AX-ADCT4
Wire Color & Function: The audio and power input wire colors are an EIA standard for
car stereo applications as follows.
INPUT HARNESS POWER HARNESS
WHITE = LEFT Front (+) Input YELLOW = B12V Input
WHITE/BLACK = LEFT Front (-) Input BLACK = POWER (-) GROUND Input
GRAY = RIGHT Front + Input BLUE = 12V Output
GRAY/BLACK = RIGHT Front (-) Input BLACK/WHITE = Reference Ground(-)
GREEN = LEFT rear (+) Input
GREEN/BLACK = LEFT rear (-) Input
PURPLE = RIGHT rear (+) Input
PURPLE/BLACK = RIGHT rear (-) Input
OUTPUT HARNESS
WHITE = LEFT Front (+) Output
WHITE/BLACK = LEFT Front (-) Output
GRAY = RIGHT Front + Output
GRAY/BLACK = RIGHT Front (-) Output
GREEN = LEFT rear (+) Output
GREEN/BLACK = LEFT rear (-) Output
PURPLE = RIGHT rear (+) Output
PURPLE/BLACK = RIGHT rear (-) Output
NOTE: Be sure that all audio input connections are polarized or in phase with each other.
That is, the positive output wires from the audio source need to be connected to the cor-
responding positive input wires of the AX-ADCT4. The same goes for the negative audio
wires. Failure to do this will result in poor bass response and low quality audio.
Adjusting the AX-ADCT4 for maximum performance: After completing all of the neces-
sary connections, turn the AX-ADCT4 adjustment pots all of the way down by rotating
them completely counter-clockwise. Now, turn the stereo system on and adjust the main
volume control on the stereo to approximately ¾ maximum volume. Select one of the
adjustment pots on the AX-ADCT4 and turn it slowly clockwise until you notice audio
distortion and then stop. Turn the remaining pots to the same position as the previously
adjusted pot. The audio set-up of the AX-ADCT4 is now complete and ready to be
enjoyed.
