A
LOC60
i
s designed to convert speaker level audio to line level audio.This allows for the instal-
l
ation of line level products such as amplifiers, EQs and crossovers on systems that do not have
RCA line level outputs.
F
eatures:
3
0 Watts Maximum Input, Input Circuit Corrects Crossover Distortion Commonly
Found On Other Brands of LOCs, 6:1 Step Down with Variable Output, Gold Flashed RCAs,
A
ttractive & Durable Enclosure
Installation: The ALOC60 should be installed on a stereo’s speaker output wires or the output
w
ires on an OEM amplifier of up to 30 watts per channel. These wires can be found behind the
stereo in the dash, on the outside of an OEM amplifier, or on the input terminals on the OEM speak-
e
rs. This device is most commonly installed in the trunk when a subwoofer system is being added
t
o the OEM stereo system.
W
ire Color & Function:
T
he audio input wire colors are an EIA standard for car stereo applications
a
s follows:
INPUT HARNESS: WHITE = LEFT Front (+) Input
W
HITE/BLACK
=
LEFT Front (-) Input
GRAY = RIGHT Front + Input
G
RAY/BLACK
=
RIGHT Front (-) Input
B
LACK
=
Reference Ground (-)
N
OTE:

e sure that all audio input connections are polarized or in phase with each other. That is,
t
he positive output wires from the audio source need to be connected to the corresponding posi-
tive input wires of the ALOC60 The same goes for the negative audio wires. Failure to do this will
r
esult in poor bass response and low quality audio.
A
djusting the ALOC60 for maximum performance:
A
fter completing all of the necessary connec-
tions, turn the ALOC60 adjustment pots all of the way down by rotating them completely counter-
c
lockwise. Now, turn the stereo system on and adjust the main volume control on the stereo to
a
pproximately 3/4 maximum volume. Select one of the adjustment pots on the
A
LOC60
a
nd turn
it slowly clockwise until you notice audio distortion and then stop. Turn the remaining pot to the
same position as the previously adjusted pot. The audio set-up of the
ALOC60 is now complete
and ready to be enjoyed.
