A Line Output Converter: The Key to Unlocking Your Car Audio
Why a Line Output Converter Matters
Most factory radios are built to provide adequate, but not exceptional, sound quality. However, when you upgrade to aftermarket speakers or amplifiers, the factory signal becomes a bottleneck. This is where a Line Output Converter (LOC) comes in – a device that takes the high-level (speaker) signal and converts it into a clean, low-level (RCA) signal that your new gear can handle.
What to Look for in a Good Line Output Converter
When shopping for a LOC, there are a few key features to look for:
•
- Active LOCs vs Passive LOCS: Active LOCs are the better choice, as they buffer the signal and provide a stronger, cleaner output.
- Adjustable output: Ensure the LOC can handle the voltage output of your factory system, to avoid distortion or damage to your gear.
- Auto-turn-on feature: A convenient feature that automatically turns the amplifier on and off when the radio powers up.
- Built-in signal summing: Allows the LOC to combine multiple audio signals, providing a fuller sound.
- Build quality: A robust, well-built LOC is essential to withstand the rigors of car audio use.
Some top-rated LOCs include the AudioControl LC2i, Wavtech link2, and Kicker KEYLOC.
Installing the Line Output Converter
Setting up the LOC is a relatively straightforward process, but it does require some DIY skills and basic tools. Here’s a general overview of the steps:
•
- Tap into your head unit’s speaker wires
- Connect the LOC
- Run RCA cables to your amplifier
- Secure connections with wire cutters, electrical tape, and/or a soldering iron
However, for complex audio systems or multiple component installations, professional installation is highly recommended to ensure proper wiring, minimize noise issues, and optimize sound quality.
LOC vs DSP: What’s the Difference?
A Line Output Converter (LOC) and a Digital Signal Processor (DSP) serve different purposes in your car audio system. A LOC focuses on converting the factory signal into a usable format for your new gear, while a DSP takes the already-good signal and fine-tunes it for exceptional sound quality.
Key Differences
•
- LOC: Takes the factory signal and converts it into a usable format for your new gear.
- DSP: Fine-tunes the signal for exceptional sound quality, with features like custom EQ curves, timing adjustments, and speaker balancing.
While both can improve your car audio, the LOC is the better starting point, especially if you’re on a budget or new to car audio upgrades. A DSP is typically more expensive and requires more expertise to use effectively.
Conclusion
In conclusion, a Line Output Converter (LOC) is a critical component in unlocking the full potential of your car audio system. By taking the factory signal and converting it into a clean, low-level signal, a LOC sets the stage for exceptional sound quality. When shopping for a LOC, look for active units with adjustable output, auto-turn-on, and built-in signal summing. With proper installation and a good quality LOC, you can experience significant improvements in your car audio – and it’s an upgrade that’s well worth the investment.
