12V
Connect to a fused
+12V constant source
GND
Connect to a good
chassis ground
REM IN
Remote turn on input (+)
REM OUT
Remote turn on output (+)
The LPA will provide a
+12V Remote Output using
DC Signal Sense from the FL
and RL channel inputs
SPEAKER SIGNAL INPUTS
Connect to head unit or
amplier speaker outputs
Use FL and FR for 2CH mode
RCA SIGNAL OUTPUTS
Connect to amplier inputs
GROUND ISOLATION
Selectable: GND / ISO / 200Ω
Default: ISO
If ground / engine noise is present,
the jumper can be repositioned
TURN ON MODE
Selectable: DC / REM
Default: DC
Select DC if using speaker inputs
for turn on, or REM if using REM IN
GAIN
Variable: -27.3dB — +3.2dB
Allows gain adjustment of
the output signal
LPF
Low Pass Filter
Allows 250Hz low pass
filter for Rear Channels
INPUT MODE
Selectable: 2CH / 4CH
Set to 2CH if only using FL
and FR inputs. Set to 4CH
if using all inputs
BOOST
Variable: 0dB — 12dB
When LPF is ON, provides
Bass Boost (45Hz) for
Rear Channels
CLIP
Indicates signal clipping when
gain is set to high
REMOTE
Optional Remote Level Control
Knob (LPA-REM) for Rear Channels
LOAD SELECT
Selectable: 20Ω / 60Ω / 20KΩ
Default: 20KΩ
For factory audio systems
requiring a resistance load to
output audio, select 60Ω first,
then 20Ω. All others use 20kΩ
setting

The L.O.C.PRO ADVANCED™ can be used to add ampliers to an audio system that does not have RCA outputs or when
replacing an OEM radio and retaining the factory amplied system. Variable Gain Controls with Clipping Indicators, Selectable
Ground Isolation and Load Select features ensure a pure, noise-free signal for any type of audio system.

Speaker level input from a radio to RCA level output for an aftermarket amplier is the most com-
monly used conguration for the L.O.C.PRO ADVANCED. This will create RCA level outputs from a
radio that only has speaker level outputs.
In the example below, the 4 speaker outputs from the factory radio are disconnected from the
speakers and connected to the SPEAKER SIGNAL INPUTS of the LPA. The REM OUT is connected
to the ampliers turn-on. When the radio is turned on the LPA will automatically turn on the amplier.
The RCA SIGNAL OUTPUTS from the LPA are connected to the aftermarket ampliers inputs. The
speaker outputs from the aftermarket amplier are then connected to the speakers.
