Shorting Bars, Amplifier Connections

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.
