Allows gain adjustment of
the output signal
LPF
Low Pass Filter
Allows 250Hz low pass
filter for Rear Channels
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 Con-
trol Knob (LPA-REM) for Rear

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

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 commonly 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 Positive(+) and Negative(-) wires of two speakers are “tapped” and connected to the SPEAKER SIGNAL
INPUTS of the LPA. The speakers will continue to play as normal. 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. Lastly, the RCA SIGNAL OUTPUTS from the LPA are connected
to the aftermarket ampliers inputs.
