CONNECTIONS

INPUT AND OUTPUT CONNECTIONS

CAUTION:When making connections to this component or any other, make

sure the power amplifier is OFF and the preamplifier is in the MUTEor STAND-BY mode.

The wiring to and from the amplifier, and all components in, general, should

be arranged in a neat, organized manner. Specifically, AC wires should be separated from audio wires. This practice avoids hum or other unwanted noise from being induced into the system.

1. Connect the speaker cables to the amplifier's output terminals.

The KSAutilizes two custom sets of parallel binding posts for the left and

right channels respectively. This configuration makes cable connections and bi-wiring simple. The binding post will only accept a spade lug or ring terminal of proper inner radius. Bare wire, banana lugs or pins will not work. Each binding post is labeled either (+) or (-) between the sets of posts on rear panel. The (+) sign between the binding posts indicates the positive output terminal. This is commonly referred to as red or hot. The (-) sign between the binding posts indicates the negative output terminal. This is commonly referred to as black or ground.

CAUTION:Make sure all cable terminations are of the highest quality, free from frayed ends, shorts or cold solder joints.

2.Connect the interconnect cables from your preamplifier to the input of the KSA.

The KSAhas balanced and single-ended inputs '. The balanced inputs use 3-

pin XLRconnectors and the single-ended inputs use standard RCAconnec- tors. Werecommenduse of balanced interconnects sonically, and electrically because of their ability to reduce noise and not incur significant sonic loss due to extreme cable lengths.

CAUTION:Use only one input to the amplifier at a time. The KSAis shipped with shorting pins in the XLRinputs. These pins should remain in the XLR

inputs if you are operating the KSA in the single-ended mode. When the shorting pin is inserted, pin 1 and pin 3 are shorted together. The shorting pins must be removed to connect the KSA for balanced operation.
