3.1 Laidų jungtys

1. Speaker Level Inputs (1): Connect the factory speaker wires (high-level signals) to these inputs. The LC2i PRO can handle up to 40V input.
2. Power Connector (3): Connect the +12V (constant power), Rmt In (remote turn-on input), Rmt Out (remote turn-on output), and Ground wires. The LC2i PRO requires constant +12V power.
3. Main Outputs (15): These are the RCA outputs for your full-range ampgyvesnis.
4. Bass Output (13): This is the RCA output specifically for your subwoofer amplifier, controlled by the ACR-1 remote.
5. ACR-1 Level Control Input (2): Connect the included ACR-1 remote to this port for remote bass level adjustment.

3.2 Switches and Settings

• Load Select Switch (5): This switch allows for seamless integration with various factory amplifiers. Options include 20 Ω, 60 Ω, and 20 kΩ. Adjust this setting if you experience issues with the factory system detecting an aftermarket load.
• Trigger Mode Switch (6): Select how the LC2i PRO turns on. Options are:
  • Rmt In: Uses a 12V remote turn-on signal from the head unit.
  • GTO (Great Turn-On): Senses a DC offset on the speaker inputs to turn on.
  • Garsas: Senses audio signal on the speaker inputs to turn on.
• Ground Isolation Switch (7): Use this to eliminate noise caused by ground loops. Options include GND (common ground), ISO (isolated ground), and 200Ω (200 Ohm resistor in series with ground). Start with GND and switch if noise is present.

4. Naudojimo instrukcijos

Once installed, the LC2i PRO requires proper adjustment to achieve optimal audio performance.

4.1 AccuBASS Adjustment

The AccuBASS circuit (8, 9, 10) is designed to restore bass that is often rolled off by factory audio systems at higher volumes.

• AccuBASS Level Knob (8): Adjusts the amount of bass restoration.
• AccuBASS Threshold Knob (10): Sets the volume level at which AccuBASS begins to activate.
• AccuBASS Status LED (9): Indicates when AccuBASS is active.

Adjust these controls while listening to music to find the desired bass response without distortion.

4.2 Output Level Adjustment

• Main Output Level Knob (11): Adjusts the output level for the full-range main outputs.
• Bass Output Level Knob (12): Adjusts the output level for the bass output. This works in conjunction with the ACR-1 remote (2).
• Maximized LED (14): This indicator illuminates when the output signal is approaching clipping. Adjust the input and output levels to ensure this LED only flashes briefly on peak notes, indicating a clean, maximized signal.

6. Problemų sprendimas

• Nėra garso: Check all power connections (+12V, Ground, Remote In/Out). Verify speaker level inputs are correctly connected. Ensure output RCA cables are securely connected to the amplifier. Check the Trigger Mode setting.
• Iškraipytas garsas: Reduce input and output gain levels. Check the Maximized LED (14) and adjust levels so it only flashes on peaks. Ensure AccuBASS settings are not over-boosting.
• Noise (Hiss, Whine): Verify proper grounding. Experiment with the Ground Isolation Switch (7) settings (GND, ISO, 200Ω). Ensure RCA cables are not routed near power wires.
• Įrenginys neįsijungia: Check +12V and Ground connections. Verify the Trigger Mode setting. If using 'Rmt In', ensure a 12V signal is present. If using 'GTO' or 'Audio', ensure the factory head unit is on and producing sound.
