudspeaker the usual way (via a two-core speaker cable) to the power amplifier SP-
998. Some music enthusiasts may want to connect the speaker in “bi-wiring”.
For each speaker the unit provides two speaker terminals (2x po and 2x negative –). One end of
a conventional loudspeaker cable must be connected to one pair of those. Both terminal pairs (the two
upper connectors and the two lower connectors) are parallel and receive the same mono signal. 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 connected with a
speaker's connector screw marked “+” as well. SP-998 can only process the signal of one individual chan-
nel, for further channel(s) (mostly L or R, but sometimes CENTER etc.) additional main amplifiers are nee-
ded. The diagram shows the connections for one speaker.
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 “+”
at the amplifier's backside must be connected to one of the bridged, labelled “+” connectors of the loud-
speaker. Accordingly, the upper connector screw labelled “–” at the amplifier's backside must be connec-
ted to one of the bridged, labelled “–” connectors of the loudspeaker.
If a second loudspeaker is to be connected, then the clamps in the bottom row of the output terminals
“SPEAKER” are connected in a similar fashion to the additional loudspeaker. However, this is only per-
mitted if both loudspeakers have a nominal impedance of at least 8
Ω
