Installation Instructions

The professional way to integrate

your new amplier or radio.

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™ LP7-2 can be used for either replacing an OEM radio and retaining the factory amplied

system or adding ampliers to a system that does not have RCA outputs. L.O.C.PRO™ LP7-2 will also monitor

the audio input signal and automatically create an amplier remote 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™ LP7-2. For specialty applications not covered in this manual, please visit www.pac-audio.com for

Speaker Level Input to RCA Level Output

Speaker level input to RCA level output is the most commonly used conguration for the LP7-2.

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.

Speaker Level Input to Speaker Level Output

Speaker level input to speaker level output is most commonly used when replacing an OEM radio and retaining the factory installed ampliers.

Use this when you need to match levels from a source that only has speaker level outputs and an amplier with speaker level inputs. The RCA input

connectors on the main harness will be used for this type of installation, we suggest cutting them off the harness 3 inches from the RCA end so they

can be used for the wired speaker level output. After all the connections are made, skip to the level adjustment section of this manual.

Cut RCA in half from main harness. Then connect to ouputs of L.O.C to provide wired speaker lead outputs.

Level Adjustment

New School –

Required items: Digital Multi-Meter, Test track media @ 1kHz and 100Hz. Max Amplier Line-level Input Voltage Specication (i.e., 4vrms, 8vrms, etc.)

Proper level adjustment is crucial for obtaining the best possible sound quality. Following the guidelines below will enable you to properly set the

output gain of the LP7-2 using equipment that is readily available. Although this device can be set by ear (Old School), we recommend using a multi-

meter and test tracks for pinpoint accuracy and the least chance of noise.

Ampliers usually have 2, 4 or 8v max line-level input ratings but this can vary. This max line-level input will be your target setting you will read on the
