CHAPTER 8
Project K2 S9900 Connections
Caution: Turn all amplifiers off before connecting or disconnecting the
K2 S9900 loudspeakers. Making connections while an amplifier is operating
could seriously damage the loudspeaker system and void the warranty. All
amplifiers must also be turned off before connecting or disconnecting cables
at the amplifier or preamplifier inputs. All connections between the amplifier(s)
and the K2 S9900 loudspeaker system are made at the terminals located on the
back of the enclosure. The left-hand terminals (black insulator) are negative,
and the right-hand terminals (red insulator) are positive. These correspond to
the negative and positive conductors in the speaker wire.
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”). Connecting 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 often made by directly connecting clean, bare connectors
(exposed by stripping 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) end of each speaker wire into the hole exposed on the terminal
shaft (+ to +, – to –). Retighten the knob on each terminal so that a snug positive
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.
K2 S9900 terminals are also designed to accept spade- or banana-type connec-
tors, which are fastened to the ends of the wires and, in turn, are attached to the
terminal posts.
Two sets of input terminals on the K2 S9900 are designed for use with bi-wire and
bi-amp connections. Read the following explanations and use the suitable method.
