Installation Instructions
A2 Channel Adjustable,
Line Output Converter (LOC) with Built-in Amplifier Remote
Generator. The LOC is designed to convert (2) channels of speaker level audio into
(2) channels of line level audio that can be used by OEM amplifiers. It can also be used
with OEM radios to add aftermarket amplifiers. This device will also detect the presence
of an audio signal and then generate a +12V output that can be used to turn-on an
aftermarket amplifier.
Features and specifications
The LOC is able to handle 80 watts per channel continuous input without over heating.
The input circuitry is designed to correct the crossover distortion commonly found on
standard LOCs while providing a high to low level step down of 6:1. Output audio level is
infinitely adjustable using the onboard, high quality potentiometers. The remote output
or amplifier trigger is rated at 500mA (+12V) and will easily handle an outboard relay
if additional current is needed. The remote output will trigger instantaneously when the
LOC detects a DC voltage on the white, left + audio input wire above 5V or a very low
audio signal. It will shut off 60 seconds after no signal is detected.
Installation
The LOC should be installed on a stereo’s speaker output wires or the output wires on
an OEM amplifier of up to 80 watts per channel. These wires can be found behind the
stereo in the dash, on the output of an OEM amplifier, or on the input terminals on the
OEM speakers. Please refer to the wiring diagram for the input connection details.

Wire color and function
The audio and power input wire colors are an EIA standard for car stereo applications
as follows:
Yellow = battery +12v input
Black = ground input
Blue = remote +12v output the above power wires can be connected directly
to the amplifier being added
White = left front (+) input
White/Black = left front (-) input
Gray = right front (+) input
Gray/Black = right front (-) input
Black/White = reference ground (-) (reference ground optional if noise is present)
Note: Be sure that all audio input connections are polarized or in phase with each other.
Failure to do this will result in poor bass response and low quality audio.
Adjusting the LOC for maximum performance: After completing all of the necessary
connections, turn the LOC 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
LOC 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
LOC is now complete and ready to be enjoyed.
