DocumentDocumentLPA-2.2 | 2 Channel Line-Output Converter Quick Start Guide LPA-2.4 | 4 Channel Line-Output Converter The L.O.C.PRO ADVANCEDTM can be used to add amplifiers to an audio system that does not have RCA outputs or when replacing an OEM radio and retaining the factory amplified system. Variable Gain Controls with Clipping Indicators, Selectable Ground Isolation and Load Select features ensure a pure, noise-free signal for any type of audio system. This Quick Start Guide will get you going, but if you need additional help or information, please visit our website or contact Technical Support. Features & Wiring Information 12V Connect to a fused +12V constant source GND Connect to a good chassis ground REM IN Remote turn on input (+) REM OUT Remote turn on output (+) The LPA will provide a +9V Remote Output using DC Signal Sense from the Right channel inputs GROUND ISOLATION Selectable: GND / ISO / 200 Default: ISO If ground / engine noise is present, the jumper can be repositioned SPEAKER SIGNAL INPUTS Connect to head unit or amplifier speaker outputs FULLY OPEN TERMINALS BEFORE INSERTING WIRE X LOAD SELECT Selectable: 20 / 60 / 20k Default: 20k For factory audio systems requiring a resistance load to output audio. (See NOTES below) LPF Low Pass Filter Allows 250Hz low pass filter for Rear Channels JUMPERS CAN BE TRIMMED FLUSH GAIN Variable: -28dB--+1dB Allows gain adjustment of the output signal CLIP Indicates signal clipping when gain is set too high REMOTE Optional Remote Level Control Knob (LPA-REM) for Rear Channels. (See NOTES below) RCA SIGNAL OUTPUTS Connect to amplifier inputs BOOST Variable: 0dB -- 12dB When LPF is ON, provides Bass Boost (45Hz) for Rear Channels NOTES: LOAD SELECT- Some late model Dodge/Chrysler/Jeep/Ram/Fiat vehicles require a load for the audio system to work properly: 20 - Vehicles equipped with base audio system. 60 - Vehicles equipped with premium amplified audio system. 20 k - Default, for all other vehicle applications. 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 amplifier, thus it's recommended to use the Amplifier's Remote Knob when available. Example Installation Speaker level input from a radio to RCA level output for an aftermarket amplifier is the most commonly used configuration 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 Positive(+) and Negative(-) wires of two speakers are "tapped" and connected to the SPEAKER SIGNAL INPUTS of the LPA. The speakers will continue to play as normal. The REM OUT is connected to the amplifiers turn-on. When the radio is turned on the LPA will automatically turn on the amplifier. Lastly, the RCA SIGNAL OUTPUTS from the LPA are connected to the aftermarket amplifiers inputs.
