Indledning
The AudioControl LC2i PRO is a 2-channel line output converter designed to integrate aftermarket amplifiers into audio systems that utilize a factory head unit. It converts speaker-level signals from your factory system into high-quality RCA pre-amp signals, allowing for the addition of external amplifiers and subwoofers. The LC2i PRO features AccuBASS processing to restore bass response that is often rolled off by factory systems, and GTO Signal Sense for automatic turn-on.
Nøglefunktioner
- Two channels of active speaker level inputs, supporting up to 40V (400 watts RMS) power handling.
- Compact chassis design for discreet installation in various vehicle types.
- 9.5V Main and Bass preamp outputs with independent level-matching controls.
- AccuBASS processing for bass roll-off correction, enhancing low-frequency output.
- Active circuitry designed to improve sound quality without compromising bass response.
- Adjustable Threshold and Level controls for fine-tuning AccuBASS processing.
- Load Select switch for matching various factory system impedance requirements.
- Multiple Trigger Mode options: GTO Signal Sense, Audio, and Remote In for flexible turn-on.

Forbindelser
- Strømforbindelser: Connect the +12V terminal to a constant +12V power source. Connect the Ground terminal to a solid chassis ground point.
- Fjernindgang/udgang: The Rmt In terminal can be connected to a switched +12V source if not using GTO or Audio trigger modes. The Rmt Out terminal provides a +12V signal to turn on your aftermarket amplivligere.
- Indgange på højttalerniveau: Connect the factory speaker wires (positive and negative for left and right channels) to the corresponding Speaker Inputs on the LC2i PRO. Ensure correct polarity.
- RCA udgange: Connect the Main Output RCA cables to your full-range amplifier inputs. Connect the Bass Output RCA cables to your subwoofer ampmere livlige input.
- ACR-1 Remote: Connect the ACR-1 remote level control to the dedicated port on the LC2i PRO. Mount the ACR-1 in an accessible location for easy bass level adjustment.
Indledende indstillinger
- Load Select Switch: This switch adjusts the input impedance to match your factory system. Experiment with the 20Ω, 60Ω, and 20kΩ settings to find the one that provides the cleanest signal and prevents factory system errors.
- Triggertilstandsknap: Select the desired turn-on method for the LC2i PRO.
- Rmt In: Uses a traditional +12V remote turn-on signal.
- GTO (Great Turn-On): Detects a signal from the factory head unit to turn on the LC2i PRO and connected amplivførere.
- Lyd: Turns on the unit when an audio signal is detected.
- Ground Isolation Switch: This switch helps eliminate ground loop noise. Try the GND, ISO, and 200Ω settings if you experience unwanted noise in your system.
Betjening og justering
Once installed, the LC2i PRO requires proper adjustment to achieve optimal sound quality.
Niveau Matching
- Primært udgangsniveau: Adjust this knob to match the input sensitivity of your full-range amplifier. The Maximized indicator LED will illuminate when the output signal is optimized without clipping.
- Basoutputniveau: Adjust this knob to match the input sensitivity of your subwoofer amplifier. The Maximized indicator LED will illuminate when the output signal is optimized without clipping.
AccuBASS Control
AccuBASS processing helps restore bass frequencies that factory systems often reduce at higher volumes.
- AccuBASS Level: This knob controls the amount of bass restoration applied. Adjust to your preference.
- AccuBASS Threshold: This knob sets the volume level at which the AccuBASS processing begins to engage. Set it to the point where your factory system starts to roll off bass.
ACR-1 fjernbetjening niveaukontrol
The ACR-1 remote allows for convenient adjustment of the bass output level from your listening position. This control only affects the Bass Output RCA channels.
Opretholdelse
The AudioControl LC2i PRO requires minimal maintenance. Keep the unit free from dust and moisture. Periodically check all wiring connections to ensure they are secure and free from corrosion. Do not use harsh chemicals or abrasive cleaners on the unit.
Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm | Incorrect +12V, Ground, or Remote connection. Blown fuse. | Verify all power connections. Check the fuse on the +12V line. Ensure the Trigger Mode is correctly set. |
| Ingen lydudgang | Incorrect speaker input or RCA output connections. Output levels set too low. AmpLifieren tænder ikke. | Check all speaker input and RCA output cables. Increase Main and Bass Output Level controls. Verify ampfjernbetjening til lifer. |
| Forvrænget lyd | Input signal too high. Output levels set too high. Incorrect Load Select setting. | Reduce factory head unit volume. Adjust Main and Bass Output Level controls. Experiment with Load Select settings. |
| Hissing or Engine Noise | Ground loop interference. Poor wiring. | Adjust the Ground Isolation switch. Ensure all ground connections are solid. Reroute RCA cables away from power wires. |
