L.O.C.PRO™ LP3-4
Line Output Converter
Before You Start
Replacing your radio? PAC also produces RadioPRO
™ which is a radio replacement solution, with steering wheel
control retention built-in. This greatly expedites the installation of a new radio into your vehicle.
To see if there is a RadioPRO
™ interface for your vehicle, visit www.pac-audio.com and search "Radio PRO".
Installation Instructions
The professional way to integrate
your new amplier.
General Overview
Install It Right with L.O.C. PRO™
Don’t cheat yourself out of all the performance your new radio or amplier can deliver. Proper audio line level
matching is critical when replacing your vehicle’s factory (OEM) radio or amplier. 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 ampliers 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.

vehicle specic wiring diagrams.

Speaker Level Input to RCA Level Output
Speaker level input to RCA level output is the most commonly used conguration 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.

Level Adjustment
New School –
Required items: Digital Multi-Meter, Test track media @ 1kHz and 100Hz. Max Amplier Line-level Input Voltage Specication (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 LP3-4 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.
Ampliers 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
multi-meter. Perform the following procedure for each amplier you are installing.
Old School –
1. Start with gain adjustment levels on LP3-4 and ampliers set to minimum.
2. Turn source unit to ¾ maximum volume and play a familiar song that has dynamic attributes.
For example, if your volume goes to 40 you will turn it up to 30 and play a song that has some
quiet sections and some really loud sections.
3. Slowly adjust front channel gain of LP3-4 until just a hint of distortion is audible, and then
back down gain just under that threshold and the distortion goes away. (gure 2)
4. Repeat steps 1-3 for rear channels.

Figure 2
Example:
Amplier 1 (Mid/High frequency) has a maximum 4v input voltage, so you will be targeting a 4
volt output voltage from the LP3-4.
Amplier 2 (Sub frequency) has a maximum 2v input voltage, so you will be targeting a 2 volt
output voltage from the LP3-4.
1. Start with gain adjustment levels on LP3-4 and ampliers set to minimum.
2. Turn source unit to ¾ maximum volume and start test track
(1kHz for mid/high or full range, 100Hz for sub).
3. Choose either left or right channel - With multi-meter, test output of LP3-4 front
channels. Probe with negative on RCA shield and positive in center of RCA output. (gure 1)
4. Slowly adjust level on LP3-4 until you reach the target voltage of the amplier. (gure 2)
5. Repeat steps for rear channels
(if connecting to a different amplier, adjust to that amplier’s voltage requirements)
6. Turn volume down and system off.
7. Connect RCAs, set gains on ampliers to minimum
8. Turn system on and ne tune gains of amplier (if needed).
Note: If using large RCA connectors and have difculty inserting into housing, unsnap the
L.O.C.PRO™ cover and remove insert around RCA outputs.
