SHORTING BARS
The K2 S5800 is shipped with short-
ing bars installed between its low-
frequency and high-frequency
terminals. Please see Figure 10.
To prepare the
K2 S5800 for bi-wire
or bi-amp operation, these bars
must be removed by completely
unscrewing each binding post,
removing the bars, and replacing
the binding posts. Wires can then
be connected to each set of termi-
nals (see Figures 10 and 12).
AMPLIFIER
CONNECTIONS
IMPORTANT: Turn all amplifiers off
before connecting or disconnect-
ing
Project K2 S5800 loudspeakers.
Making connections while an
amplifier is operating could seri-
ously damage the loudspeaker
system and void the warranty. All
amplifiers must also be turned off
before connecting or disconnect-
ing cables at the amplifier or pre-
amplifier inputs.
All connections between the amp-
lifier(s) and the
Project K2 S5800
loudspeaker system are made at
the terminals located on the back
of the enclosure (see Figures 10
through 13). The left-hand termi-
nals (black stripe) are negative,
and the right-hand terminals (red
stripe) are positive. These corre-
spond to the negative and positive
conductors in the speaker wire.
Each speaker wire contains two
conductors, one of which will have
a stripe, color markings, or a ridge.
Assign one of the two conductors
as the negative conductor and the
other as the positive conductor.
Use these same designations for
all system wiring. Always connect
the conductors of the speaker wire
appropriately to the corresponding
negative and positive terminals on
all system components. This will
ensure that all components will
work together (“in phase”). Con-
necting the speakers out of phase
will not damage them but will
result in reduced low-frequency
output and impaired stereo effect.
Speaker wires may be fastened to
the terminals by several methods.
The most positive connection is
made by directly connecting clean,
bare connectors (exposed by strip-
ping the ends of the wire) to the
terminal posts.
For this type of connection, loosen
the knobs on the terminals and
insert the exposed (bare) ends of
each speaker wire into the hole
exposed on the terminal shaft
( + to +, – to – ) (see Figure 13).
Refasten the knob on each termi-
nal so that a snug connection is
achieved. Do not apply excessive
force and do not overtighten. To
avoid a short circuit, trim off any
excess wire that is not in contact
with the binding post contact
surfaces.
Project K2 S5800 terminals are
also designed to accept spade or
banana-type connectors which are
fastened to the ends of the wires
and, in turn, are attached to the
terminal posts.
WIRING
CONFIGURATIONS
As mentioned earlier, the Project
K2 S5800 speakers may be con-
nected to the amplifier(s) by one
of three methods: passive, bi-wire
and bi-amp. Each method, des-
cribed below, has its own advan-
tages, and the
Project K2 loud-
speaker system will deliver superb
performance with all methods.
Each speaker is shipped with
external shorting bars in place
(see Figure 10), connecting the
upper and lower terminal posts
on the left and right sides. These
bars must remain in place for
passive connections but must be
removed for all bi-wire and bi-amp
connections.
IMPORTANT: If the amplifiers are
connected to the Project K2 S5800
loudspeakers in the bi-wire or bi-
amp mode with the shorting bars
still on, the amplifier outputs will
be shorted, which could result in
costly amplifier damage when
power is switched on.
PASSIVE CONNECTION
METHOD
The passive method requires one
amplifier and one set of wires.
Connections are made to the lower
terminals (one black, one red). Do
not remove the shorting bars.
Loosen the lower terminal caps.
Connect the positive conductor to
the right (red) terminal and the
negative conductor to the left
(black) terminal (see Figures 11
and 13). Refasten the terminal caps.
