5. Setup and Installation

Proper installation is crucial for optimal performance. Follow these steps carefully:

1. Disconnect Battery: Before starting any wiring, disconnect the negative terminal of your vehicle's battery to prevent electrical shorts.
2. Mounting: Choose a secure, dry location for the LC11i unit, such as under a seat or in the trunk. Ensure it is away from heat sources and has adequate ventilation. Use the provided mounting hardware to secure the unit.
3. Power Wiring:
   • Connect the +12V terminal of the LC11i to a constant 12V power source from your vehicle's battery. Use an inline fuse (not included, typically 1A) as close to the battery as possible.
   • Connect the Ground terminal to a clean, bare metal chassis ground point in your vehicle. Ensure a good electrical connection.
   • Connect the Remote terminal to the remote turn-on output of your head unit or amplifier. This will turn the LC11i on and off with your audio system.
4. Audio Connections:
   • Connect the Balanced Input (R/L) RCA jacks of the LC11i to the RCA pre-out (full range or subwoofer) of your head unit or other audio source.
   • Connect the Output (R/L) RCA jacks of the LC11i to the RCA input of your amplifier (e.g., subwoofer amplifier input).
5. Remote Bass Knob: Connect the remote bass knob cable to the Dash Remote Port on the LC11i unit. Mount the bass knob in a convenient location within reach of the driver.
6. Reconnect Battery: Once all connections are secure and verified, reconnect the negative terminal of your vehicle's battery.

6. Operating Instructions

Once installed, the LC11i is ready to enhance your bass. Follow these steps to optimize your audio experience:

1. Power On: Turn on your vehicle's ignition and head unit. The POWER indicator on the LC11i should illuminate.
2. Initial Settings: Start with the WIDE and SWEEP controls at their minimum (MIN) positions, and the BASS control at its minimum. The remote bass knob should also be at its minimum.
3. Adjusting Bass Restoration:
   • Play a piece of music that you know has good bass content, or one that you feel is lacking bass.
   • Slowly increase the BASS control on the LC11i until you hear the desired level of bass enhancement.
   • Adjust the SWEEP control to find the frequency range where the bass restoration is most effective and pleasing to your ears. This control allows you to select the center frequency of the bass boost.
   • Adjust the WIDE control to fine-tune the bandwidth (Q) of the bass restoration. A wider setting will affect a broader range of frequencies, while a narrower setting will focus on a more specific frequency.
4. Using the Remote Bass Knob: The remote bass knob provides convenient control over the overall bass output level from your listening position. Use it to make quick adjustments to the bass intensity without needing to access the main unit.
5. Fine-Tuning: Experiment with different combinations of WIDE, SWEEP, and BASS settings to achieve the optimal bass response for various music genres and personal preferences.

Note: Over-boosting bass can lead to distortion or damage to your speakers. Always listen for signs of distortion and reduce the bass level if necessary.
