General Overview
Install It Right with L.O.C. PRO
™
Don’t cheat yourself out of all the performance your new radio or amplier can deliver. Proper audio line level
matching is critical when replacing your vehicle’s factory (OEM) radio or amplier. 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.
The L.O.C.PRO™ LP3-2 can be used for adding ampliers to a system that does not have RCA outputs. Level
matching is achieved using precision stereo gain dials and will enable proper adjustment of audio output of the
radio for optimum system performance. Included in these instructions are the most common applications for the
L.O.C.PRO™ LP3-2.
Speaker Level Input to RCA Level Output
Speaker level input to RCA level output is the most commonly used conguration for the LP3-4.
Use this when you need to create RCA level outputs from a source that only has speaker level outputs.
After all the connections are made, skip to the level adjustment section of this manual.
