Install It Right with L.O.C. PRO
Don't cheat yourself out of all the performance your new radio or amplifier can deliver. Proper audio line level
matching is critical when replacing your vehicle's factory (OEM) radio or amplifier. It can be the difference
between a great sounding system that you enjoy every day and a buggy, noisy mess that drives you crazy.
PAC L.O.C.PRO™ interfaces have been professionally designed for those who want the very best.

General Overview

The L.O.C.PRO™ LP7-4 can be used for either replacing an OEM radio and retaining the factory amplified
system or adding amplifiers to a system that does not have RCA outputs. L.O.C.PRO™ LP7-4 will also monitor
the audio input signal and automatically create an amplifier turn-on for systems that do not have one. Level
matching is achieved using precision stereo gain dials and will enable proper adjustment of audio output of the
radio for optimum system performance. Differential inputs also allow for use in OEM BOSE and other premium
system scenarios. Included in these instructions are the most common applications for the L.O.C.PRO™ LP7-4.

Speaker Level Input to RCA Level Output
Speaker level input to RCA level output is the most commonly used configuration for the LP7-4.
Use this when you need to create RCA level outputs from a source that only has speaker level outputs.
The RCA input connectors on the main harness will not be utilized for this type of installation, we suggest
cutting them off the harness 3 inches from the RCA end so they can be saved and used for a future installation.
After all the connections are made on the remaining wires, skip to the level adjustment section of this manual.
