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 MUTE or
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 KSA utilizes 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 KSA has balanced and single-ended inputs
’.
The balanced inputs use 3-
pin XLR connectors and the single-ended inputs use standard RCA connec-
tors. We recommend use 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 KSA is shipped
with shorting pins in the XLR inputs. 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.
