Quick Start Guide

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.
When changing the Load, turn vehicle off, change the Load
and let vehicle sit for 5-10 minutes, then retry.
REMOTE- It is always optimal to adjust the gain at the output side of the
amplier, thus it’s recommended to use the Amplier’s Remote Knob when
available.
