Operation
Inputs
All CKi series amplifiers use 3-Pin Phoenix connectors for attaching input sig-
nals. Each connector is configured (from left to right) positive,negative,
ground.
Input Phoenix Connectors
Outputs
Direct
Direct (speaker) outputs are connected to CKi series amplifiers via the
rear-panel terminal strips. Be sure to properly calculate the total
impedance of all speakers connected to a direct output and to not
exceed the minimum impedance rating of your CKi amplifier
Constant Voltage
For CKi-v and CKi-x models constant voltage (distributed) lines are
connected to via the same rear-panel terminal strips. Be sure to prop-
erly calculate the total wattage demand of each constant voltage line
and to not exceed the maximum output rating of your CKi amplifier.
Output Barrier Strip
See — the wiring diagrams on the next two pages for more information on
connecting your CKi amplifier.
Power
Unless otherwise specified when ordered,CKi Series amplifiers are shipped
from the factory set to one of following voltage options:
Option 1 US domestic
Nominal 120Vac 60Hz for rated power output (safe operating range
100 - 132Vac )
Option 2 Export
Nominal 230Vac 50Hz for rated power output (safe operating range
200 - 264Vac )
Very high current is
available at the outputs.
Please connect your
output cable to the +
and - terminals of each
section precisely as
shown.
a
In situations where an
UNBALANCED sig-
nal is fed to the amp,
it’s important to ground
the unused input.If the
inverting (-) input of an
amp channel is left float-
ing,the gain will drop
by 3 dB.
